Fertilizer Trials
CultivAce is committed to continuous improvement and innovation in agricultural nutrition. Our fertilizer trials are an essential part of our research and development process. We conduct rigorous and scientifically-backed trials to test our fertilizers' effectiveness on different crops and under various growing conditions.
Through our fertilizer trials, we aim to fine-tune our products to ensure we meet the unique needs of different crops and provide optimal results for farmers. These trials allow us to gather valuable data on crop responses to our fertilizers, nutrient uptake, yield potential, and overall crop performance.
We collaborate with growers and research partners to conduct field trials that mimic real-world conditions. By analyzing the data obtained from these trials, we can make data-driven decisions to enhance our liquid micronutrient fertilizers and create custom solutions for specific crop requirements.
3rd Party & University
Fertilizer Trials
2025 North Dakota State University
FeAce SoyBean Trial
FeAce delivered up to 91% more iron than the untreated control and 49% more than EDDHA just 3 days after application.
2024 California 3rd Party
Trial with MnAce
MnAce increased tissue manganese by 28% over amino acid chelate and 29% over EDTA, proving acetate’s efficiency.
2024 Iron Acetate Foliar
Application 3rd Party Trial
FeAce raised tissue iron by 54% over EDDHA, delivering faster, more efficient foliar iron uptake even in high-pH soils.
2024 Zinc Acetate Foliar
Application 3rd Party Trial
Zinc Acetate outperformed zinc nitrate by 26% and zinc amino acid by 60%, with a 151% gain over the untreated check.
2023 Zinc Acetate Foliar
Application 3rd Party Trial
Zinc Acetate boosted tissue zinc by 142% over EDTA and 158% over the untreated check, proving its superior foliar uptake.
Free Phos 24 Trials
Acetate Fertilizer Trials
In a head-to-head comparison, MnAce (5% Manganese Acetate) outperformed manganese sulfate in soybeans, raising tissue manganese concentrations by up to 67% in individual reps and delivering an overall +37% composite increase. The results highlight the superior uptake efficiency of acetate-based foliar nutrition.
2025 Indiana Manganese Soybean
Foliar Comparison Trial
2025 California Magnesium
Grape Foliar Comparison Trial
In Bakersfield, California, we put up MgAce, our 5% magnesium acetate, head to head with a magnesium dextrose competitive product. MgAce increased magnesium uptake by 9%.
A foliar trial in Newberg, Oregon demonstrated CuAce's rapid efficacy in correcting copper deficiency in hazelnuts. After 1 application of 2 quarts per acre, leaf sap copper levels increase in just 3 days.
2025 Newberg, Oregon CuAce
Hazelnut Foliar Trial
2025 Indiana Zinc
Foliar Tissue Trial
In South Bend, Indiana, this Zinc Tissue Trial was conducted on over 240 acres. Using just one quart/acre of ZnAce, the grower saw a 93% & 253% increase just 5 days after application.
2024 California K Ace &
Free Phos 24 Tomato Trial
Using just 1/10th the fertilizer, the K-Ace + Free Phos program delivered 1.67 more tons/acre than the standard.
2024 South Bend, Indiana
SoyBean Trial with MnAce
MnAce corrected manganese deficiency where EDTA failed, increasing tissue levels by 15% into the sufficiency range.
