NITROGENOUS FERTILISERS

Description

C05C covers nitrogenous fertiliser compositions and their manufacturing processes. This subclass includes ammonia-based fertilisers, nitrate salts, urea compounds, ammonium salts, and complex fertilisers containing nitrogen as a primary nutrient. Manufacturing methods for nitrogen fertilisation products, such as the synthesis of ammonia, nitric acid production, and granulation or prilling of nitrogen-containing compounds, fall within this classification. Adjacent subclasses C05A and C05B address organic fertilisers and phosphatic/potassic fertilisers respectively, while C05F and C05G cover compound fertilisers and methods not specific to single nutrient types.
