Answer 1

Answer:

Important crop plant such as wheat and corn do not have a useful relationship rhizobia. Instead, they rely on nitrates in the soil as a source of Nitrogen.

Due to continuous growing of same crops one after the other in the same fields, nutrients gets depleted and thus yields get low slowly.
