Soil Texture and Structure - carlisle.k12.ky.us

The texture of a soil is important because it determines soil characteristics that affect plant growth. A few of these characteristics are water-holding capacity, permeability, and soil workability. Water-holding capacity is the ability of a soil to retain water. Most plants require a steady supply of water, and it is obtained from the soil.
