Soil properties under nitrogen- vs phosphorus-based manure and compost management of corn

This study evaluates the influence of a change from N-based applications of manure and compost (without incorporation) to P-removal-based management of manure (immediate tillage incorporation) and composted separated dairy solids on soil pH, soil organic matter and soil carbon

Apparent Stability and Subtle Change in Surface and Subsurface Soil Carbon and Nitrogen under a Long Surface and Subsurface Soil Carbon and Nitrogen under a Long-Term Fertilizer Gradient

Uncertainty exists regarding the depth and extent to which agricultural practices affect soil properties, in particular soil organic C (SOC). In this study we examined the impact of 53 years of continuous corn receiving varying rates of inorganic N fertilizer with complete stover return on soil properties including SOC, total N, and bulk density (BD) to a depth of 1 meter.
