Question

Why leguminous crop rotation employed in agriculture?

Answer 1

Leguminous crop rotation and other crop rotations are employed in agriculture since in such type of plants many bacteria significant for the nitrogen cycle live. The leguminous crop rotation (or conjointly with main crop) aids the soil to become rich in nitrates which then are absorbed by plants. Green manure, the covering of soil with grass and leguminous, is a manner to perk up the fixation of nitrogen and it is an option to evade chemical fertilizers.
