40-0-0 Methylene 80 Greens Grade

40-0-0 is a micro-sized (90 SGN) single-nutrient, premium fertilizer made from 100% methylene urea(s). Designed for use on closely mowed turf grass such as golf course greens and tees. Its small particle size provides even distribution of nutrients. 40-0-0 is one of the most commonly used controlled-release nitrogen (CRN) sources used on professionally managed turf. Methylene urea relies on temperature, moisture and microbial activity to become plant available. These 3 mechanisms ensure that it does not over-release or 'spike' at any one point in time. The result is a very safe, gradual supply of nitrogen throughout the growing season. Ideally used in northern climates during summer and fall/winter months. Fall/winter applications build carbohydrate reserves for the following season's spring growth.
