Phosphorus (P) loss from agricultural fields and watersheds has been an important water
quality issue for decades because of the critical role P plays in eutrophication. Historically …

Agricultural intensification has led to a large increase in drained arable land and pastures
worldwide over the last two centuries. The installation of land drains not only affects the …

Most phosphorus (P) modeling studies of water quality have focused on surface runoff loses.
However, a growing number of experimental studies have shown that P losses can occur in …

The prevalence of anthropogenic drainage systems in intensively cropped areas across
North America combined with the degradation of important freshwater resources in these …

Imbalanced nutrient management has caused soil phosphorus (P) to become an
environmental rather an agronomic problem in more economically developed countries …

Phosphogypsum (PG) is a waste produced by the phosphate fertilizer industry that has
relatively high concentrations of some heavy metals (eg, Cd, Cr, Cu, Pb, V, and Zn). The …

Phosphogypsum (PG), a by-product of the phosphate fertiliser industries, has been applied
as soil amendment to reduce Na saturation in soils, as in the reclaimed marsh area from SW …

The objective of this study was to investigate the effects of phosphogypsum (PG)
amendment on the physiochemical proprieties of saline and agricultural soils along with the …

Marisma, one of the largest salt-marsh alluvial areas in SW Spain, has been reclaimed since
1970 by artificial drainage and amendment with phosphogypsum (PG) so as to reduce Na+ …

Phosphogypsum (PG) has been usually applied as Ca-amendment to reclaim sodic soils
such as those in the marshland area of Lebrija (SW Spain). This work aimed at the effects of …
