Water quality impairment is a growing issue in the United States and many other countries. It is no surprise that humans play a large part in the creation of that problem. In the United States alone, more than 100,000 miles of rivers, close to 2.5 million acres of lakes, reservoirs and ponds, and more than 800 square miles of bays and estuaries are classified as having poor water quality due to excess sediment or nutrient levels. Human impacts on poor water quality come from a number of sources, with agricultural practices being one of the leading culprits for many water bodies.
The use of gypsum may be a viable option to help reduce overall losses of P to surface water. A number of studies have looked at gypsum in this context with a number of differing outcomes observed. A dive into published literature to help better understand possible outcomes associated with gypsum's use is completed here.
