Types of Soil

Soil is a mixture of minerals, air, water, broken pieces of rocks, clay, and the remains of dead plants and animals. It also has many insectsand earthworms that live in it

There are three main types of soil depending on:

• size

• texture of the soil particles

Sand

• Rough and Dry

• Largest Size

Silt

• Smooth when dry, non-sticky when wet

• smaller than sand particles

Clay

• Smooth when dry, sticky and slippery when wet

• Smallest

Loam

• a mixture of sand, silt and clay in equal amounts

• smooth and gritty texture

Different soil can hold different amounts of water

• the small particles of clayey soil are closely packed, so it can hold a lot of water

• the larger particles of sandy soil are loosely packed, so it can hold vey little water

• In loamy soil, the particles are neither too big or too small, So they hold just the right amount of water. This is why this soil is best for growth of plants
