Can we increase water retention on sandy soil and in effect reduce water used in irrigation?
Water retention or savings is difficult to accurately measure because of the lack of creditable record keeping. Prestancia Country Club in Sarasota, Florida uses reclaimed water from the Waste Water Department of the city of Sarasota and is metered to the golf course solely for the purpose of irrigation. They have been using the product since June of 1992 and they have established a usage rate on their irrigation system of that has saved them over 50% in water usage over their previous eight years of operation. This does take into account the rain-fall which is factored into their irrigation program. Over 70% 0f this course is sandy.
