Geochemical Approaches to Soil Health

Geochemical approaches to soil health refer to the analysis and interpretation of the chemical properties and processes within soil ecosystems to assess its fertility, nutrient availability, and overall ecological function. These methods often involve the measurement of soil pH, organic matter content, nutrient concentrations, and the presence of contaminants, providing insights into soil quality and sustainability.

Key Terms

Soil Composition
The makeup of soil, including minerals, organic matter, water, and air.

Example: The soil composition affects its fertility and structure.

Nutrient Cycling
The process by which nutrients are recycled in the ecosystem.

Example: Nutrient cycling ensures that plants receive essential elements.

pH Level
A measure of how acidic or alkaline a substance is, on a scale of 0 to 14.

Example: A pH of 7 is neutral, while below 7 is acidic.

Contaminants
Substances that pollute or degrade the quality of soil.

Example: Heavy metals are common soil contaminants.

Macronutrients
Nutrients required in large amounts for plant growth, such as nitrogen, phosphorus, and potassium.

Example: Nitrogen is a key macronutrient for leafy plant growth.

Micronutrients
Nutrients needed in smaller amounts, such as iron and zinc.

Example: Zinc is essential for plant enzyme function.
