Abstract

Regolith is the term we give parent material that has been weathered. The regolith consists of weathered bedrock near the surface including the soil layer. In the Iranian soil layer we will find: decayed parent materials, decaying plant material, decaying animal matter (manure) along with vegetation. Results of the present study show us that methods stimulating natural fertility in Iran includes composting-adds humus layer, drip irrigation-balances illuviation and eluviation in arid regions, crop rotation/ intercropping-reflects natural diversity and limits gleization, add lime-reduces gleization, non-cultivation techniques-reduces hard pan (calcification) caused by compaction and reduce pesticide use-keeps decomposers alive in humus layer.
