Physical Properties of Soil

This set of flashcards covers the key concepts related to the physical properties of soil, including texture, structure, porosity, aeration, organic matter, mineral matter, temperature, and organisms.

Soil Texture

Refers to the proportion of sand, silt, and clay particles in the soil.

Soil Structure

The arrangement of soil particles into aggregates or crumbs.

Soil Porosity

The amount of pore space between soil particles.

Soil Aeration

The exchange of gases (oxygen and carbon dioxide) between the soil and atmosphere.

Organic Matter

Decomposed plant and animal remains (humus) that improve soil structure, increase water-holding capacity, and supply nutrients.

Mineral Matter

Inorganic particles derived from weathered rocks that provide essential nutrients and form the bulk of soil particles.

Soil Temperature

The degree of warmth in the soil, affecting seed germination and microbial activity.

Soil Organisms

Living organisms in soil such as earthworms, bacteria, and fungi that contribute to soil health.
