Mechanism of action:

1. As a high molecular polymer, polyaspartic acid can activate the soil, has a strong ability to chelate ions, deprive metal ions in phosphate, and promote the absorption of phosphorus by plants.

2. Polyaspartic acid substances can participate in the plant's tricarboxylic acid cycle, which is completely absorbed and utilized by plants, promotes plant growth, and can be degraded and absorbed without residual harm.

3. It can promote the growth of plant roots, and potassium can improve plant resistance to stress (improve drought and cold resistance).

4. The polyaspartic acid substance itself is a scale inhibitor and dispersant, which can prevent the drip irrigation pipeline from scaling, alleviate soil hardening and salinization, and improve the soil environment.
