Agronomic Performance of Cropping Systems with Contrasting Crop Rotations and External Inputs
AGRONOMY JOURNAL, pp. 182-192, 2011.
Cropping systems with less reliance on external inputs could improve agricultural sustainability if they can produce high and stable crop yields over time. A 16-yr experiment was conducted in southwestern Minnesota to evaluate the effects of zero external input (ZEI), low external input (LEI), high external input (HEI), and organic input ...More
