FERTILISERS; MANUFACTURE THEREOF

Description

C05 covers the chemical composition, formulation, and manufacturing processes of fertilizing materials and soil amendments. This includes synthetic fertilizers (nitrogen, phosphorus, potassium compounds), organic fertilizers, mixed fertilizer compositions, and methods for their production or treatment. The class extends to conditioning and stabilization of fertilizers, as well as testing and quality control methods related to fertilizer performance. Adjacent classes handle related subjects such as compost (A23G, C05F), agricultural soil improvement techniques beyond chemical fertilization, and the use of specific chemical compounds in isolation when not formulated as fertilizers.
