Answer:
- by planting more and more trees
- by doing drip irrigation
- by doing crop rotation
Explanation:
- roots of plants prevents the fertility of plants as when heavy rain or heavy winds blow then it protects the humus of the soil not to blown up with water or wind
- if we do drip irrigation in place of heavy irrigation then it protects the humus as well as the water as with water the top layer i.e. humus sheds off with the water
- by doing crop rotation we can protect the fertility of the humus as this rotation helps the land not to degrade because when we practice this then the bacteria present in leguminous plants to regain it's fertility
