.A British meta-analysis published in 2012 identified some of the stresses that were higher in organic agriculture. For example, it found that ammonia emissions, nitrogen leaching, and nitrous oxide emissions per product unit were higher from organic systems, as were land use, eutrophication potential, and acidification potential per product unit.
Lower crop yields in organic farming are largely inevitable, owing to the arbitrary rejection of various advanced methods and technologies. Organic practices afford limited pesticide options, create difficulties in meeting peak fertilizer demand, and rule out access to genetically engineered varieties. If organic production were scaled up significantly, the lower yields would lead to greater pressure to convert land to agricultural use and produce more animals for manure, to say nothing of the tighter squeeze on water supplies all of which are challenges to sustainability
