As a water-soluble polymeric amino acid, polyaspartic acid PASP has the characteristics of phosphorus-free, non-toxic, pollution-free and degradable. It is a representative product of “green chemicals” in the world.
The amide group and free carboxyl group on the main chain endow polyaspartic acid with strong chelating, adsorption, dispersion, moisturizing and other functions.
- Widely use as a polypeptide additive for polypeptide urea and polypeptide compound fertilizer;
- Corrosion and scale inhibitors for reverse osmosis water, oil field reinjection water, metal cutting fluid, etc.;
- Dispersant in papermaking, printing and dyeing, washing and other industries.
Polyaspartic acid is effective as a fertilizer synergist and is suitable for a variety of crops and soils.
The effects of polyaspartic acid PASP and fertilizers are mainly manifested in:
1. Improve the utilization rate of fertilizer
Reduce the loss of chemical fertilizers, activate nutrient elements, and improve the utilization rate of chemical fertilizers.
2. Promote the absorption of trace elements.
Polyaspartic acid (PASP) contains carboxyl groups, which can quickly combine with nutrient ions and exchange with H+ secreted by crop roots to complete the process of nutrient ions being absorbed by crops. The aspartic acid monomer itself can form a chelate with divalent ions, making the medium and trace elements Mg2+, Fe2+, Zn2+, etc. into an easily absorbable state, so the crops have a good taste and storage resistance, and the yield is high.
3. Promote growth and increase production
Experiments at home and abroad have proved that the mixed use of polyaspartic acid and chemical fertilizers for different crops reflects the same results, that is, the yield increases by about 9-25%, and the economic benefits are significantly improved.
4. Polyaspartic acid PASP can improve crop quality
By promoting the absorption of medium and trace elements, polyaspartic acid achieves a coordinated supply of crop nutrients and improves crop quality; it avoids malformed fruits, bald tips, cracked fruits and poor coloring caused by malnutrition and hormone use.
5. Promote root growth and enhance stress resistance
Polyaspartic acid is not a hormone, but it can effectively promote the development of root system, make it grow longer roots and more root hairs, increase the surface area of roots, improve the ability of crops to absorb nutrients, and enhance the resistance of crops to lodging and drought , cold resistance, disease resistance and other stress resistance.
6. Green and environmental protection, improve the soil
- Polyaspartic acid itself is an environmentally friendly product that is non-polluting, degradable, hormone-free, heavy metal-free, and without any negative effects.
- Polyaspartic acid can reduce the adverse impact of excessive fertilization on the environment, and can also activate the fixed nutrients in the soil, which not only improves the fertilizer utilization rate, but also improves the soil quality.
Dosage and method of polyaspartic acid PASP:
It is recommended to add at least 100g of polyaspartic acid per mu. Mix polyaspartic acid and fertilizer evenly or dissolve it in water before applying.
