Small-Scale Wind Energy on the Farm
Iowa State University researchers have found that wind turbines located in agricultural fields appear to have positive overall effects for crops growing around them. Turbines increase wind turbulence in the field, possibly increasing evaporation from the crop or moving carbon dioxide down into the crop. Turbines also bring warmer air down toward the surface. Longer periods without dew help keep fungus and mold from forming amidst the crop. On the negative side, there is a tendency for higher temperatures to occur at night in wind farms, which can become a limiting factor for crop yields. On the whole, however, crops grown in wind farms seem to benefit.
