GSR Tri-Phase is an 18-3.5-8 NPK organic-based, phased-release fertiliser which provides up to five months’ worth of nutrients and trace elements from a single application at a budget-friendly price.
GSR Tri-Phase also supplies one unit of MgO plus trace elements including copper, zinc, boron, manganese and molybdenum.
Recommended for use on all fine grass swards including golf greens, tees and fairways, sports pitches and all amenity areas, GSR Tri-Phase’s mini-granular (1-2mm) formulation delivers a cost-effective and consistent supply of nitrogen and potash over a period of 16-20 weeks.
GSR Tri-Phase contains three forms of nitrogen to provide three phases of nutrient release into the rootzone: an initial hit of quick release nitrogen gives way to methylene urea which is subsequently followed by a final release of organic based nitrogen. In addition, potash is also released slowly throughout the growing season to regulate water uptake and to ensure nutrients and trace elements remain mobile and available for uptake. This not only reduces plant stress throughout the growing season, but also enhances the sward’s ability to withstand drought conditions.
