The part of the earth's surface consisting of humus and disintegrated rock; SYN. dirt.
Loose covering of broken rocky material and decaying organic matter overlying the bedrock of the Earth’s surface. Various types of soil develop under different conditions: deep soils form in warm wet climates and in valleys; shallow soils form in cool dry areas and on slopes. Pedology, the study of soil, is significant because of the relative importance of different soil types to agriculture.
The organic content of soil is widely variable, ranging from zero in some desert soils to almost 100% in peats.
