FOOD PRODUCTION ENERGY EXPENSIVE. IV. "While agricultural output increased as a result of the Green Revolution, the energy input to produce a crop has increased faster, so that the ratio of crops produced to energy input has decreased over time. Green Revolution techniques also heavily rely on chemical fertilizers, pesticides and herbicides and rely on machines, which as of 2014 rely on or are derived from crude oil, making agriculture increasingly reliant on crude oil extraction.""

GREENREV FED THE WORLD. III. "Cereal production more than doubled in developing nations between the years 1961–1985. Yields of rice, maize, and wheat increased steadily during that period. The production increases can be attributed roughly equally to irrigation, fertilizer, and seed development, at least in the case of Asian rice."" " http://lnkd.in/dmXPY8k View in LinkedIn

MOLBIOL HELPED GREENREV. II. "With advances in molecular genetics, the mutant genes responsible for Arabidopsis thaliana genes were cloned. Stem growth in the mutant background is significantly reduced leading to the dwarf phenotype. Photosynthetic investment in the stem is reduced dramatically as the shorter plants are inherently more stable mechanically. Assimilates become redirected to grain production, amplifying in particular the effect of chemical fertilizers on commercial yield." http://lnkd.in/dmXPY8k View in LinkedIn

FOSSIL FUEL FERTILIZERS ARE EXPENSIVE. "From the standpoint of industrial efficiency, it's too bad we can't simply drink petroleum directly, because there's a lot less energy in a bushel of corn (measured in calories) than there is in the half-gallon of oil required to produce it. Ecologically, this is a fabulously expensive way to produce food—but "ecologically" is no longer the operative standard. In the factory, time is money, and yield is everything.""

SUBSIDIZED FERTILIZERS. "Fertiliser intended for government subsidy programmes is sometimes diverted and sold to farmers at or near market prices. Failure to account for such ‘leakage’ can upwardly bias econometric estimates of the effect of government fertiliser subsidy programmes on total fertilizer use.""

LACK OF CROP ROTATION HURTS SOIL. Case study. "Soy takes more out of the soil than farmers can afford to put back by way of fertilizers. Only 37 percent is restored, meaning that 63 percent of each season's loss remains lost, according to government data.""

CROP ROTATION DROPED AFTER WWII. "Today, Midwest farms often rotate between just corn and soybeans. But decades ago, oats, clover and alfalfa were a big part of the mix—and more farms also had livestock. The combination allowed for replenishment of nitrogen in the soil, both through the spreading of manure and by varying what types of crops went into the land. But after World War II, nitrogen fertilizer became widely available, and that made rotations and livestock less necessary." http://lnkd.in/dzg56Bq View in LinkedIn

INDUSTRIAL AGRICULTURE (IV). "The transition from local to industrial mostly took place during the fifty-year span of the last half of the last century... an oppositional food movement emerged almost as soon as the industrial food movement began. Today, the fastest growing segment of the food market in not fast foods, convenience foods, or inexpensive industrial foods but instead is “natural foods.” The local foods movement is but the latest phase of the natural foods movement." http://lnkd.in/d3dHPvX View in LinkedIn
