Soil chemistry and nutrient concentrations in perennial ryegrass as influenced by gypsum and carbon amendments

Plant growth is affected by soil properties that can be improved through addition of amendments and other management practices. Use of gypsum as a soil amendment for improving agricultural yields, and soil and water quality is increasing, but knowledge is lacking on how it affects the soil&#8217...
