Diversifying cropping systems enhances productivity, stability, and nitrogen use efficiency

Long‐term field experiments are useful for determining cropping system productivity, stability, and resource use efficiency. With 12 yr (2004–2015) of data from five cropping systems on a long‐term experiment (> 30 yr) under semiarid conditions in Saskatchewan, Canada, a systems‐approach was used to compare grain and protein yield, stability, nitrogen (N) dynamics, N fertilizer (FUE G,P ), and available N use efficiency (NUE G,P ) for grain...
