ABSTRACT

Soils mean different things to different people. Soil scientists view soils as being made up of differently sized mineral particles (i.e., sand, silt, and clay) and organic matter. They have complex biological, chemical, physical, and mineralogical properties that are always changing with time. Agronomists, farmers, and gardeners, on the other hand, see soil as a medium for growing
