Soil Science

Soil science studies soil as a medium in which plants grow. Like all sciences, it divides its subject into sections that can be studied separately and for their effect on each other. The ways soil scientists look at soil include:

Soil Components The different types of materials that make up soil.

Soil texture and structure The size and aggregation of the particles that make up soil.

Other soil physical dimensions Such as its temperature, color, depth, etc.

Soil chemistry This includes the acidity or alkalinity, the plant nutrients it contains, and the interactions between different chemicals that make up the complex mixture that is soil.

Soil orders This system classifies soils with similar features into orders and families. This is a taxonomy of soils.

Soil life The most important of these are microscopic bacteria and fungi, but soil life also includes earthworms, nematodes, insects and mites, and larger animals.
