Delineation of management zones in integrated crop–livestock systems

Agronomy Journal, 2021
AbstractThe lack of studies on spatial variability in integrated crop–livestock systems (ICLS) hinders understanding how to increase their efficiency by implementing precision agriculture (PA) practices. As such, little is known about how grain and forage crops interact and how to improve the decision‐making process on fertilization and forage ...
