Shifting crop-pasture rotations to no-till annual cropping reduces soil quality and wheat yield

When crop-pasture rotations are converted to continuous no-till annual cropping systems, the grain yield of wheat crops in the rotation stagnates or declines in response to the number of years of continuous cropping (YCC). We studied the soil properties underlining the response of wheat yield to YCC in 80 on-farm trials during three growing seasons. We determined the frontier yield and the yield gap under limited (YF−, or best technical means)...
