A mixture of weathered rock, rock fragments, decayed organic matter, water, and air.
weathering
soil
decomposition
horizon
Soil composed of sand, silt, and a small amount of clay; best for most garden plants because it holds plenty of moisture but also drains well so that sufficient air can reach the roots
