Agricultural
chemistry is the study of chemistry, especially organic chemistry and
biochemistry, as they relate to agriculture—agricultural production, the
processing of raw products into foods and beverages, and environmental
monitoring and remediation.
This note covers the following topics: Soil- A Three Phase System, The Solid Phase- Surfaces In Soil and
Their Reactivity, The Solution Phase Review of Solution Phase Chemistry and
Discussion of Solutions in The Soil Matrix, Interaction Between Solid and
Solution Phase- General Solubility Relationships, Carbonate Equilibria and
Solubility, Cation Exchange Reactions in Colloidal Systems, Soil Buffering and
Soil pH Redox Reactions in Soil Systems.
Agricultural chemicals are used for insecticide or for
herbicide; almost of which have toxicity to human and live stocks. It may also
include synthetic fertilizers, hormones and other chemical growth agents, and
