Good points Skipster. Exact doesn't need the phosphorus--maybe K is adequate, also. Remember K has nothing to do with green color. What does your typical soil test indicate in your area?

Polymer-coated urea does not depend on bacteria for nitrogen release. It should release fine in cool weather. And besides, when you read the fine print--the mixture only contains 3 percent slow release nitrogen. Or 1.5 pounds in the bag.
When you read the bottom line it looks like they claim 15 percent slow-release.
They are basing their claim on the idea that 15 percent of the nitrogen is slow release. 3.1 over 21 is 14.67 percent of nitrogen as slow-release. This is a bit misleading unless you read and compare labels carefully.
