Sulfur coated urea is subject to some pretty rough handling before they hit the ground and reaches your turf - in loading, shipping, blending and bagging. Granule coating breakdown. This yields highly uniform urea granules and pays off in better sizing and finished blends. After the sulfur coating is applied, we add a proprietary sealant to provide the durability needed to provide consistent performance on the turf. Nitrogen sulfur coated urea coating actually works.
Tests Prove It .
The fertilizer industry uses a standard, seven-day test to measure nitrogen plant food release rates. First, a 50-gram product sample is placed in 250 milliliters of water at 100 degrees F for seven days. Then the percentage of nitrogen released from the sample during the test period is measured. The industry uses a second test to simulate the effects of shipping, blending and other handling. Coated nitrogen is dropped 35 feet down a pipe onto a steel plate.
