Organic fertilizers for olive trees

Organic fertilizers for olive trees. Advantages versus manure and conventional fertilizers

Organic fertilizers for olive trees

The organic fertilizers for olive trees are an essential element for the soil health of these crops. The advantages of an organic bottom fertilizer, used in the first cycles, versus manure or conventional fertilizers, are not only observed in the most immediate campaign, but also in the plant health and the quality of the long-term production.

Although nutrients are naturally found in the substrate, they are not replenished fast enough to maintain soil fertility. Hence, it is necessary to make additional contributions. But which fertilizer to use?

Before choosing one or the other to include in the subscriber plan it is advisable to carry out a soil and leaf analysis to know the exact needs of each crop. Some parameters such as soil characteristics and composition, type of plant, age, agricultural practices, water status or planting density should be taken into account.

Nowadays, one of the most advanced organic formulations for the basal dressing is Organitro, from SEIPASA, rich in nitrogen and 100% organic.

Organic fertilizers for olive trees vs. dung

– The dung contains high humidity and is not stable. Thus, in contrast to the dung variability, the complete organic fertilizers guarantee the fertilizer units (N, F, K).

– Dung can contain seeds of weeds or pathogens that can be transferred to the crop.

– If some dungs rich in macronutrients such as nitrogen are not mixed with other poorer or plant remains, they tend to be imbalanced despite composting.

– In organic farming, many dungs are not allowed: Those from intensive farms may be contaminated with residues of pesticides, antibiotics or heavy metals.

Organic fertilizers for olive trees vs. conventional fertilizers

– Conventional mineral fertilizer gives the plant nutrients available immediately, but it is easier to apply in excess or deficiency. It does not amend the soil, simply feeds the vegetable.

– The organic fertilizer is less aggressive to the soil. Conventional can salinize the substrate. It can increase toxic salts if applied in large quantities.

– With the use of chemical fertilizers there is a risk of contamination of the underground and surrounding water.

– The application of synthetic fertilizers can also lead to degradation of soil life by eliminating microorganisms useful for plant nutrition.

– Applying organic fertilizers allows the action of the soil microorganisms to degrade the fertilizer to form water soluble compounds, which the plant takes advantage of.

– Organic fertilization also favors the proliferation of bacteria and fungi that benefit the soil and help the best use of nutrients by the plant.

– In short, they improve the structure of the substrate, allow carbon fixation and favor the ability of the crop to retain nutrients and water.

Organic fertilizers of reference for olive trees

Organic fertilizers for olive treesFor the basal dressing, one of the best options is the complete fertilizer with Organitro.

The high organic matter content of this fertilizer substantially improves the physical, chemical and biological properties of the soil.

It is easy to handle in the application thanks to the pelletizing. It is distributed with great uniformity in the soil, allowing an immediate availability when disintegrating in only five minutes in the presence of water and dissolving completely in no more than four hours.  It achieves a maximum valuation of the supplied fertilizer units.

It has a dual nutritional effect: the combination of fast-release nutrients and elements that ensure fertility in the medium term after undergoing mineralization processes. It allows the formation of organo-metallic complexes. Thus, it stabilizes micronutrients of the soil that would otherwise not be usable.

Organitro increases the cation exchange capacity and acts as a buffering agent by reducing the tendency to a sudden change in soil pH when acid or alkaline reaction substances are applied.

To have an oxygenated soil, with good structure and balanced in its nutrients is the ideal thing so that the farmer can obtain good yields, and references like this are basic.

Organic solid and liquid fertilizers

In addition to Organitro, belonging to the Seivital line (solid organic), SEIPASA offers another type of 100% organic fertilizers, guaranteed with the corresponding ecological certificate, and ideal for integrated production.

The liquid organic fertilizers of the line Multisei are also placed as regenerative models of soils for their ability to balance the nutrient substrate, improving its structure, its composition and microbial activity.

They promote the formation of aggregates in the soil that improve the friability of the land facilitating agricultural work and avoiding flooding and root suffocation.

They incorporate in their formulation raw materials of vegetal origin with a high degree of refinement that avoid problems of precipitates and seals in systems of drip irrigation.

The Terrasei line is the answer of SEIPASA to the nutritional needs of crops in different phenological states, since it combines mineral nutrition and the energy and soil structure of organic fertilization.

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.

Multisei y Terrasei

Multisei and Terrasei fertilizers

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.
