L-Aspartic Acid for Agriculture
CAS No：34345-47-6
Product performance
PASP is a water-soluble polymer synthesized by artificial bionics. It is phosphorus-free, non-toxic, pollution-free and fully biodegradable. It is an internationally recognized "green chemical". Polyaspartic acid has strong chelation, dispersion, adsorption and other functions due to its structural characteristics of active groups such as peptide bonds and carboxyl groups, and has excellent compatibility. Polyaspartic acid as a fertilizer synergist can strengthen the comprehensive absorption of nitrogen, phosphorus, potassium and trace elements by crops, so as to improve the utilization rate of fertilizer, reduce the use of fertilizer and increase crop yield.

Purpose
As a fertilizer synergist, agricultural polyaspartic acid is the raw material of polypeptide fertilizer, water-soluble fertilizer and synergetic fertilizer. It can promote the absorption of nutrients by crops such as grain, vegetables, melons and fruits, flowers and so on. At the same time, it can improve the efficacy when used together with pesticides. The research and application results at home and abroad show that polyaspartic acid is indeed effective as a plant nutrient absorption promoter, which is suitable for a variety of plants and soils. Its main characteristics are as follows when used in combination with chemical
Fertilizer
After using polyaspartic acid, the nitrogen, phosphorus and potassium nutrients in the soil maintain high activity in all periods. The utilization rate of nitrogen fertilizer can be increased by 15.3%, the utilization rate of phosphorus fertilizer can be increased by 8.3%, and the utilization rate of potassium fertilizer can be increased by 10.7%, so as to reduce the loss of chemical fertilizer, reduce the amount of chemical fertilizer by 20%, and increase the yield by 10-30%. The economic benefits are obvious.
Polyaspartic acid can promote the absorption of trace elements such as iron, zinc and manganese in crops, which has a synergistic effect. The content of trace elements in crops treated with polyaspartic acid is 3-4 times higher than that of contrast crops, and the content of protein and sugar is also increased.
Polyaspartic acid has the function of anti stress protease, which can effectively promote the development of crop roots, increase the absorption area of roots, improve the ability of crops to absorb nutrients, and enhance the ability of crops to resist lodging, drought, cold and disease.
Polyaspartate can be targeted to supplement the demand for trace elements in all stages of crop growth, improve the fruit setting rate and crop quality, promote the early maturity of crops for 7-10 days, and extend the harvest period for 10-15 days.
Packaging and storage
