Document Summary

Organic production: defined in federal law and regulated through and extensive certification process, from field to fork, orga(cid:374)i(cid:272) produ(cid:272)tio(cid:374): a produ(cid:272)tio(cid:374) s(cid:455)ste(cid:373) that is (cid:373)a(cid:374)aged . Nutrition: mothers consuming mostly organic milk and meat products were found to have about. Long terms usda-ars research has shown that organic farming practices significantly build soil organic matter content: use of manure and cover crop more than offset losses from tillage. Isu research shows that 4th year organic rotation crops rose above convetional averages: attributed to soil quality improvements, most organic matter, enhances microbial activity, reduced soil acidity. Biodiversity: fundamental to organic farming, diverse plant communities supports beneficial insect communities that manage pest populations, eliminating the need for highly toxic pesticides, organic farming increases biodiversity at every level of the food chain, bacteria to mammals. No genetic engineering: gmos are not allowed in organic production, bt corn harms aquatic insects and disrupts stream ecosystems.
