1. Stimulating effect on plant root growth.
The stimulating effect of mineral humic acid on plant root growth is the initial driving force for its promoting effect on plant growth.
The stimulating effect of mineral humic acid on plant root growth is mainly reflected in promoting the increase in root length and root number. After application, it can increase plant biochemical activity, produce an auxin-like effect on the root system, and stimulate plant endogenous cell kinins and plant The increase in auxin causes changes in the permeability of the cytoplasmic membrane, promotes plant protein synthesis and cell growth, thereby promoting plant root growth and increase in yield.
2. Promote the absorption of nutrients by plant roots
On the one hand, mineral humic acid can promote the expression of genes related to nitrate absorption and assimilation in plant roots.
On the other hand, mineral humic acid can stimulate plants’ absorption of nitrate by regulating the internal environment of plant roots.
Finally, mineral humic acid can also be absorbed by plants as nutrients.
