What is the Right Phosphorus Starter Fertilizer?
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.
Nutrient Efficiency: The Dual Benefits of CultivAce Acetates and Free Phos 24
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.
