Question

why are nitrogenous fertilizers not added in the soil in which leguminious plants are grown​

Answer 1

Answer:

The roots of leguminous plants contain nitrogen fixing bacteria such as rhizobium. Rhizobium converts atmospheric nitrogen into nitrates and nitrites by the process of nitrogen fixation and releases it into the soil. The nitrates and nitrites released into the soil are absorbed by the roots of the plants and utilised for various purposes. Hence, nitrogenous fertilizers are not added in the soil in which leguminous plants are grown.
