Fertilizer labels function as legal disclosures rather than marketing copy. Sta-Green Performance Max typically carries an NPK fertilizer ratio centered on a high-nitrogen profile such as 28-0-4 or 30-0-3, depending on regional phosphate regulations. That initial number indicates 28% to 30% total nitrogen by weight, an essential macro-nutrient driving vegetative canopy growth and chlorophyll production. Zero phosphorus responds directly to municipal water protection standards prohibiting runoff into local watersheds, while the final digit represents soluble potassium to support cellular wall strength and drought tolerance.

The critical metric rests inside the fine print beneath the primary ratio: the slow-release nitrogen percentage. Sta-Green relies on polymer-coated sulfur-coated urea (PCSCU) for roughly 30% to 35% of its total nitrogen package. The remaining 65% to 70% comes from quick-release urea and ammoniacal sources. This split explains why the product generates visual lawn green-up results within four to six days after watering. The fast-acting urea dissolves quickly into the soil solution, triggering rapid greening, while the coated spheres break down gradually through microbial activity and ambient moisture to sustain steady color across roughly two months.
