28-4-8 Okanagan Turf

RichGROW Okanagan Turf 28-4-8 is a premium blended fertilizer with a standard granule size (240+ SGN) and slow-release nitrogen to support steady, sustained growth. Specially formulated for golf course fairways, roughs, sports fields, and residential lawns, this fertilizer can be applied throughout the growing season to encourage healthy shoot and root development. With 60% controlled-release nitrogen (CRN) sourced from stabilized forms, Okanagan Turf 28-4-8 minimizes surge growth and extends green-up for up to eight weeks, while also reducing nitrogen losses to the atmosphere and minimizing nitrate leaching. It performs particularly well in clay soils with a high cation exchange capacity (CEC) and contains soluble nitrogen from ammonium sulfate, providing reliable green-up even in cool spring conditions.
