15-5-30 Hi-K Fall Blend

SKU: TL07128903

The RichGROW 15-5-30 “Hi-K” standard-sized (240 SGN) blended fertilizer is formulated with slow-release nitrogen for exceptional turf nourishment.

Crafted as a premium-grade solution, this fertilizer is meticulously designed for golf course fairways/roughs, sports fields, and residential lawns. Its composition makes it particularly effective during late summer through fall and serves admirably as a dormant winter feed. Boasting 65% Controlled Release Nitrogen (CRN) sourced from stabilized nitrogen elements, it actively curtails sudden growth spurts while extending the green-up response for an impressive duration of up to 10 weeks.

The CRN feature not only promotes sustained growth but also significantly mitigates nitrogen loss to the atmosphere, diminishing volatilization and nitrate leaching into groundwater. Remarkably adaptable to high Cation Exchange Capacity (CEC) soils like clay, this fertilizer excels in amending low potassium levels, ensuring optimal soil balance.

Enriched with soluble nitrogen from ammonium sulfate, it supplements plants with sulfur, proving more accessible in cooler fall conditions. This blend offers a comprehensive solution to enhance turf vitality and resilience.

Elevate your turf care routine with our 15-5-30 “Hi-K” fertilizer, tailored to deliver sustained nourishment and foster lush, resilient landscapes across golf courses, sports fields, and residential lawns throughout the changing seasons.
