Potassium humate is generated by the acidic groups of humic acid from peat, lignite or weathered coal reacted with potassium hydroxide. It mainly includes potassium humate made with dry process and wet process, and it is regarded as a new type of potash fertilizer. Two kinds of production process of potassium humate and the application as the main materials for new type fertilizers was summarized. Potassium humate with dry process that could be widely used in microbial compound fertilizer, organic-inorganic compound fertilizer etc., using as base fertilizer application. On the other hand, water soluble potassium humate with wet process was very important material of potassium in water soluble fertilizer. As the new type of potassium, potassium fertilizer humate has the functions of soil improvement, stimulating crop root development, avoiding potassium fixation and improving crop yield and quality.

Potassium humate can promote seed germination, known as natural root powder, so it has a good promoting effect on seed immersion transplantation. Potassium humate can promote seed germination in a very short time, called natural root powder, especially for those crops with low survival rates have a good effect.

The effect of potassium humate on crop body greatly increases the resistance of plants, reduces the impact of pests and diseases and drought and flood disasters on crops. Potassium humate can regulate the reduction of leaf stomatal opening and water transpiration, mobilize the absorption of potassium ion Chemicalbook by plants, promote metabolism, promote the intensity of respiration and photosynthesis, promote the activity of plant enzymes, and improve the drought resistance of crops, thus increasing the water saving capacity by 30%. Improve plant resistance to drought, cold, disease and insect pests.
