Question

how do leguminous plants help in maintaining soil fertility?​

Answer 1

Answer:

Explanation:

The plant supplies Rhizobium with sugars and Rhizobium gives the plant soluble nitrogen. Different crops are grown in the same field which helps prevent soil erosion and controls the spread of soil-borne plant disease. Leguminous plants will add nitrate to the soil which improves fertility.

Answer 2

Answer:

The leguminous plant increases the soil ripeness due to the Rhizobium bacteria in the root knobs of the plants. These microscopic bacteria changes over atmospheric nitrogen to a shape which can be utilized by plants. This reduces the nitrogen deficiency in the soil and makes it abundant.
