Fertigation compatibility: why powder formulations are the future

Fertigation Compatibility: Why Powder Formulations Are the Future

Drip irrigation and micro-sprinkler systems have transformed specialty crop production. They deliver water precisely, reduce disease pressure, and enable split applications that match crop demand through the season. But they only work efficiently when the fertility program runs through the same lines — and most synthetic granular or poorly-soluble products can't make that transition cleanly.

• OA-Ag V-Series NPK Powder is 100% water-soluble — no residue, no line clogging
• FPT Humic Powder dissolves completely for tank mixing and fertigation injection
• FCB Castor Bean Foliar and OA Liquid NPK compatible with all drip and sprinkler systems
• Powder format allows precise dose control and split-application flexibility
• Salt index below 18 eliminates emitter buildup and root zone salt accumulation risk

California strawberry operations spend approximately $977 per acre annually on fertilizer and salt management. OA-Ag's carbon-based program is designed to enter at partial replacement cost parity — matching that spend while reducing salt-related crop stress and building soil over time. The powder and liquid formats are designed for the equipment growers already have.

"What sold me was the salt index data. Under 18 versus 50–105 for synthetics. You can feel the difference in how the plants look mid-season." — Organic Vegetable Grower, Mixed Vegetable Farm, California
