Difinition of amino acid fertilizer
amino acid fertilizer is a kind of quick acting fertilizer that can be directly absorbed and utilized by crops
How does Amino acid fertilizer increase nutrients utilization rate of nitrogen potassium phosphorus and secondary or trace essential elements ?
1. Improve the utilization rate of nitrogen fertilizer
Amino acids are rich in acid functional group carboxyl ,in which hydrogen ion can be easily “squeezed out “by ammonium ions in the soil,and when ammonium ions occupy hydrogen ion ‘s position, it decrease nitrogen’s leaching thus fix nitrogen in the soil. The fixed nitrogen combined with amino acids together are more easier accessible to plants,directly absorbed by plants ,therefore improve the utilization rate of nitrogen fertilizer
2. Improve the utilization rate of phosphate fertilizer
Amino acids could activate phophatase activity in soil ,promote its Organic phosphorus compounds ( OPCs),decompose and convert them into inorganic phosphorus which is accessible to plants.By this method , it not only activate phosphorus in soil ,but also promote its movement to roots, thus improved plants absorption to phosphorus and its utilization rate.
3. Improve the utilization rate of potassium fertilizer
Acidic functional group ,carboxyl group could absorb and store potassium ion, prevent the loss of potassium fertilizer when comes to sand soil or soil with strong leachability.
In addition, it also can dissolve silicate, potassium feldspar etc potassium bearing minerals , gradually decompose them and release potassium , thus improve quick-acting potassium content and its utilization rate.
4. Improve the utilization rate of secondary or trace essential elements
Glycine,proline,Histidine,Methionine are natural metal chelating agents ,they can chelate with insoluble medium and trace elements, generate chelates which are easy to adsorb and excellent solubility ,meanwhile promote the movements of trace elements upwards and make roots accessible to more metal elements ,thus improved utilization rate of secondary or trace essential elements
