Green and environmentally friendly fertilizer enhancer--polyaspartic acid PASP

1. Research on fertilizer synergistic performance

Polyaspartic acid can increase the utilization rate of nitrogen fertilizer by 60.3%, phosphorus fertilizer by 5.3%, and potash fertilizer by 16.7%. Objectively speaking, the yield increase effect on relatively barren land is better than that on fertile land. The yield increase effect on relatively fertile land generally does not exceed 20%, mostly around 5-15%, but the quality is significantly improved; the yield increase effect on greenhouse vegetables is better than that on field grain crops; the yield increase of leafy vegetables can generally be maintained at 10-20%, and no deficiency symptoms occur.

2. Yield increase and growth promotion effect

3. Improve crop quality

PASP achieves the coordinated supply of crop nutrients and improves crop quality by promoting the absorption of trace elements; it avoids deformed fruits, bald tips, cracked fruits and poor coloring caused by malnutrition and the use of hormones.

After the soil is treated with PASP, the effectiveness of nutrients such as nitrogen, phosphorus, potassium, calcium, magnesium, and trace elements such as boron, molybdenum, and manganese are significantly improved.

PASP can inhibit the volatilization of nitrogen fertilizer applied to the soil as ammonia nitrogen; it can reduce the fixation and deposition of phosphorus fertilizer in the soil. By investigating the effect of PASP on crop quality, it was found that the content of vitamin C and soluble sugar increased to varying degrees when PASP was applied to vegetables, fruits, and melons; the content of nitrogen and phosphorus in vegetables increased; the oil content of rapeseed increased; the protein content and potassium content of rice increased, which played a role in improving and enhancing crop quality.

4. Promote root growth and enhance stress resistance.

Polyaspartic acid is not a hormone, but it can effectively promote the development of crop roots, make them grow longer roots and more root hairs, increase the surface area of the roots, improve the ability of crops to absorb nutrients, and enhance the resistance of crops to lodging, drought, cold, disease, and other stresses.

5. Green and environmentally friendly, improve soil.

First, polyaspartic acid itself is a non-toxic, non-polluting, degradable, hormone-free, heavy metal-free, and environmentally friendly product with no side effects.

Second, polyaspartic acid can reduce the adverse effects of excessive fertilization on the environment, and can also activate the fixed nutrient elements in the soil, which not only improves the fertilizer utilization rate, but also improves the soil quality.

Polyaspartic acid treatment can improve soil nutrients, which is beneficial to the growth and development of subsequent crops, and manifests as a certain aftereffect. The bulk density of soil treated with polyaspartic acid is lower than that without application, with an average decrease of 0.0595g/cm3, a decrease of 3.73 percentage points. The physical clay particles treated with polyaspartic acid increased by an average of 1.725 percentage points compared with those without application. The application of polyaspartic acid can increase the content of physical clay particles in the soil and improve the soil particle structure.
