Description
Phosphogypsum, a byproduct of phosphoric acid production, is 85-93% gypsum and is a potential source of sulphur and calcium for crops. Phosphogypsum is presently accumulating at the rate of more than I SO million tonnes annually world wide. A field study was conducted for 2 years to evaluate the influence of phosphogypsum on bahiagrass (Paspalum notatum Flugge) production in Florida. Treatments consisted of 5 rates of phosphogypsum (0, 0.2, 0.4 and 1.0 Mg phosphogypsum/ha applied annually and 2.0 and 4.0 Mg phosphogypsum ha applied at a one time application). Treatments were replicated 4 times in a randomised complete block design. Both bahiagrass yields and quality were increased by the addition of phosphogypsum. Thus this study shows that phosphogypsum may be a viable source of S and Ca for bahiagrass production.
