1. Sprinkler system

2. Drip system

Q-7. If wheat is sown in the kharif season, what would happen? Discuss.

Q-8. Explain how soil gets affected by the continuous plantation of crops in a field.

Ans: Soil can lose mineral nutrients to the plant which are essential for their growth. Continuous plantation of crops make the soil poor in nutrients, this makes the soil infertile.
