What is coated compound fertilizer? A detailed explanation of this new type of compound fertilizer
Coated compound fertilizer is a plant nutrient complex made with granular soluble nitrogen fertilizer as the core, calcium and magnesium phosphate fertilizer as the coating layer, with potassium fertilizer, micronutrients and their chelating agents, pesticides, herbicides and microorganisms added into the coating layer, and nitrogen-phosphorus slurry and inorganic acid compound fertilizer as binders, produced by a special coating method.

Coated compound fertilizer is a plant nutrient complex made with granular soluble nitrogen fertilizer as the core, calcium and magnesium phosphate fertilizer as the coating layer, with potassium fertilizer, micronutrients and their chelating agents, pesticides, herbicides and microorganisms added into the coating layer, and nitrogen-phosphorus slurry and inorganic acid compound fertilizer as binders, produced by a special coating method. Its obvious characteristics are scientific formula and high utilization rate, controllable release, combining slow release and long-lasting effect with quick dissolution, high efficiency and fast action, and it is highly targeted, widely adaptable and convenient to use, making it the outstanding product in the current compound fertilizer industry. In particular, the eco-friendly coated compound fertilizer that has been developed can greatly reduce soil pollution, further improve fertilizer efficiency and achieve controlled release, and is the newest fertilizer of the 21st century. At present, the main products can be divided into three major series.
1. Slow-release long-lasting coated fertilizer: widely suitable for fertilizing fruit trees and various crops, with high fertilizer utilization rate and remarkable yield-increasing effect. According to follow-up surveys by the Chinese Academy of Agricultural Sciences, compared with compound fertilizer of the same content, the utilization rates of nitrogen, phosphorus and potassium increased by 7.24%, 7.2% and 10.4% respectively.
2. High-efficiency potassium sulfate topdressing: its main characteristics are being flammable, easily soluble, leaving no residue and allowing controlled fertilization, and it takes effect immediately 3 days after topdressing. It is mainly suitable for fertilizing vegetables at the middle and late stages.
3. Eco-friendly controllable coated compound fertilizer: its main characteristics are reducing soil pollution, reducing the number of fertilizations, improving fertilizer efficiency and having a remarkable yield-increasing effect.
