Soil properties include texture and color. Soil contains minerals which in turn, determine its texture. Sand contains the largest particles, silt is finer and clay is the finest of particles in terms of size. Ideally, soil that is called a loam contains 40 percent sand, 40 percent silt and 20 percent weight. This is a good soil for growing crops and retaining moisture for the plants. A sandy soil contains rock fragments with particles ranging from 2.0mm to .05 mm. Silt particles are .05mm to .002 mm in size. Clay particles are .002mm or less. The color of soil is due to the minerals it contains. Therefore, if it is high in iron, it may appear yellow or reddish. Soil containing high organic matter known as humus, usually looks black or brown. Maganese, sulfur and nitrogen form black mineral deposits. Aerobic environments produce gradual color changes while anaerobic can result in rapid color flow with mixed up patterns, in a soil profile.
