ORGANIC FERTILISERS NOT COVERED BY SUBCLASSES C05B, C05C, e.g. FERTILISERS FROM WASTE OR REFUSE

Introduced: September 1968

Description

C05F encompasses organic fertilisers derived from waste materials, refuse, and other organic sources not classified elsewhere within the fertiliser categories. This subclass covers technologies for processing and converting organic waste streams—such as compost, sewage sludge, animal manure, and industrial organic byproducts—into soil amendments and plant nutrients. The classification includes methods for treating, stabilising, and preparing these materials to improve their agronomic value and safety for agricultural application.
