There is no better way to enhance the economics of farming, than to build soil humus and enhance the natural processes, such as microbial activity, which can be sustained over a long period of life. Potassium humates derived from lignite brown coal are alkaline, rich in carboxylic and phenolic groups, aromatic in nature and provide favourable conditions for biological activity, chemical reactions and physical improvement of soil. Accumulation level of natural humic acids like potassium humate has shown to reduce the need for commercial fertilizers because it improves fertilizer efficiency. The utilization of humic acid has been found to reduce the leaching of fertilizers and pesticides into aquifer and surface waters. By using humic acids, growers will gradually reduce application macro and micronutrients fertilizers application with addition to the improvement of overall crop yields and quality.
Potassium humate is the salt of humic acid, derived from lignite brown coal and rich in carboxylic and phenolic groups
Humic acid influence the plant growth both directly and indirectly. The indirect effect of humic acid improves physical, chemical and biological condition of soil
Its direct effects attributed due to its metabolic activity in plant growth
Potassium humate enhance soil health as well as environment quality during crop cultivation
