Study Shows No-Till's Benefits for Pacific Northwest Wheat Growers
March 11, 2011| |
Studies at the Agriculture Research Service - Columbia Plateau Conservation Research Center in Pendleton, Oregon have shown that no-till management can reduce soil erosion across entire production fields. ARS researchers led by John Williams compared water run-off, soil erosion and crops yields in a conventional intensively tilled winter wheat fallow system and a no-till 4-year cropping rotation system.
Research conducted in 2001 to 2004 measured runoff sediment and loads at the mouth of each drainage channel in the study after almost every rainfall. Results showed that no-till production, saved the soil surface and protected pore space beneath the soil surface, thus allowing more water to infiltrate into the subsoil. In addition, direct seeding in no-till production saved fuel and time.
The No-till technology is an important feature of the use of herbicide resistant genetically modified crops.
