How can you tell if a fertilizer is a "slow-release"? What are the best NPK ratios for this area?
Rate This FAQ
Slow-release fertilizers are typically more expensive than quick release formulations but provide an extended release of nitrogen over many weeks so you don’t have to apply them as often. Slow-release nitrogen available to homeowners is usually found in the form of sulfur coated urea (SCU) or can also be polymer-coated urea (PCU). The labels on the fertilizers are typically clearly marked with one of these two acronyms. Keep in mind that the slow-release is associated with the nitrogen. It is difficult to give you specific recommendations on a fertilizer ratio to use in your yard without knowing what type of soil you have. Soils act as a reservoir for plant nutrients. Utah State University offers soil tests that will help you determine what nutrient load your soil has with regard the phosphorus (P) and potassium (K). A general tests costs approximately $14.00 and you can pick up a kit at any USU Extension Office. I can tell you that typically Utah soils have plenty of P and K. Nitrogen is typically always recommended as an addition each year because plants need it in the greatest quantity and it is also very mobile in the soil.
