Key Terms

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

Example: Soil composition affects its ability to retain nutrients.

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

Example: Nutrient cycling is vital for maintaining soil fertility.

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

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

Soil Fertility
The ability of soil to provide essential nutrients to plants.

Example: Soil fertility can be improved with organic amendments.

Organic Matter
Decomposed plant and animal residues that enrich soil.

Example: Organic matter improves soil structure and nutrient retention.

Microbial Activity
The activity of microorganisms in the soil that aids in nutrient cycling.

Example: High microbial activity indicates healthy soil.
