Importance of soil physical properties Sports Field

Soil texture is based on the relative proportion of sand, silt and clay the soil contains and is used to name the soil, for example a sandy loam soil. Coarse-textured soils (sands, loamy sands, sandy loams) have a large particle size and do not have great water and nutrient holding capacity.

SOIL THEIR TYPES AND PROPERTIES Blogger

Jul 17, 2017So, sandy soils tend to be light, well aerated and rather dry. 2. Clayey soil If the proportion of fine particles is relatively higher, then it is called clayey soil. Clay particles, being much smaller, pack tightly together, leaving little space for air. Unlike sandy soil, water can be held in the tiny gaps between the particles of clay. So clay soils have little air.

Sandy soils are made up primarily of sand particles, which are larger than the particles that are predominant in clay or silt soils. Because water drains away quickly from the relatively large spaces between the sand particles, sandy soils dry out quickly, and they also don't retain soil nutrients as effectively as denser clay and silt soils.

What Are the Characteristics of Red Sandy Soil

Sandy soils are often acidic and have fewer nutrients than clay, loam or peat soils. The higher proportion of sand makes sandy soil grittier than other types. When a handful of red sandy soil is squeezed into a lump, the lump easily falls apart. This is in direct contrast to clay-based soils, which hold their shape when compressed.
