| Litter is burnt on the farm. | The proportion of ash in the soil gets increased. | Decrease in Fertility |
| Use of organic manures | Proves favorable for micro-organisms | Increase in Fertility |
| Excessive irrigation | The salt content in the soil increases | Decrease in Fertility |
| Chemical fertilizers used excessively | Decrease the number of microorganisms and so the proportion of humus in the soil | Decrease in Fertility |
