jordkemi
Jordkemi, or soil chemistry, is the branch of science that studies the chemical properties and processes of soils. It examines how minerals, organic matter, water, and gases interact to control the availability of nutrients to plants and the fate of contaminants. The discipline integrates aspects of inorganic chemistry, organic chemistry, and mineralogy to explain soil fertility, structure, and environmental behavior.
Key concepts include soil solution chemistry, pH and acidity, and cation exchange capacity (CEC) with base saturation.
Common methods involve soil sampling and laboratory analysis to determine pH, exchangeable cations, available phosphorus (via
Applications of jordkemi include guiding fertilizer recommendations, optimizing crop production, and assessing environmental risks such as
Jordkemi intersects with soil science, agronomy, environmental science, and geochemistry. It is taught in universities as
