TECHNICAL NOTES

Fertigation is increasingly used for some types of crops, both to overcome the alterations that can occur for different causes (insufficient absorption, inadequate distribution, persistent low temperatures, drought, soil compaction, excessively alkaline pH), and to optimize crop operations by obtaining more homogeneous productions with a higher commercial quality. In this context, the NEWFERSTIM and AXIFERT lines, SCAM liquid organo-mineral fertilizers, obtained from highly soluble salts and from an organic matrix studied for the purpose, can better rationalize fertigation operations and obtain better qualitative and quantitative results. The lines of SCAM liquid organo-mineral fertilizers differ in the organic matrix, which is vegetable in AXIFERT and animal in NEWFERSTIM.

LIQUID ORGANO-MINERAL FERTIRRIGANTS SCAM

As for the solid organo-minerals, also for the NEWFERSTIM and AXIFERT lines, the characterization lies mainly in the organic matrix, very rich in amino acids, mostly free, with a good supply of organic Nitrogen and a high physical stability. The NEWFERSTIM and AXIFERT line is effective because this organic liquid matrix is able to exert an activity of biostimulant and physiological support on the plant, free amino acids and peptides, are able to form chelates and complexes with salts and metals, of natural and easy assimilation.
The line NEWFERSTIM and AXIFERT linked to the technique of fertigation represents an optimal way to make the most of fertilization resources, especially if thought in terms of sustainability of the plant, with or without intensive forcing; this opportunity is not the only one that can be ascribed to the organic matrix. A further relevant effect is, for example, the activation of specific enzymes; by facilitating the incorporation of Nitrogen into proteins, these facilitate the rationalization of nitrogen fertilization and reduce the risk of nitrate accumulation in leaves and fruits.

ADVANTAGES

What advantages do NEWFERSTIM liquid fertilizers obtain from having an organic matrix very rich in amino acids?

• The first advantage (thanks to the free amino acids) is that they are quickly absorbed and transported in the plant to stimulate some functions of the vegetative metabolism, such as: growth, flower and fruit development, higher pollen fertility, higher fruit set, higher resistance to pathogens and environmental adversities, therefore less stress and a better vegetative and productive balance of the crops.
• The second advantage, linked to the presence of polypeptides, is that they are used as chelating agent of macro, meso and micro elements. The chelation occurs in two or more points and the chelator wraps the ion with bonds that are extraordinarily stable and soluble in a wide range of pH. The formation of the chelate increases the bioavailability of the nutrients, with extremely positive repercussions on the root uptake.
• The amino acid of the liquid organo-mineral, simulating the natural process of selective root uptake, acts as a carrier for the chelated ions, making their transport easier and more accessible in the plant and subsequently in the sites where they will have to operate. Several scientific experiences show that some types of amino acids operate a carrier effect, of high nutrient transport.
