(36,286 posts)"After an initial decline in yields during the first few years of transition, the organic system soon rebounded to match or surpass the conventional system. "

Organic corn yields were 31% higher than conventional in years of drought. These drought yields are remarkable when compared to genetically engineered drought tolerant varieties which saw increases of only 6.7% to 13.3% over conventional (non-drought resistant) varieties.
Corn and soybean crops in the organic systems tolerated much higher levels of weed competition than their conventional counterparts, while producing equivalent yields. This is especially significant given the rise of herbicide-resistant weeds in conventional systems, and speaks to the increased health and productivity of the organic soil (supporting both weeds and crop yields).
