Answer 1

Answer:

Explanation: 1. It depends upon the soil fertility, how much humus it contains and the amount of vegetation growing over there.

2. Rhizobium bacteria is present in the root nodules of leguminous plants and helps in nitrogen fixation.

3. Plants can't take up atmospheric nitrogen directly, so rhizobium bacteria is present in the root nodules of leguminous plants because it can take up the atmospheric nitrogen and then convert it into soluble forms which the plants can take up.
