7-6-6 Hi Iron

RichGROW 7-6-6 Hi Iron is a micro-sized (100 SGN) homogeneous fertilizer formulated with organic slow-release nitrogen from soybean meal, designed for closely mowed turf on golf course greens and tees. Its small particle size and uniform composition ensure even nutrient distribution across the putting surface. The 30% Controlled Release Nitrogen (CRN) from organic sources minimizes surge growth, extends the green-up response, and reduces nitrogen loss through volatilization and nitrate leaching. Iron at 7% promotes deep green colour without stimulating excessive top growth, making this an effective all-season baseline for foliar and liquid programs. Calcium (Ca) and iron (Fe) support cell wall structure and chlorophyll production; manganese (Mn) and zinc (Zn) contribute to disease resistance. Organic matter supports beneficial soil microorganism populations, humic acids aid nutrient uptake, and kelp meal acts as a biostimulant for both root and shoot development. Documentation Tech Sheet
