Crops often receive beneficial nutrients such as phosphorus (P) from manure or commercial fertilizer applications. However, the Delaware Nutrient Management Law (3 Del. C. § 2247) limits the amount of ...

Phosphorus is essential for agriculture, yet this important plant nutrient is increasingly being lost from soils around the world. The primary cause is soil erosion. The study shows which continents ...

Permafrost thaw can stimulate the release of soil carbon, triggering a positive carbon-climate feedback that may be mediated by changes in soil phosphorus (P) availability. A research team led by Prof ...

A Penn State-led study analyzed data from 430 rivers across the U.S. and found that phosphorus loss from agricultural lands has increased over the past four decades, despite efforts to reduce it. This ...
