NITROGENOUS FERTILISERS

Introduced: September 1968

Classification Context

Section:
CHEMISTRY; METALLURGY
Class:
FERTILISERS; MANUFACTURE THEREOF
Subclass:
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.

Scope Notes

Glossary: Fertiliser (fertiliser material) Natural or artificial substance containing the chemical elements that improve growth and productiveness of plants. Nitrogenous fertiliser – see also "Special rules" above when more than one element present Fertiliser materials, natural or synthesized, containing nitrogen available for fixation by vegetation, such as potassium nitrate, KNO3, or ammonium nitrate, NH4NO3 | Limiting references: PHOSPHATIC FERTILISERS INORGANIC FERTILISERS NOT COVERED BY SUBCLASSES , ; FERTILISERS PRODUCING CARBON DIOXIDE ORGANIC FERTILISERS NOT COVERED BY SUBCLASSES , , e.g. FERTILISERS FROM WASTE OR REFUSE
