Organic food is better?
Comments (150)Another quote "Enough Nitrogen To Go Around? In addition to looking at raw yields, the University of Michigan scientists also examined the common concern that there aren't enough available sources of non-synthetic nitrogen-compost, manure, and plant residues-in the world to support large-scale organic farming. For instance, in his book Enriching the Earth: Fritz Haber, Carl Bosch, and the Transformation of World Food Production, Vaclav Smil argues that roughly two-thirds of the world's food harvest depends on the Haber-Bosch process, the technique developed in the early 20th century to synthesize ammonia fertilizer from fossil fuels. (Smil admits that he largely ignored the contribution of nitrogen-fixing crops and assumed that some of them, like soybeans, are net users of nitrogen, although he himself points out that on average half of all the fertilizer applied globally is wasted and not taken up by plants.) Most critics of organic farming as a means to feed the world focus on how much manure-and how much related pastureland and how many head of livestock-would be needed to fertilize the world's organic farms. "The issue of nitrogen is different in different regions," says Don Lotter, an agricultural consultant who has published widely on organic farming and nutrient requirements. "But lots more nitrogen comes in as green manure than animal manure." Looking at 77 studies from the temperate areas and tropics, the Michigan team found that greater use of nitrogen-fixing crops in the world's major agricultural regions could result in 58 million metric tons more nitrogen than the amount of synthetic nitrogen currently used every year. Research at the Rodale Institute in Pennsylvania showed that red clover used as a winter cover in an oat/wheat-corn-soy rotation, with no additional fertilizer inputs, achieved yields comparable to those in conventional control fields. Even in arid and semi-arid tropical regions like East Africa, where water availability is limited between periods of crop production, drought-resistant green manures such as pigeon peas or groundnuts could be used to fix nitrogen. In Washington state, organic wheat growers have matched their non-organic neighbor's wheat yields using the same field pea rotation for nitrogen. In Kenya, farmers using leguminous tree crops have doubled or tripled corn yields as well as suppressing certain stubborn weeds and generating additional animal fodder. The Michigan results imply that no additional land area is required to obtain enough biologically available nitrogen, even without including the potential for intercropping (several crops grown in the same field at the same time), rotation of livestock with annual crops, and inoculation of soil with Azobacter, Azospirillum, and other free-living nitrogen-fixing bacteria."...See MoreFood Fraud
Comments (14)I think it may go beyond things they listed. For the last 20 plus years I've been buying ground sirloin instead of ground chuck or round because of the little bits of grizzle that I was always getting in the chuck and round. But my last couple of packages of ground sirloin have turned up those same bits of grizzle. I'm beginning to think that I'll have to ask to see the ground sirloin ground in front of me. I know one of the local restuarants here was caught 'cutting' tenderloin filets out of regular steaks. Who do they think they're kidding? Anyone with a taste for these things is going to spot it. And it is a worry about the stuff from China. I don't want to buy anything from them. If there's anyone who has proved they're not to be trusted, it's China.
