The action of humic acid is divided into three aspects: physical action, chemical action, and biological action.
The composition and properties of humic acid determine its broad application prospect in environmental protection.
There are about 4 trillion tons of humus (humic substance) on the earth and it is an important part of the soil. Humic acid is the most active component of soil humus, which plays a key role in the soil's formation, properties, and fertility.
Humic acid can increase the yield of all kinds of crops, but the relationship between humic acid and crops is complicated, which is related to the effect size of humic acid stimulation and the sensitivity of crops.
The synergistic effect of humic acid on NPK
Crops have different reactions to humic acid series products in different growth periods and the early growth effect of general crops is obvious.
Humic acid based products are suitable for all kinds of soil, but the effect of increase yield is different under different soil conditions.
Humic acid based products have a better obvious effect on root crops such as turnip, potato, and sweet potato.
