Answer:
In general, soil contains 40-45% inorganic matter, 5% organic matter, 25% water, and 25% air. ... The inorganic material of soil is composed of rock, which is broken down into small particles of sand (0.1 to 2 mm), silt (0.002 to 0.1 mm), and clay (less than 0.002 mm). Loam is a soil that is a mix sand, silt, and humus.
Loam soil is composed of almost equal amounts of sand and silt with a little less clay. A good ratio is 40 percent each of sand and silt, and 20 percent of clay. Generally speaking, loam describes the ideal soil composition for most garden plants. (Some plants like sandy or rocky soil, and some even like clay.)
