Effects of potassium humate on soil
The Hydroxyl groups and carboxyl groups in potassium humate react easily with calcium ions in soil. Then form the aggregate structure of soil through the physiological action of plant roots.
When the aggregate structure of soil becomes better, the bulk density decreases and the voidage increases. So it has good permeability. Because the color of potassium humate is dark, it is beneficial to the absorption of solar heat energy. When humic acid is decomposed by microorganisms, it releases heat. Especially when crop seedlings are unearthed in early spring season, it can increase ground temperature and play a role in resistance to spring cold.
