What is amino acid chelate organic fertilizer?
Amino acid chelates are compounds with a cyclic structure formed by the coordinated reaction of one or more amino acid (small peptide) groups with metal ions. The chelated organic trace elements have a dual effect of meeting the body’s trace element requirements and supplementing the amino acids.
Why should we use amino acid chelate fertilizer?
There are as many as 17 nutrients necessary for crop growth, divided into large, medium and micronutrients. The bulk elements include carbon, hydrogen, oxygen, nitrogen, phosphorus and potassium, the medium elements include calcium, magnesium and sulphur, and the trace elements include iron, copper, zinc, manganese, molybdenum, boron, nickel and chlorine. With the increase in modern agricultural production and the massive use of nitrogen, phosphorus and potassium fertilisers, there is an increasing trend of micronutrient deficiencies in the soil.
In many parts of the world, micronutrients are still simple inorganic salts and their availability is somewhat limited. Inorganic micronutrients lose much of their activity when applied to the soil and are poorly absorbed by plants, even when balanced fertilizers are used.
Amino acid chelated micronutrients are soluble organic fertilisers that can be absorbed directly by the crop, improving the utilisation and uptake rate of the fertiliser. The amino acids themselves as soluble organic fertilizers stimulate plant growth and are directly absorbed by the crop without photosynthesis, improving the photosynthesis of the crop. After chelating the micronutrients, it can also improve the absorption and utilisation of the micronutrients and protect the metal ions from sending side effects with other substances, making them also well absorbed and utilised by the crop. It also improves the utilisation rate of fertilisers such as NPK.
The advantages of amino acid organic fertilizers.
More stable structure, less susceptible to insoluble material formation
Amino acids form stable five- or six-membered ring complexes with metal ions, which are encapsulated within the ring structure by ionic and coordination bonds, allowing the intramolecular charge to become neutral and thus less likely to combine with other substances to form insoluble substances and be adsorbed by colloids.
Reduced antagonism between different ions
There is a complex antagonism between trace elements, such as iron and zinc, copper and Mo, etc. After chelating calcium, magnesium, iron, manganese, boron, zinc, copper, molybdenum and other trace elements, amino acid chelate is purely organic and fully soluble in water. It can meet the absorption of various elements of the crop, prevent the symptoms of deficiency, and when mixed with other fertilisers, it can be used without antagonistic chemical reactions and does not reduce the fertilising effect of other fertilisers, and can improve the absorption and utilisation rate of other fertilisers, with a utilisation rate of 55-60%. It also prevents the occurrence of physiological diseases in crops due to elemental deficiencies.
Promoting root development
Amino acid chelated trace elements have more balanced nutrition, are not easily fixed in the soil, are fully water soluble and can be well absorbed and used by the crop roots.
Amino acid chelated organic fertilizer can improve the soil micro-domain environment, improve the soil and enhance the vitality of soil microorganisms, thus promoting the absorption of soil minerals and nutrients by plant roots and promoting root growth. It has a slow and controlled release effect on nitrogen fertilizers, an activating function on phosphorus and potassium elements, and can improve the effectiveness of medium and trace elements such as calcium, magnesium, zinc and manganese in the soil.
Improved fertilizer efficiency and increased yields
Amino acid chelated fertiliser promotes photosynthesis and the complementary, balanced and coordinated function of various nutrients in crops and promotes root development. The comprehensive utilisation rate of nitrogen, phosphorus and potassium is increased by 20%-35% and the fertilisation period is more than doubled compared with ordinary fertilisers. Under the same nutrient content fertilisation conditions, it can increase the yield of field crops by 15%-20% and that of cash crops by 15%-30%.
Enhances the crop’s resistance to drought, high temperature, low temperature, and salinity and the ability to resist collapse. It also enhances the activity of various enzymes in plants, decomposes and removes pathogenic bacteria, improves crop resistance to pests and diseases, and significantly reduces morbidity and pesticide use.
Faster uptake and improved utilisation
Inorganic elements penetrate the cell membrane and are absorbed by the body, requiring carrier molecules to wrap the metal ions and form a lipid-soluble complex outside the cell membrane in order for the cations to cross the cell membrane; some studies suggest that metal ions located in the centre of five or six-membered ring chelates can pass through the brush border of the small intestinal villi, and that all amino acid chelates can be absorbed in the form of amino acids or peptides.
Once the amino acid chelates of trace elements enter the body, the trace elements chelated by the corresponding amino acids can be transported directly to the specific target tissues and enzyme systems according to the proportion and quantity of amino acids required by different tissues and enzyme systems, and the trace elements can be released through the action of enzymes and tissues to meet the needs of the body, thus eliminating the biochemical processes required for the absorption of inorganic elements and thus increasing the trace element This eliminates the biochemical processes required for the uptake of inorganic elements, thus increasing trace element utilisation.
Dual-action nutrition and reduced toxicity
Amino acid chelates contain amino acids and metal elements, both of which are directly available to the plant. It has been found that the chelate significantly improves the reverse osmosis caused by high concentrations of metal ions, which can lead to root burning and seedling death. Chelates also significantly improve the irritation of trace elements and allow for better crop uptake.
As a soluble organic fertiliser, amino acids can be absorbed directly by plants without photosynthesis, and chelating different micronutrients can meet the micronutrient requirements of different plants. The organic nitrogen is supplemented with different organic trace elements at the same time.
