NPK 19-19-19 Water-Soluble Fertigation Blend

Overview

NPK 19-19-19 is a fully water-soluble, balanced fertilizer blend formulated for dissolved delivery through irrigation systems. Its near-equal nitrogen, phosphorus, and potassium content makes it a versatile base formulation for growers running structured fertigation programs, where nutrients are delivered in small, frequent doses alongside irrigation water rather than as bulk soil applications.

When to Use It

This blend is well suited to greenhouse vegetables, orchards, and coffee production, where drip or micro-irrigation infrastructure is already in place and growers want precise, frequent control over nutrient delivery. It is typically used as a general-purpose base blend through vegetative and early reproductive stages, often complemented by more targeted formulations later in the crop cycle.

Application Guidance

Because fertigation relies on full dissolution and consistent water quality, buyers should confirm compatibility with their irrigation water and injection equipment before scaling up use. As with all our formulations, batch documentation supporting this compatibility check is available — see our Certifications & Quality page for how we handle testing and traceability. As a general reference, growers commonly dose within the range noted above, adjusted for crop stage, irrigation frequency, and local water analysis.
