Idaho Potato Trial — +43 CWT Per Acre

Trial Overview:

Multi-year independent field trials on commercial potato operations documented consistent yield improvements when replacing a portion of conventional synthetic fertilizer with OA-Ag carbon-based powder products. The 25% Replacement Program was implemented on drip-irrigated operations, integrating directly into existing fertigation schedules with no equipment changes required.

‍

Program Applied:

The 25% Replacement Program was used, substituting 25–40% of synthetic NPK inputs with V-Series water-soluble powder and OA Liquid NPK. The low salt index formulation (under 18) reduced root zone salt stress while delivering full nutrient availability.

Key Results:

• +43 CWT per acre average yield increase across multiple trial years
• Reduced salt accumulation in root zone beds
• Maintained or reduced total input cost per acre
• 100% water-soluble — no line clogging or compatibility issues
• Soil organic matter measurements improved year-over-year

‍

Takeaway:

Potatoes are highly sensitive to salt stress. Replacing 25–40% of conventional inputs with OA-Ag's low salt index formulation consistently delivered yield improvements while reducing the total fertility cost burden and improving long-term soil health metrics.
