Slow-release nitrogen (N) sources, also called “slowly available,” are a part of many turfgrass fertilization programs. They provide greater longevities of available N than quick-release sources, and are safer to use on turfgrass because of their lower burn potential. This group includes both coated and uncoated sources.
Has the highest nitrogen (N) content (43%) and lowest sulfur content (4%) of any polymer-coated sulfur-coated urea (PCSCU) on the market; provides gradual, steady nutritional uptake for up to 10 weeks of plant response.
A patented, liquid nutrient source designed for foliar applications in turfgrass, row crops, vegetables and fruits.
This methylene urea (MU) source provides consistent, long-lasting nutrient release for up to 16 weeks; delivers a cost-effective, low-maintenance solution to effectively increase root growth.
A urea-formaldehyde (UF) fertilizer specially developed to deliver a steady, balanced and dependable source of N for up to 22 weeks or more.
