Carbon-based foliar nutrition
O'444 Foliar Fertilizer
O'444 foliar fertilizer is a carbon-based product pathway in the ProGreen Ag catalog. Use this page to connect the product with approved documents, related crop programs and a verified purchasing conversation.
What is O'444?
O'444 is positioned as a carbon-based foliar fertilizer for use within a complete crop nutrition program. The product name and category are confirmed; guaranteed analysis, labeled crops and rates publish only from the current approved label.
The intended product story centers on carbon-supported foliar nutrition. The exact composition and any performance statement remain approval-gated so the published explanation cannot outrun the source document.
Label, analysis and application guidance
Guaranteed analysis, rates, timing, labeled crops and tank-mix directions appear only when ProGreen Ag has recorded an approved source. This prevents a product name or old document from becoming field guidance.
Current label guidance is available on request.
No approved analysis, application rate, timing or tank-mix direction is published for this product yet. Ask for the current label and identify the crop, acreage, location and planned application.
