I am orange in colour and mostly found in the coastal belt of Konkan.
I am black in colour and have less organic components.

| Construction of embankments. | ||
| Wind speed decreased. | ||
| Farm land is kept fallow for some period. | Helps to maintain the pH balance and increase the proportion of humus. | Increases the fertility of soil. |
| Regular use of organic manures, vermicompost and compost. | ||
| Check the velocity of water running along the slopes. | ||
| Litter is burnt in the farm. | ||
| Decomposed vegetal litters, roots of plants and remains of animals. | ||
| Salt content in the soil increases. | ||
| Leads to the lowering of humus content in the soil. |
