Not all phosphorus starter fertilizer performs the same once it hits the soil. In a 2025 Minnesota corn trial, a program using 15% less P₂O₅ still out-yielded a higher rate by 14 bushels per acre. The difference wasn’t how much phosphorus was applied, it was how effectively it was used.
This is where phosphorus fertilizer management (PFM) changes the conversation, shifting focus from volume to availability, and showing how stronger early-season efficiency can translate into measurable gains at harvest.
As winter sets in and fields slow down, it’s a good time to revisit the nutrients that quietly shape yield long before harvest. Copper may be a micronutrient, but overlooking it can haunt a fertility program in much bigger ways than most growers expect. Like Scrooge in A Christmas Carol, it’s often the small, ignored details that come back to matter most.
Copper acetate foliar fertilizer represents a modern shift in how copper is delivered. By bypassing soil tie-up and delivering copper directly through the leaf in a highly available form, copper acetate helps crops access what they need when timing matters most. Recent on-farm and third-party trials have shown copper acetate dramatically improving tissue copper levels and outperforming traditional EDTA and amino acid sources, reinforcing that form and delivery can make all the difference.
Sometimes, the biggest improvements don’t come from adding more inputs, but from choosing a better one.
At the North Dakota State University Potato Field Day, growers couldn’t stop talking about CultivAce’s starter fertilizer for potatoes, powered by PFM. Early trial digs revealed stronger stands, deeper roots, and faster establishment compared to traditional 10-34-0 programs. Backed by years of field-proven data, CultivAce’s 8-24-0 starter is redefining early-season nutrition with higher phosphorus efficiency, reduced salt risk, and measurable yield gains across every trial.
When a grower in Indiana saw a 245% zinc uptake using ZnAce, it proved just how effective liquid micronutrient fertilizers can be. Here’s why it worked—and what it means for your next foliar pass.
In California trials, Free Phos 24 delivered 8% higher yields and better ROI than standard 9-24-3 liquid phosphate fertilizer—using 40% less product. Learn how this enhanced-efficiency solution is helping growers do more with less.
CultivAce acetate fertilizers aren’t just for foliar applications—they’re proving to be just as effective in soil applications. Recent trials showed that our ZnAce (8% zinc acetate) outperformed both zinc sugar alcohol and Zinc EDTA in increasing tissue zinc concentration by up to 100%. This supports the dual benefit of CultivAce acetates, working effectively in both the soil and on the foliage.
In a separate trial, our Free Phos 24 liquid phosphate fertilizer, applied at just 3 gallons per acre, demonstrated a significant boost in yields—up to 14 bushels more than the grower’s standard. With reduced input, less fuel, and more acres covered, Free Phos 24 proves that efficiency and high yield aren’t mutually exclusive.
By encouraging microbial processes like phosphate mineralization and solubilization, Free Phos 24 allows plants to access more phosphorus from the soil, reducing the need for excessive nutrient applications and increasing sustainability.
Minnesota’s sugar beets have seen a surprising boost this season, with liquid phosphate and acetate foliar fertilizers making a noticeable difference. Recent trials highlight the contrast between untreated crops and those benefiting from Free Phos 24, showing how these fertilizers can quietly, but significantly, improve both yield and sugar content. Here's what the latest results are showing.
Liquid micronutrient fertilizer foliar sprays are the overlooked MVPs in yield optimization. See how acetate-based formulas drive crop performance and nutrient efficiency.
