Food, Soil, and Pest Management Core Case Study: Organic Agriculture Is on the RiseOrganic agriculture
Crops grown without using synthetic pesticides, synthetic inorganic fertilizers, or genetically engineered seeds
Animals grown without using antibiotics or synthetic hormones
U.S. in 2008: .6% cropland; 3.5% food sales
Europe, Australia and New Zealand much higher
Industrialized Agriculture vs. Organic AgricultureFig. 12-1, p. 277 Fig. 12-1a, p. 277Industrialized AgricultureUses synthetic inorganic fertilizers and sewage sludge to supply plant nutrientsMakes use of synthetic chemical pesticidesUses conventional and genetically modified seedsDepends on nonrenewable fossil fuels (mostly oil and natural gas)Produces significant air and water pollution and greenhouse gasesIs globally export-orientedUses antibiotics and growth hormones to produce meat and meat products Fig. 12-1b, p. 277Organic AgricultureEmphasizes prevention of soil erosion and the use of organic fertilizers such as animal manure and compost, but no sewage sludge to help replace lost plant nutrientsEmploys crop rotation and biological pest controlUses no genetically modified seedsReduces fossil fuel use and increases use of renewable energy such as solar and wind power for generating electricityProduces less air and water pollution and greenhouse gasesIs regionally and locally orientedUses no antibiotics or growth hormones to produce meat and meat products ...
