Phosphorus lability across diverse agricultural contexts with legacy sources
Abstract The buffering of phosphorus (P) in the landscape delays management outcomes for water quality. If stored in labile form (readily exchangeable and bioavailable), P may readily pollute waters. We studied labile P and its intensity for >600 soils and sediments across seven study locations in the United States. Stocks of labile P were large enough

Evaluation of Minnesota Phosphorus Loss Index performance
Abstract Supported by the National Phosphorus (P) Research Project led by Dr. Andrew Sharpley, Minnesota developed its statewide P‐Index, the Minnesota P Loss Index (MNPI), to manage critical source areas of agricultural P. The MNPI has remained unchanged since its last revision in 2006.

The importance of periodic droughts for maintaining diversity in the freshwater environment [PDF]
Whereas some species may rely on periodic drought conditions for part of their life histories, or have life strategies suited to exploiting the habitat or changed environmental conditions that are created by drought, for other organisms it is a time of ...

Toward a transdisciplinary and unifying definition of legacy phosphorus
Abstract Legacy phosphorus (P) is a concept advanced by Dr. Andrew Sharpley and colleagues that was originally applied to the persistence of anthropogenic signatures in watersheds, and it has since been adopted in a diversity of settings to help guide the science and management of P.

Connecting the soil health–water quality nexus under surface‐irrigated conservation tillage
Abstract Intense tillage degrades soil health, worsens soil structure, and accelerates nutrient and sediment transport to vulnerable water bodies. Unfortunately, few studies have measured both soil health and water quality under conservation tillage, particularly in semi‐arid furrow‐irrigated fields, limiting our understanding of tillage impacts in ...
