Main Body
Diagram showing zonation of soils across India: Piedmont soil, Alluvial soil, Sandy soil, Black soil, Laterite soil, Red soil. Temperature: High temperature leads to good nutrient rate of extraction
Continuation: Temperature factors: red soils in high insolation area; black soil owing to ground temperature (basalt-deccan trap); leaching in tropical soils. Rain factors: coastal soils due to sand & saline intrusion; rain leads to sheet erosion on mountains; lack of fertility in evergreen forests due to continuous rains
