How Fertilizer Feeds Turf
The main course for turf is the fertilizer's Nitrogen-Phosphorus-Potassium (N-P-K) formula. However, there's also a variety of secondary and micronutrients needed to keep turf healthy and growing - Calcium, Magnesium, Sulfur, Iron, Manganese, Zinc, Copper, and Chlorine.

Granular fertilizers can contain a blend of nutrient particles, as in LESCO PolyPlus, or each homogenous particle can be comprised of all the nutrients, as in LESCO NOVEX. LESCO PolyVex uses both approaches; it contains a blend of different nutrient particles and individual homogenous particle nutrients.

Nutrient Release
The nutrients in the fertilizer are made accessible to the plant throught a number of natural release mechanisms -- Microbial Action and Soil Temperature; Osmosis; Hydrolysis; and Physical Breakdown. As the structure of the fertilizer pellet melts away, minerals are released into the soil and absorbed by the plant.
