Managing legacy and new sources of phosphorus to reduce leaching in Mid‐Atlantic soils

Application of phosphorus (P) fertilizers and animal manures to P‐rich soils due to the historic use of P inputs can lead to greater P losses. In these soils, we need to manage legacy and new inputs of P in a way that they do not lead to P loss. Studies were conducted to (i) determine the effect of soil type on P leaching and (ii) investigate if changes in dairy and poultry diets can lead to lower P in manures and loss when manures are land applied.
