Parameters

Humic acid is divided into four types: fulvic acid, palm humic acid, black humic acid and green humic acid.

 

Main functions: The five major functions of humic acid in agriculture include improving soil, increasing fertilizer efficiency, stimulating growth, enhancing stress resistance and improving quality. It guides the application and progress of humic acid in agriculture.

 

A.  The use of humic acid can change the physical and chemical properties of soil with high salt content, strong alkalinity, highly dispersed soil particles and poor soil structure, promote the formation of soil aggregates and make them in a good state, thus creating good conditions for the growth and development of plant roots.

B.  The application of humic acid can loosen the soil in the cultivated layer, destroy the accumulation of salt, reduce the salt content of the topsoil, play a role of salt isolation, increase the emergence rate, reduce weak and dead seedlings, and make plants grow healthily.

C.  The humic acid has higher cation conversion capacity, which is more than 10 times higher than that of common soil. After being applied into soil, the adsorption capacity of anion in soil was significantly improved, and the salt content in surface layer was decreased.

D.  The pH value of saline alkali soil, especially alkaline soil, is over 9.0, which will directly harm the growth of crops and even cause death. In addition, the high pH value also affects the availability of phosphorus, iron, manganese, boron, zinc and other nutrients in the soil. The pH value of humic acid is 6.8, which can neutralize alkalinity, reduce the harm of alkalinity to soil and plants, improve the low yield saline alkali land, and create good soil conditions for the growth of crop seedlings.
