Geochemistry of Soil Amendments

Geochemistry of soil amendments refers to the study of the chemical composition and properties of materials added to soil to enhance its fertility and structure, focusing on how these amendments interact with soil components and affect nutrient availability, pH, and microbial activity. This field examines the elemental and molecular transformations that occur when soil amendments are applied, influencing soil health and plant growth.

Key Terms

Soil pH
A measure of the acidity or alkalinity of soil, affecting nutrient availability.

Example: A pH of 6.5 is ideal for most crops.

Organic matter
Decomposed plant and animal materials that improve soil structure and fertility.

Example: Compost is a common source of organic matter.

Nutrient cycling
The movement and exchange of nutrients in the soil-plant system.

Example: Nitrogen cycling involves bacteria converting nitrogen into forms usable by plants.

Soil structure
The arrangement of soil particles and the spaces between them, affecting water retention.

Example: Well-structured soil allows for better root growth.

Fertilizers
Substances added to soil to supply essential nutrients for plant growth.

Example: Nitrogen fertilizers boost plant growth but must be used carefully.

Compost
Decomposed organic material used as a soil amendment to enhance fertility.

Example: Adding compost improves soil texture and nutrient content.
