| Action | Effect | Result (W.R.T. fertility) |
| Construction of embankments. | Protects soil from being washed away. | Protects fertility of soil. |
| Planting trees. | Wind speed decreased. | Protects fertility of soil |
| 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. | Humus content increased. | Increases the fertility of soil. |
| Trenches are dug across a slope. | Check the velocity of water running along the slopes. | Protects fertility of soil |
| Litter is burnt in the farm. | Decreases the amount of organic material in soil. | Decreases the fertility of soil. |
| Decomposed vegetal litters, roots of plants and remains of animals. | Proves favourable for micro organism. | Increases the fertility of soil. |
| Excessive Irrigation | Salt content in the soil increases. | Decreases the fertility of soil |
| Chemical fertilizers used excessively. | Leads to the lowering of humus content in the soil. | Decreases the fertility of soil |
