3. Vertisols :
Dark or black swelling clays, deep cracks develop when dry
4. Oxisols :
Oxide, sesquioxide rich soil, highly weathered soils of tropical regions
5. Alfisols :
Relatively young soils, acid soils, larger in forest soils
6. Histosols :
Called organie soil, have more than 20% O.M.
@agriexam123
7. Aridisols :
Desert soils of arid regions.
8. Spodosols:
Such soils are with sub soil accumulation of sesquioxide and humus
9. Ultisols :
Low nutrient, low base status, forest soils. Oldest soil.
10. Mollisols :
Soft, grass land dark soils of steppes and prairies, high base status

Especially destruction of cellular protoplast of mid gut epitheiium
e.g. heavy metals, such as Cu, Hg, fatty acids.
