Soil Characteristics

Soil is much more than just dirt beneath our feet. It’s a complex mixture of minerals, organic matter, and living organisms that supports plant growth and provides a habitat for microorganisms and animals.

It consists of both organic and inorganic materials. Organic materials come from decayed plants and animals, while inorganic components include rock particles, minerals, water, and air.

Soil composition varies from place to place, depending on the types of rocks and organisms in the area.

Scientists classify soil based on its texture, which depends on the size of its particles. Soil particles are of three main types: sand, silt, and clay.

Sandy soil has large particles, making it loose and drain well. That’s why beaches are made of sand.

Silty soil has medium-sized particles, making it soft and smooth. It also holds moisture better than sandy soil.

Clay soil has very small, tightly packed particles, which hold water well but make it harder for plant roots to spread.

A good balance of sand, silt, and clay creates loam, which is ideal for growing plants because it retains moisture while allowing proper drainage.
