Soil Geography

Soil geography is a branch of soil science study about the patterns of soil, distribution of the soil on the earth. Soil is made up of rock particles Each component and their size, play an important role. The large particles, sand, determine aeration and drainage characteristics and the tiniest, sub-microscopic clay particles, are chemically active, binding with water and plant nutrients. The ratio of these sizes determines soil type: clay, loam, clay-loam, silt-loam.
