Evaluating optimum seeding distances from subsurface banding poultry litter in crop rotations

Poultry litter is a nutrient-dense fertilizer, but surface applications lead to nutrient losses air, soil, and water. Objectives were evaluate optimum subsurface-applied poultry bands from crop seeding distance in corn (Zea Mays L.)–soybean [Glycine max (L.) Merr.] rotation. Soil amendment treatments included planting 13, 25, 38 cm subsurface-banded litter, surface-applied inorganic nitrogen (N), 0 kg N ha−1 (control) Year 1, followed by soybean 2 (no new soil applications). Across subsurface treatments, grain silage yields 45 30% greater compared with applications, respectively, not differing 25- 38-cm during harvest. In 2, 26% than N. Consequently, banding may be an ecologically agronomicallyviable replacement for systems corn–soybean rotations.
