Conventional farming, by its very nature, has an adverse effect on microbial properties of soil. Conventional farming degrades soil fertility, increases erosion, and cause more resistant pests. They also cause massive amounts of pollution from runoff and chemicals used (pesticides, herbicides, antibiotics, hormones, and waste residues. read more
