Potassium humate is the potassium salt of humic acid. It is manufactured commercially by alkaline extraction of brown coal (lignite) Leonardite to be used mainly as a soil conditioner. The extraction is performed in water with the addition of potassium hydroxide (KOH), sequestering agents and hydrotropic surfactants. Heat is used to increase the solubility of humic acids and hence more potassium humate can be extracted.
Potassium humate is a highly effective organic fertilizer, because humic acid is a high active agent, can increase available potassium in soil, reduce the loss and fixation of potassium, increase crop potassium absorption and utilization,also can hold the nitrogen and slow release,unclock the phosphorus inside the soil ,chelate the micro elements, improve the soil structure to increase its water holding capability and create good environment for microbial group ,which will also help to improve the soil structure.Accordingly the soil fertility will be greatly increased and increased plants growth and harvest and its fruits quality.
