Question

why farmers grow leguminous plant in their farms​

Answer 1

Answer:

Leguminous plants have nitrogen fixing bacteria at their root nodules. these bacteria take up atmospheric nitrogen and convert them to nitrous compounds which are useful to plants thus increasing the fertility of the soil. this helps in the growth of other plants grown with the leguminous plants .

Explanation:

Modern agriculture generously makes use of synthetic fertilizers,which nourishes the plants but may cause land degradation. Most widely used synthetic fertilizers are nitrogen fertilizers. Leguminous plants can harbor atmospheric nitrogen fixing bacteria in their roots, setting the stage for a symbiotic relationship. In this relationship, plants provide food to bacteria and in turn bacteria provide nitrogen compounds to the plants, synthesized by fixing atmospheric nitrogen. Some of the fixed nitrogen so may be also left in the soil benefiting the subsequent crop.

Also leguminous plants have relatively deeper root system which helps in opening up the sub-soil and recycling of nutrients moved into deeper layers, again benefiting the subsequent crop.

Thus it is always advisable to include leguminous crops in all cropping patterns.
