I t is said that lakes are born to die. As soon as a lake basin is formed, either slowly by
glacial action as for the Great Lakes or rapidly by the New Madrid earthquake for Reelfoot …

Low pH soils leached with gypsum solutions have been shown to sorb gypsum thereby
increasing calcium and improving root growth of some crops. However, in some situations …

Public concern regarding agriculture's contribution to surface water quality impairment has
increased in recent years. Specifically, phosphorus (P) has been identified as the most …

Soil health is an issue of global concern that influences, among other things, food security
and water quality. Certain farming practices, when properly applied, can protect and improve …

A series of bench scale studies was performed to determine the proper dosages of fly ash,
lime, and gypsum for removing soluble and total phosphtae from eutrophic lake water prior …

Phosphorus runoff from agricultural land to surface water bodies, such as the Great Lakes, is
an important environmental concern. Soil amendments, such as gypsum, may alter the …

The effectiveness of gypsum in reducing runoff P losses from soils and the mechanisms
responsible are well documented; however, gypsum amendment effects in reducing redox …

Agricultural systems are leaky and losses of phosphorus, nitrogen, organic matter and
suspended solids can impact on water quality. While direct contamination of surface water …

Abstract Phosphogypsum (CaSO4× 2H2O), later in the text referred to as gypsum, is a by-
product from the fertiliser industry. Studies of gypsum to improve soil structure and reduce …

Enrichment of surface waters with P can stimulate excessive growth of algae. When large
populations of algae die, they sink through the water and decay, thereby consuming large …
