Difference between potassium-containing compound fertilizer and potassium humate

1. Compound fertilizer refers to chemical fertilizer containing two or more nutrient elements. Compound fertilizer has the advantages of high nutrient content, few by-products and good physical properties, which plays a very important role in balancing fertilization, improving fertilizer utilization rate and promoting high and stable yield of crops.

2. Potassium humate is a heterogeneous aromatic hydroxycarboxylic acid salt, which is a black particle or a powdery solid. It is the product of selective extraction from lignite and reaction with KOH liquid. It is alkaline when dissolved in water and contains active groups such as carboxyl group and phenolic hydroxyl group. High-quality potassium humate is an efficient organic potassium fertilizer, which does not contain potassium oxide, because humic acid is a bioactive preparation, which can increase the content of available potassium in soil, reduce the loss and fixation of potassium, improve the absorption and utilization rate of potassium by crops, and also have the functions of improving soil, promoting crop growth, improving crop stress resistance, improving crop quality and protecting agricultural ecological environment. It can be mixed with urea, phosphate fertilizer, potash fertilizer and trace elements. Can be made into high-efficiency multifunctional compound fertilizer; In addition, potassium humate can also be used as a treatment agent for petroleum drilling fluid, which mainly plays a role in preventing wellbore collapse.
