Question

why is nitrogen fertiliser not added to soil in which leguminus plants are grown?​

Answer 1

Nitrogenous fertiliser is not added in soil in which leguminous plants are grown because the nitrogen fixing bacteria reside in the root nodules of the leguminous plants. These bacteria convert atmospheric nitrogen into soluble nitrogenous compounds. Hence the soil in which legumes are grown becomes rich in nitrogen and does not require nitrogenous fertilsers.

Answer 2

$\huge{Hi}$
