Organic farming utilizes techniques like crop rotation and organic manures to nourish soil fertility. Crop rotation, the recurrent succession of crops on the same land, improves soil structure and nutrients while suppressing weeds and pests. Organic manures, including bulky manures like farm yard manure and compost, as well as concentrated manures from oilcakes, are also used to increase soil nutrients. Vermicompost and other composts are additionally employed in organic agricultural practices.
