Question

farmers are advised to grow wheat and legume crops alternatively. Why?​

Answer 1

Answer:

FARMERS ARE ADVISED TO GROW WHEAT AND LEGUME CROPS ALTERNATIVELY TO MAINTAIN THE FERTILITY OF THE SOIL. THE ROOT NODULES OF LEGUMINOUS PLANTS ARE HOME TO RHIZOBIUM BACTERIA'S WHICH TRAP THE NITROGEN FROM AIR AND CONVERTS TO SOLUBLE NITRATES AND NITRIDES WHICH INCREASES THE FERTILITY OF THE SOIL.
