The raw materials for the production of compound fertilizers mainly involve compounds of nitrogen, phosphorus, potassium and other elements, which are widely used in the chemical industry. Therefore, the upstream and downstream related products of compound fertilizer are also quite rich.

Upstream Associated Products

1. Nitrogen Source: The main nitrogen sources of compound fertilizers include urea, ammonium nitrate, ammonium sulfate, etc. These nitrogen source compounds are mainly produced by chemical synthesis methods, and their raw materials involve natural resources such as natural gas, coal, and gypsum.
2. Phosphorus sources: Phosphorus is an important element in compound fertilizers. The main phosphorus sources include monoammonium phosphate, diammonium phosphate, calcium phosphate, etc. These phosphorus compounds are typically produced by acidolysis or pyrolysis of phosphate rock.
3. potassium source: potassium source mainly includes potassium chloride, potassium sulfate and so on. Their production mainly depends on the extraction and processing of potassium ore.

downstream associated products

1. Agricultural compound fertilizer: compound fertilizer can be directly used as agricultural fertilizer to improve soil fertility and promote crop growth. Different types and ratios of compound fertilizers can be customized for different crops and soil conditions.
2. Animal feed additives: nitrogen, phosphorus, potassium and other elements in compound fertilizers can also be used as animal feed additives to supplement the nutrients needed for animal growth.
3. Industrial chemicals: Some compound fertilizers can be used as raw materials for industrial chemicals, such as for the production of detergents and food additives.

To sum up, the upstream and downstream related products of compound fertilizers are quite rich, involving many fields, such as agriculture, chemical industry, animal feed, etc. The production and application of these related products have further promoted the development and technological progress of the compound fertilizer industry.
