Fertilizers – Quick-Release and Slow-Release Nitrogen – What’s the difference?
Fertilizers are applied to turfgrass lawns to provide supplemental nutrients that will help produce a reasonable amount of top growth, but not at the expense of root growth or carbohydrate storage. A good root system is the key factor to a healthy lawn.
The three main supplemental nutrients that compose a complete fertilizer are nitrogen (N), phosphorus (P), and potassium (K). There are two basic types of nitrogen sources contained in lawn fertilizers – slow-release and quick-release - and it’s important to know the pros and cons of both.
