Fall‐applied manure can conserve excess soil‐profile inorganic‐N for the subsequent cropping year
Journal of Environmental Quality, EarlyView.Abstract To investigate dairy manure urea fertilizer interactions in cropped soils of the semiarid‐West, we fall‐applied and incorporated (0–0.3 m) soil urea‐N (FertN) rates of 10 (N0), 45 (N1), and 80 mg N kg−1 (N2), co‐applied with either no manure or 86 Mg ha−1 (dry wt.) stockpiled dairy manure.
