15-2-15 Pro-Balance with 50% SRN is produced from high quality technical and food grade raw materials. 15-2-15 is safe for both turf and horticultural applications, and is a reliable source of both N and K. 15-2-15 contains soluble, readily available potassium for immediate plant uptake to maintain sufficient potassium levels. Nutrients are absorbed both through the leaves and roots. Potassium improves the stand of stalk and increases disease resistance. 15-2-15 provides an optimal 1 to 1 ratio of N and K which is important when turf cannot use high levels of Phosphorus. No special agitation is required. 15-2-15 does not contain chlorides which can cause salt buildup. Potassium is known to improve winter hardiness of turf grass. University research indicates the importance of maintaining good potassium levels as it relates to drought tolerance. Application is suggested where soil levels of potassium are marginal, and annual applications of two pounds of potassium per 1,000 sq. ft. may be required.
The following recommendations are made for warm season, transitional and cool season grasses such as: Bermuda, Bent, Kentucky Blue, Centipede, Perennial Rye, St. Augustine, Bahia and Zoysiagrass. 15-2-15 Pro-Balance is compatible with most other turf insecticides, fungicides and herbicides. 15-2-15 can be used in place of granular and soluble materials, providing a steady, even supply of nutrients.
