Question

i) Why does the field need to be ploughed and watered before sowing? (1) 1) Why is manure better than chemical fertilizers to provide nutrients to the

crops? (1)

Answer 1

Answer:

1) Plowing makes soil porous which helps the water to penetrate deeper and retain moisture for longer times. This process helps to germinate easily and spread roots deep. It helps the plant to absorb the required nutrients and moisture from the deeper parts of the soil.

2) Manure is better than fertiliser. Manure is derived naturally and adds a lot more than just nutrients to the soil. They increase the activity of the microbes in the soil and increase its fertility.
