ZAV Terra Start-NP is a highly specialized granular base fertilizer formulated exclusively to prioritize massive root development without promoting excessive, soft vegetative top-growth. It is the absolute fertilizer of choice for soils that already hold adequate Potassium but are naturally deficient in Phosphorus. It is particularly crucial for winter-sown cereals (wheat, barley) and early orchard plantings, where a deep, aggressive root system is the only way the plant will survive the harsh winter and thrive in the spring.
