Maizorb Field-Dry is an athletic field drying compound that is 100% organic, non-toxic, and biodegradable; the manufacturer says one bag of this product equals four bags of clay products. To use you remove standing water, cover wet areas with ¼-inch of the product, let stand for a few minutes, then level and rake into the soil. Product is nearly 60 years old but not previously marketed to sports turf professionals.
