Phosphorus lability across diverse agricultural contexts with legacy sources
Journal of Environmental Quality, EarlyView.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

Remote Sensing in Ecology and Conservation, Volume 8, Issue 6, Page 841-854, December 2022., 2022 The African savannah ecosystem is populated by nomadic pastoralists who corral livestock at night in temporary enclosures, called bomas, to protect them. The number and distribution of bomas in the savannah is important from an ecological perspective. However, no studies have yet examined the spatial‐temporal dynamics of bomas and their relationship to

Evaluation of Minnesota Phosphorus Loss Index performance
Journal of Environmental Quality, EarlyView.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.

Toward a transdisciplinary and unifying definition of legacy phosphorus
Journal of Environmental Quality, EarlyView.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.

Changes in Manure Management in the Hog Sector [PDF]
In recent years, structural changes in the hog sector, including increasing farm size and regional shifts in production, have altered manure management practices. Over the same period, changes to the Clean Water Act, new state regulations, and increasing

Journal of Environmental Quality, EarlyView.Abstract The Eastern Corn Belt (ECB) node of the Long‐Term Agroecosystem Research (LTAR) network is representative of row crop agricultural production systems in the poorly drained, humid regions of the US Midwest and a significant focus for addressing water quantity and quality concerns affecting Lake Erie and the Gulf of Mexico.
