Calcium in crops: why proper assimilation is important

calcio en los cultivos

Calcium in crops plays a key role in agricultural development. Its existence guarantees firmer fruits. Agricultural calcium is necessary not only in structural strengthening of walls but also in the elasticity of the vegetal tissue. It is essential to have resistant and healthy plants.

Calcium shortage severely affects the quality of fruits and crop yield. This is the reason why an inappropriate assimilation can cause losses in the market value. Fortunately, there are treatments to improve calcium assimilation in crops. Its application is markedly necessary at the beginning of spring, when climatic conditions such as thermal amplitude between day and night can subject plants to stressful situations.

Calcium in crops is transported internally by xylem, but calcium has low mobility within the plant. Translocation results in a difficult process, since only a small percentage of calcium is translocated to the fruits from the surrounding leaves.

There are many climatic factors affecting calcium assimilation in crops. High temperatures on sunny days, wet and dry winds, and low relative humidity may become factors promoting high levels of transpiration. When this transpiration stream is too high towards the foliar organs, contribution of calcium to the fruit is restricted. In other words, for calcium is more difficult to reach those organs with low transpiration rate.

As we saw in an earlier entry, calcium deficiency in crops is observed in alterations such as BER (blossom end rot) in tomato and pepper. In strawberry or lettuce symptoms are perceived at the end of the expanding leaves (tip burn).

Guaranteeing contribution of calcium in crops

By evaluating calcium status in plants, it is possible to diagnose disorders like BER. In order to prevent such deficiencies, Seipasa has developed the Calcisei line of products. These products, formulated with calcium, play a pivotal role in crop development. Besides contributing to prevent deficiencies such as BER, tip burn or bitter pit in tomato and apple, the Calcisei line is specifically prepared for the structural strengthening of cell walls and membranes, as well as the management of soils with high content of salt.

Within this line, Calimax is a treatment designed to prevent calcium deficiencies in crops while confronting physiopathies. Calimax improves soil structure, promotes optimal root development and regulates imbalances due to lack of calcium.

Guadal Ca has been produced to avoid problems of internal decay and cracked fruits, as well as to confront apical rot, tip burn in horticultural crops. Lack of calcium usually concentrates on young leaves and fruits, since these are the organs having major transpiration difficulties. Guadal Ca is especially recommended for foliar applications in the second half of the crop cycle given the rapid absorption and total safety.

Apart from the contribution of calcium, the organic matter content of the Calcisei line brings significant benefits to the crop, especially in the post-harvest quality.

Soil correctors

Farmers are aware of how important is to have calcium in soils. Calcium deficiencies in plants can be observed in soils where there is an excess of nitrogen fertilizer, in substrates with alkaline pH, with episodes of water stress or with salt excess, among other factors. Within the Calcisei line, Miñosal is a corrector of saline and saline-sodic soils. It can be used both in soils having salinity problems and in areas where irrigation water quality makes it necessary.

Treatments for olive trees after winter

Tratamientos-para-el-olivo

Treatments for olive trees after winter are widely recognized to prevent diseases and to obtain a homogenous harvest each season, thus forgetting the feared alternation of production. Preparatory treatments are applied at an early stage and aim to adapt the olive tree to achieve a good flowering.

The months of January and February are suitable to apply pruning work at the olive tree, allowing to set a proper structure within the production of the following campaign.

Although depending on climate and varieties, towards the end of March the flower buds have already begun to appear. In this second phase, the buds gradually thicken until the generation of the floral bud begins to be observed. Henceforth, the plant will continue its development with the formation of the cluster.

At this point, treatments for olive trees after winter recommend the use of products such as Kynetic4. Its use allows to enhance the flowering of the crop, an essential step to assure the harvest of the following year. Kynetic4 produces an energetic stimulation at times of increased crop demand. Its application contributes to obtain a better flowering and the following setting.

Treatments for olive trees: fungal diseases

At this stage of the harvest, it is utterly necessary to pay attention to the possible occurrence of fungal diseases such as repilo. Treatments for olive trees after winter also include the application of preventive products based on copper.

The copper placed on the leaf creates a protective barrier that precludes the spore from germinating when it appears. The use of Glucosei favors the creation of this protective barrier and stimulates the generation of self-defenses. Due to its formulation, Glucosei minimizes the possible negative effects caused by the copper on the soil.

March results a time of the year when the latest winter rains and the earliest of the spring may become commonplace. The use of Glucosei also helps to ensure that crops are protected when spring budding occurs.

Micronutrient correctors

Specialists also recommend the application of a micronutrient corrector as a treatment for olive tres after winter. The plant assimilates them during the budding, overcoming any shortage of micronutrients that may occur and reinforcing the subsequent phase of flowering. Based on a combination of zinc, manganese, iron, boron and molybdenum, Seipafol Mix has been specifically designed to beat any shortage of micronutrients that may occur during the different stages of plant growth.

Not only does the use of natural solutions bring greater energy to the vegetable, but It also contributes to maintaining the balance of the agricultural ecosystem, respecting sustainability and revitalizing the environment. Thus, besides contributing to the development of the crop, natural treatments help to guarantee the conditions in which both olive trees and fields are left in proper conditions for future campaigns.

Fertilizers for tomato fattening

Fertilizers for tomato fattening

 

Best fertilizers for tomato fattening contain organic matter, potassium, fulvic and humic acids, and microelements.

Fertilizante para engorde de tomate

Achieving the highest harvest percentage with proper size and color is the goal of all farmers. This is very important to market the products. Hence the importance of assessing the application, at the appropriate time and following the needs of the plant, of fertilizers for tomato fattening and, where appropriate, specialized biostimulants.

When the fruit setting phase, the plant requires an extra contribution of potassium. Deficiency of this element can lead to an irregular maturation, preventing the full formation of the fruits in many cases.

Symptoms of potassium deficiency can be observed by small fruits with non-uniform coloration being produced, with yellow spots in areas that do not mature enough. It also leaves weak stalks, chlorosis and scorched edges on the leaves, poor resistance to pests and diseases, as well as increased susceptibility to frost and droughts.

Fertilizers for tomato fattening: potassium and much more

The relationship between potassium, fruit growth and maturation shows the importance of this macro-element in the quality of crop production. However, other factors must be taken into account to ensure the size, color and flavor of the tomato, without harming the characteristics of each variety.

Besides the need for a nutrient balance, with an adequate balance of other macro-elements and micro-elements such as Boron, Molybdenum, Calcium or Magnesium, environmental factors such as temperature must be taken into account. Between 24 and 28 degrees (Celsius) or solar lighting are  optimal for maturation. The characteristics of the substrate significantly influence the process, since this is the natural source of nutrients.

Fertilizers for tomato fattening: the importance of the substrate

The most demanding agricultural producers look beyond the specific application of mineral nutrition. They pefer to ensure not only the size of the fruits in that campaign, but also the richness of the soil that gives them greater guarantee of success for the next crops. What is key is to take advantage of all nutrients in the substrate while maintaining the balance of the substrate for short and long term benefit.

The most suitable tomato fattening fertilizers are those combinig organic matter with high content of potassium. Some very specialized references even contribute fulvic and humic acids, vitamins and microelements. This is the case of Terrasei Fruit, from SEIPASA.

The role of organic matter in tomato fattening fertilizers

Potassium fertilizers with high content of organic material such as Terrasei Fruit, significantly reduce potassium fixation inside the clays and its leaching loss in sandy soils. They increase both the concentration of potassium available and in solution in the soil. Its use favors the structure of the substrate, but also improves the absorption of potassium provided by conventional fertilizers.

Fulvic and humic acids contained in this reference are essential to regulate the physical and chemical properties of the soil and also to favor the development of beneficial microorganisms. This fertilizer has an immediate and slow release effect, helping to provide nutrients gradually.

Early maturation by applying fertilizers for tomato fattening

With the same conditions of temperature and illumination, it is possible to obtain a greater precocity and organoleptic quality in the process of maturation. This is because of fertilizers for tomato fattening. When it comes to Terrasei Fruit, results of the studies reveal considerable advance in maturation. As shown in figure 1 (corresponding to an experiment in which four applications of the product were carried out from fruit setting to harvesting) harvesting of the first fruits after maturation (days to first pick) was advanced 21 days.

Figure 1.- Days to first pick.

Fertilizers for tomato fattening: performance, size and color

Apart from favoring fruit maturation, field studies confirm that Terrasei Fruit ensures high performance (see figure 2) and a marked improvement in size (see figure 3), color (see figure 4), plant growth, length root and sugar content. Additional test data can be found here.

Advantages of liquid format in tomato fattening fertilizers

Organo-mineral fertilizers in liquid form such as Terrasei Fruit reach deeper soil profile compared to solid organic matter.

Biostimulants for tomato maturation and fattening

Biostimulants result in a specialized option so as to induce maturation and fattening of fruits and, depending on the characteristics of the crop and needs, could be combined with fertilization.

A reference specially addressed to this purpose, foliar and root application, is Sweetsei. This is a biostimulant of rapid assimilation. Besides advancing maturation, it increases fruit size while achieving uniformity and excellent color. Furthermore, it obtains greater elasticity, hydration and firmness due to an organic polymer incorporated in its composition. In the same way, it improves fruit behavior in post-harvest and favors the formation of sugars, improving the index of Brix degrees.

Seipasa produces natural treatments for agriculture with zero residues.

Biostimulants for the zucchini setting

Biostimulants for the zucchini setting that increase quality and production by minimizing the use of hormones

* Avoid fruit malformation

* Influence on flowering and fertility

* Minimizing the use of hormones

* Greener and brighter fruits

Biostimulants for the zucchini setting. Flowers

The process of fruit setting in zucchini cultivation is especially complicated compared to other horticultural crops because the opening and development of male and female flowers do not coincide. Male flowers usually appear earlier.

As this is a crucial phase to achieve an abundant and quality harvest, farmers often resort to hormonal treatments to induce the development of fruits.

However, both the social demand and the evolution in the regulation of products are increasingly directed at trying to dispense with any chemical in plant foods, thus prioritizing the use of natural processes and substances. The market requires minimizing the use of hormones and synthetic products.

In this context, the use of specialized biostimulants for the zucchini setting and even their combination with hormonal treatments in low proportions has been shown an efficient alternative to obtain high productivity and, most importantly, quality. KYNETIC4 is one of the biostimulants that achieve high levels of fruit setting with top quality crops.

Biostimulants for the zucchini setting that avoid fruit malformation

A bad process of zucchini setting can produce malformations in the fruits such as the so-called sucking, crooked or low-developed fruits.

Crooked fruits: 

Zucchinis that bend by the centre due to a bad setting of the fruit

Low-developed fruits:

Fruits that stop their development in an early stage and that finally abort. Possible causes are depletion of the plant, lack of vegetative vigor or phytosanitary treatments.

Sucked fruits: 

Fruits that do not develop evenly and are usually sucked by the apical limb. Precisely this defect has been traditionally attributed to hormonal treatment; However, there is a conjunction of factors that can provoke it, since it usually occurs in the moments of plant stress (scarcity or excess humidity, dry winds, abrupt climatological changes or phytosanitary treatments). When pollination is natural, the fruit is better able to withstand stress, and this problem does not occur.

Products for the zucchini setting that give the plant the energy boost it needs to overcome situations of plant stress are fundamental to avoid any type of malformations of the fruits.

roductos para el cuajado en calabacín que, al mismo tiempo, otorguen a la planta el impulso energético que necesita para superar las situaciones de estrés vegetal se hacen fundamentales para evitar cualquier tipo de malformaciones de los frutos.

Influence on flowering and fertility of biostimulants for the zucchini setting

Since the development of the male and female flowers of the zucchini crop do not match, it is very important to achieve sufficient quantities of flowers and, more importantly, with abundant pollen and high fertility. If a natural pollination is carried out, this allows the pollinating insects to carry out their work more successfully.

Specialized biostimulants such as KYNETIC4 are specially designed to increase flowering, pollen fertility and fruit setting levels. In addition, it is an essential solution to deal with all types of plant stress conditions.

Biostimulants for zucchini setting: Minimizing the use of hormones

The constant demand for increased yields and quality of crops and the need to reduce the use of hormones led SEIPASA to be involved in studies aimed at the organic activation of plants in the cultivation of zucchini decreasing the use of hormonal products. The KYNETIC4 biostimulant was used for this purpose.

LINK TO THE TRIAL “Effect of KYNETIC4 on zucchini quality, fruit set and yield”: http://en.seipasa.com/trials/kynetic4-zucchini/

For this trial, four different treatments were proposed: T1, corresponding to the usual application of two hormones (ANA + ANA amide); T2, with the application in irrigation of KYNETIC4; T3, with the foliar application of KYNETIC4; and, finally, T4, which consists of combined applications of the hormone and KYNETIC4, reducing the amount of hormone used in T1 by almost 60%.

According to the results of the study, it is possible to reduce the use of hormonal products (T4) up to 60%, increasing the average weight of the marketable fruit with respect to the single use of hormones. (Graphic 1)

Biostimulants for the zucchini setting. Weight

There is also a significant improvement in the quality of the harvest: In the crop with combined application (T4), a higher quantity of fruits of the first quality and less amount of second and ‘rejects’ were obtained. (Graphic 2)

Fertilizantes orgánicos para mejorar el suelo en cultivos intensivos

Organic fertilizers to improve soil in intensive crops

Organic fertilizers Multisei and Terrasei are the greatest impulse for horticultural soil fatigued by the intense activity and poor quality of the water

Organic fertilizers Terrasei y Multisei

Calcareous soils, saline waters and two or three crops per year on the same land. These conditions that combine the horticultural crops of the southeast of Spain carry the risk of soil fatigue, which implies loss of vigor and productive yield of the plants.

The degradation of the structure and physical properties of the substrate accelerates the incidence of chemical and biological factors, such as nutrient deficiency due to exhaustion or blockage, contamination by phytotoxic ions or by pathogenic organisms, competition between microorganisms and cultivated plants, or loss of the biological balance of the soil by the use of disinfectants.

Being aware of this problem, producers are looking for solutions that maintain productivity and quality in their fields, and find great support in specialized organic fertilizers for this purpose such as Multisei and Terrasei.

Organic fertilizers to regenerate soils and increase fertility

Multisei line products of SEIPASA are specially designed to regenerate punished soils due to their high content of organic matter of vegetal origin and of fulvic acids, optimal C/N ratio and incorporation of molasses. “Molasses are the main source of energy of the microorganisms involved in the fermentation of organic fertilizer. So they favor the microbiological activity of the soil, and contain micronutrients, too”, underline the technicians of the area”.

All this leads to an improvement of the structure and composition of the soil, increasing the porosity and, therefore, the capacity of air and water retention, as well as the availability of elements.

The Technical personnel especially emphasize the high solubility of this liquid organic fertilizer, with a high degree of refinement of its raw materials, which avoids problems of obturation in the drip irrigation systems.

Stimulation and root protection

Multisei also enhances the action of biostimulants and root protectors such as Seiland, a product of great capacity in the biological activation of the rhizosphere that becomes essential in the planting phase: “Promoting beneficial microorganisms of the soil provides a protective barrier and a reinforcement of the root system against pathogen attacks and root diseases”.

With the decrease in temperatures, horticulture especially need this boost to activate the plant. “Seiland encourages the crops to emit new roots and acts as biofertilizer because of its ability to fix nitrogen or solubilize phosphorus and because it provides beneficial substances and enzymes”, explain the technicians of SEIPASA.

Nutrition Bioactivators

In addition, the action of Terrasei as a bioactivator of nutrition is essential. As the technical personnel explain, although the references of the Terrasei line (liquid organomineral fertilizers) contain NPK, the true value of their complex formulation lies in the conjugation of these elements with other molecules that complement nutrition and facilitate nutritional absorption, provided that they are capable of unblocking the substratum and liberating the nutrients.

Terrasei products improve the efficiency of chemical fertilizers by increasing the cation exchange capacity and, consequently, the storage of nutrients in the soil. This represents a saving in the long run for the farmer since it allows to reduce the amount of pure synthetic fertilizers to apply.

“They incorporate, in addition to organic matter, fulvic acids and amino acids, which translates into a jolt of energy that allows the vegetable to dedicate metabolic resources to physiological functions”. The possibility of foliar use, besides irrigation, allows a rapid assimilation of nutrients.

New regulations: EU endorses organic and waste-based fertilizers

  • It will facilitate free circulation of organic fertilizers in the EU, putting them on equal terms with inorganic fertilizers

  • The regulation will offer greater market opportunities for innovative companies

Free circulation of organic and waste-based fertilizers in the EU market will become a reality after the new fertilizer regulation proposed by the European Commission is approved. Thus, they will be on an equal footing with inorganic fertilizers. Current regulations –effective since 2003– exclude fertilizers made from organic materials, so that their access to the community market had major obstacles due to the divergence of national rules.

“From the plentiful of resources available in the form of organic waste, very little of them are transformed into valuable fertilizer. Our farmers use fertilizers made of imported resources or with a lot of energy use involved, even though our industry could make bio-waste into valuable recycled nutrients”.

The phrase belongs to Jyrki Katainen, Vice-President of the European Commission in charge of its Jobs, Growth, Investment and Competitiveness area, while he was introducing the proposed new provisions on organic and waste-based fertilizers, which will greatly facilitate their access to the EU’s community market, “placing them on an equal footing with traditional inorganic fertilizers”.

This will create new market opportunities for innovative companies, while reducing the volume of waste, energy consumption and damage to the environment, argues the European Commission. “The new Regulation will help us turn challenges into opportunities for farmers and businesses”, says Katainen.

These new provisions would be the first measure of the circular economy package adopted in December 2015, which has the reuse of raw materials currently disposed of as waste as one of its key principles. This way, the European Union values the use of more environmentally friendly products.

Biowaste conversion

The new text lays down common rules about the conversion of bio-waste into raw materials that can be used to manufacture fertilizers. It defines the requirements for safety, quality and labeling requirements all fertilizer products must comply with in order to be freely sold throughout the EU. “Producers will have to demonstrate their products meet these requirements and comply with the limits for organic pollutants, microbial contaminants and physical impurities before marking them with the CE label”, says the European Commission.

In this sense, the Regulation sets strict limits for cadmium in phosphate fertilizers. The limits will become more stringent, from 60 mg/kg to 40 mg/kg in three years, and 20 mg/kg in twelve years, thus reducing health and environment risks.

The new rules will apply to all types of fertilizers in order to ensure the highest level of soil protection.

CE labels or national standards

Since some fertilizers are not produced or marketed across borders in large quantities, the Commission proposes optional harmonization: the manufacturer may choose, depending on its business strategy and product type, the CE labels, which enables its free trade on the domestic market in accordance with common European standards, or to sell it according to national standards based on mutual recognition in the community market. This guarantees the regulation improvement and subsidiarity principles are taken into account.

The scope of the current 2003 Regulation does not include “innovative fertilizers obtained from organic materials”, since it only guarantees free circulation within the internal market of conventional inorganic fertilizers, which “are usually obtained from mining or produced by chemical processes that consume energy and generate a lot of CO2”.

Thus, access organic fertilizers to the EU market of currently depends on mutual recognition among Member States and, “due to the divergence of national rules, it is often difficult”, stated the European Commission.

Besides, the Regulation on fertilizers in force “does not address the environmental concerns arising from contamination of soils, inland waters, marine waters and, ultimately, food”.

“Today, only 5% of bio-wastes are recycled. According to estimates, if more IP/16/827 biowaste were recycled, they could substitute up to 30% of inorganic fertilizers”, said the same sources, while highlighting the fact that “each year, the EU imports about 6 million tons of phosphates, and it could replace up to 30% of that extracting them from sewage sludge, biodegradable waste, meat and bone meal or manure”.

European Parliament and Council

The draft regulation will now be sent to the European Parliament and the Council, which must adopt it. Once adopted, it will be directly applicable without transposition into national law, after a transitional period for enterprises and public authorities to adapt to the new rules.

Vines and olive trees: Soil preparation for a successful campaign

When the time comes to fertilize vines and olive trees, the question to be asked is which product to use to achieve the best results.

The correct soil preparation in order to lend it a nutrient balance is critical for having a good campaign. It is one of the practices that influences the most in the harvest’s production and quality, and must be as respectful as possible of the environment, preventing leachate and runoff.

Although the necessary macronutrients (nitrogen, potassium and phosphorus) are naturally in the soil, they will not replenish fast enough to maintain soil fertility. That is why it is necessary to make additional contributions. But which fertilizer should be used?

Based on the securities that offer organic full fertilizers compared to synthetic fertilizers and even manure (See: The benefits of 100% organic full fertilizers), before choosing one or the other soil and foliar analyses should be carried out in order to grasp the exact needs of each crop.

Not only the characteristics and composition of the substrate must be taken into account, but also the type of plant material, age, agricultural practices, water status or planting density used, among other items. It is also important the observation of the farmer on the development and evolution of plants.

In keeping with these circumstances to try to prevent nutrient deficiencies and excesses, fertilizers can be applied as efficiently as possible through its specific formulation, fractionation and / or its adaptation to the stage of the crop cycle when its availability is the most appropriate.

Fertilizers for new olive trees and vineyards

Fertilizers Organitro and Seivital K

At the current stage of the production cycle of the olive tree, it needs all the energy to develop its leaf mass, and one of the best options – due to its formula –  is full fertilizer Organitro®, which includes much nitrogen and is 100% organic. Accordingly, it is the most appropriate reference for new vines.

Its high organic matter content substantially improves the soil’s chemical, physical, and biological properties. It also increases its capacity of cationic exchange* and acts as a buffer agent to lower the tendency to sudden pH change in the soil when acidic oralkaline reaction substances are applied. It also allows the formation of organometallic complexes, thus stabilizing soil micronutrients that otherwise would not be profitable.

It is crucial to stimulate the plant metabolism and crop revitalization, especially during periods of peak nutrients demand, in order to achieve higher productivity, and references like this are essential.

Vines in production

For vines in production, with higher potassium requirements, you can use specialized solutions such as Seivital K. It is an organic fertilizer with a high percentage of this essential macronutrient, which also makes it the most appropriate when crops are into the flowering and setting periods.

Thanks to its input of organic matter and humic acids, allows farmers not only to improve soil structure by increasing cation-exchange capacity, but also boosts microbial activity and the availability of exchangeable potassium at the time it favors the transformation of this nutrient, which is included in the soil in a form that cannot be absorbed by the plant.

*Ability of soil to retain and release cations. The most important cations related to plant growth are calcium (Ca), magnesium (Mg), potassium (K), ammonium (NH4 +), sodium (Na), and hydrogen (H). The first four are nutrients directly involved in plant growth. Sodium and hydrogen have a pronounced effect on the availability of nutrients and moisture.

The benefits of 100% organic full fertilizers

Full organic fertilizers (with contain the three primary nutrients: nitrogen, phosphorus, and potassium) offer many benefits to crops compared to chemical fertilizers and even manure.

Put against manure variability, they guarantee fertilizer units (N, F, K) while they ensure the absence of weed seeds or pathogens that can migrate from manure to crop. Besides, many kinds of manure are not allowed in organic agriculture: those from intensive livestock farms are likely to be tainted with antibiotics, pesticide residues or heavy metals.

On the other hand, some kinds of manure very rich in macronutrients, such as nitrogen, if not mixed with poorer manure or plant remains, tend to imbalance despite composting.

Regarding synthetic fertilizers, the benefits are more evident, both for the crop and the environment, in the short and especially in the long term.

Although using of inorganic fertilizers contributes with immediately available nutrients to the plant, it is easy to employ them excessively or deficiently.

Chemical fertilizers do not amend the soil

Besides the chance of contamination of surrounding and underground water, and the increase of toxic salts in the soil when applied in large quantities, soil degradation is a significant risk in the single use of chemical fertilizers, since it eliminates useful microorganisms for plant nutrition. The simple fact is synthetic fertilizers fail to amend the substrate – they only feed the plant.

When organic fertilizers are applied, soil microorganisms themselves degrade them until they become water-soluble compounds that plants take advantage from. Another valuable feature is that they achieve the increase of activity in bacteria and fungi that benefit the soil. In fact, this kind of fertilizers boost the proliferation of fungi responsible for plants to take advantage of nutrients.

Thus, organic fertilizers improve soil structure, help to retain nutrients, allow carbon fixation in the substrate and enhance the ability of the crop to absorb water.

100% organic guarantee and official certification

This natural effectiveness can be found in specialty formula fertilizers tailored to the requirements of each crop in each time of the production cycle. The different lines of SEIPASA fertilizers are a sample of the best options for natural nutrition.

SEIPASA offers 100% organic guaranteed fertilizers, supported by an environmental certificate, which are great for integrated production.

The balanced composition of the Multisei and Seivital products lines (liquid and solid organic) place them as regenerating soil models for their ability to balance the substrate nurturing, improving its structure, composition and microbial activity.

Multisei fertilizers also promote the formation of soil aggregates that improve soil friability, which facilitate farming and prevent waterlogging and root asphyxia. In the same line, they include on their formulations vegetable raw materials with a high degree of refinement that avoid problems such as precipitates and clogged drip irrigation systems.

Seivital solid fertilizers, featuring pellets that get distributed on the soil easily and uniformly, allow immediate availability as they disintegrate in just five minutes in the presence of water and dissolve completely in no more than four hours. This achieves the maximum yield per added fertilizer units.

They ensure a fertilizer of organic origin, free of pathogens, antibiotics and weed seeds, while also free from Salmonella, Enterobacteriaceae, and Streptococci.

When regularly applied, they are the best solution to enrich and restore eroded soils, compacted or depleted, since they achieve the increase of porosity of the substrate as long as they allow greater air circulation, as well as rapid infiltration and greater retention of rainwater or irrigation water.

SEIPASA’s Terrasei line is a response to the nutritional needs of crops in different growth stages, since it combines mineral nutrition with the energy input and the soil structuring contribution of organic fertilization. 

Furthermore, these products include a percentage of aminoacids in their composition, which results in an energy plus for crops, since they allow the plant to use up its metabolic resources for primary physiological functions.
