Okanagan GrapeGrow North 15-10-15 50% SN

Okanagan GrapeGrow North was developed as a fertilizer for general grape production in the northern Okanagan Valley and South Thompson regions of BC. Stabilized release nitrogen is used in this blend to minimize volatilization and nutrient leaching while ensuring a constant supply of nitrogen for plant growth. Over fifty percent of the potash is provided in the sulphate form to minimize chlorides and keep the salt index down. The addition of boron makes this a good choice on alkaline soils where boron availability is often limited but necessary to support fruit set. Zinc plays significant roles in leaf development and plant growth. The manganese in this fertilizer blend will assist the plant in metabolizing nitrogen.
