This month the greens are recieving an application of gypsum. One downside to using recycled water is it has high levels of sodium, which over time, builds up in the soil profile after each watering cycle and deteriorates the soil structure causing slow water infiltration, impaired oxygen movement and a reduction in nutrient availability to the turf. Calcium, gypsum's main component, solubilises after application and exchanges with sodium ions on soil surfaces which allows the sodium to be removed from the soil profile by irrigation water.
