Chemical fertilizers refer to fertilizers produced by chemical methods or mining minerals, and are also called inorganic fertilizers, including nitrogen fertilizers, phosphate fertilizers, potash fertilizers, micro-fertilizers, compound fertilizers, etc. They have the following common characteristics: simple composition, high nutrient content; fast fertilizer effect and strong fertilizer; some fertilizers have acid-base reaction; generally they do not contain organic matter and have no effect on improving soil fertility.
Chemical fertilizer is a compound mixture made from various raw materials after reasonable adjustment and processing. After the ultrafine treatment, the surface area of the particles is increased, and their dispersibility, adsorption capacity, surface activity, etc. have comprehensive changes, which are of great significance for improving fertilizer efficiency and saving dosage.
