Wind farms positively impact crops, study says

Image result for Wind Farms Positively Impact Crops, Study SaysIowa State University researchers have found that wind turbines located in agricultural fields are a plus for the crops growing around them. The overall effects on crops growing in wind farms appear to be positive said Gene Takle, Iowa State agronomy professor. Takle says wind blowing across a field without turbines creates a certain turbulence that carries moisture from the transpiring crop, which rises into the atmosphere and pulls down cooler, drier air. At night the wind is calmer and the land cools. Turbines take some of the wind energy, slowing it down but increasing its turbulence so it interacts with the crop more, possibly increasing evaporation from the crop or moving carbon dioxide down into the crop. “The biggest changes are at night …when it gets pretty calm, the crop cools down and if it’s a humid night you start to get dew formation. If you add the turbines, it looks a little more like the daytime. So the dew formation is delayed and it may start to evaporate sooner.” Since fungus and mold like a wet environment, the shorter the wet period makes it less favorable for the growth of those potential pathogens.
