The wind helps plants grow

AGRICULTURE - U.S. researchers have shown that corn and soybeans grow best at the foot of wind ...

One more argument against the opponents of wind turbines. Researchers U.S. the U.S. Department of Energy studied crops around the turbines located in the Midwest. According their first results, the wind generated by wind turbines would help plants stay cool and dry, and even help fight against fungi and to better capture the CO2 required for growth.

Beneficial especially in spring and fall

By measuring the temperature of the plants, the researchers found that those who benefit from increased wind experienced by smaller variations heat. The warm days and cool nights would be detrimental to plants and less by accelerating the exchange of air between the plants and the atmosphere. "We believe that the effects of wind turbines will be particularly beneficial in the spring and fall to conserve heat and prevent frost," said Gene Tackle, agronomist Ames Laboratory , who led the research.
Another positive effect of the wind turbines would be their effect on moisture. The wind would dry more quickly and limit the dew and the proliferation of fungi and harmful toxins. Finally, researchers believe that wind turbines could improve the natural absorption of CO2 by plants and allow them to grow faster.

conditioning natural

The wind would play a role in natural air conditioners: "The effects of wind turbines are certainly subtle but in some years, and in some circumstances they could be significant, said Gene Tackle. When you have been with a series of days at 40 ° C, wind from additional wind turbines could be useful. If they can bring down the temperature below 37 ° C, it would be a helpful to plants.
