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.

TERRASEI LINE

Because of history and presence on the market, different formulations of TERRASEI LINE are one of the most important allies in the plant nutrition. The proper combination of organic and mineral components determines the characteristics of TERRASEI LINE; different NPK relations adapt to the needs of crops in their different phenological stages. The organic fraction improves physicochemical properties of agricultural soils and produces the biological activation of the rhizosphere.

  • Optimizes crop yields.
  • Improves crop quality: precocity, size, smoothness and ripening.
  • Nutritionally balanced plantations.
  • Contribution of amino acids, fulvic acids and organic matter.

 

MULTISEI LINE

The MULTISEI LINE includes our liquid organic fertilizer par excellence. This is a range of products that regenerate soil, because  in addition to nurture, improve the structure, composition and microbial activity. The contribution of organic matter recover soil, balancing its content.

  • Improve macro and micronutrients absorption.
  • Increase the cation exchange capacity and the storage of nutrients in the soil.
  • Activate nutrient mineralization processes.
  • Contribute to the formation of soil aggregates that improve soil friability, facilitating farming, avoiding waterlogging and root suffocation.
  • MULTISEI, MULTISEI K and MULTISEI Mg are an important source of macro and micronutrients, especially relevant in intensive crops, nurseries and seedbeds.
  • Improve the efficiency of chemical fertilizers.
  • The liquid formulation is an advantage over the organic solids, because reach the main area of root uptake.
  • MULTISEI, MULTISEI K and MULTISEI Mg contain in their formulation raw materials of plant origin with a high degree of refinement, that avoid precipitation problems and seals in drip irrigation systems.

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.
