Phosphorus losses from turfgrass areas are perceived to contribute to water quality problems, yet a comprehensive review of P fate in turfgrass ecosystems is lacking. According to available data in the literature, phosphorus fertilizer inputs (2–10 kg ha–1) slightly exceed the estimated outputs of phosphorus in clippings (0.4–7.5 kg ha–1). Sediment losses from turf areas are negligible, general...

Phosphorus (P) added to soil from fertilizer or manure application could pose a threat to water quality due to its role in eutrophication of fresh water resources. Incorporating such amendments into the soil is an established best management practice (BMP) for reducing soluble P losses in runoff water, but could also lead to higher erosion. The objective of this study was to test whether incorp...

To raise the eco-efficiency of the economy, it is important to not only investigate the eco-efficiency of specific products but also to ascertain whether the resources are used effectively throughout the life cycle. In this paper, we address eco-efficiency of agricultural use of phosphorus in Japan in the years 2005, 2010, and 2011. The increase in revenue from crops due to the use of phosphoru...

The recent resurgence of hypoxia and harmful algal blooms in Lake Erie, driven substantially by phosphorus loads from agriculture, have led the United States and Canada to begin developing plans to meet new phosphorus load targets. To provide insight into which agricultural management options could help reach these targets, we tested alternative agricultural-land-use and land-management scenari...
