Laterite Soil:
-
Laterite soils are mostly the end products of weathering.
- They are formed under conditions of high temperature and heavy rainfall with alternate wet and dry periods.
- Heavy rainfall promotes leaching (nutrients gets washed away by water) of soil whereby lime and silica are leached away and a soil rich in oxides of iron and aluminium compounds is left behind.
- ‘Laterite’ means brick in Latin. They harden greatly on loosing moisture.
- Laterite soils are red in colour due to little clay and more gravel of red sand-stones.
- Laterite soils are rich in bauxite or ferric oxides.
- They are very poor in lime, magnesia, potash and nitrogen.
- Sometimes, the phosphate content may be high in the form of iron phosphate.
- In wetter places, there may be higher content of humus.
