CultivAce Acetate Fertilizers
5% Calcium Acetate
Plants need a continuous supply of calcium to maximize growth. By adding calcium, the plant cell wall strengthens to help prevent the fruit from breaking down in storage. CultivAce CaAce acetate decreases the likelihood of fruit spoilage, improving shelf life and market value.
14% Potassium, 2% Mn Acetate Fertilizer
K Ace+Mn combines 14% potassium and 2% manganese in highly available acetate forms to deliver a 2-in-1 application, supporting photosynthesis, water regulation, nitrogen metabolism, seed development, and better sugar/carbohydrate production.
9% Ammonium Acetate Fertilizer
The easiest way to improve a plant’s reproductive function is to stimulate ammonium nitrogen growth in the plant. CultivAce NH4-Ace does just that. It can be used for all crops and has been proven to yield amazing results, every time.
Zinc Acetate Fertilizer
When you fertilize with high rates of phosphorus, zinc becomes less available in plants. To aid the production of auxins, root formations, and influence the rate of seed and stalk formation, Zn-Ace is the acetate fertilizer that is ideal for all crops.
Colbalt & Molybdenum Acetate Fertilizer
CoAce+Mo combines 2% cobalt and 3% molybdenum in acetate form to correct nutrient deficiencies and support efficient nitrogen fixation in legumes and specialty crops. This highly available liquid fertilizer promotes stronger nodulation, protein formation, early vegetative growth, and overall crop vigor.
5% Magnesium Acetate Fertilizer
MgAce facilitates the distribution of phosphorus through the plant. Since P is essential for developing flowers, fruit, and roots, a lack of magnesium results in plants that fail to produce fruit and stops their ability to take in enough other nutrients.
5% Nickel Acetate Fertilizer
NiAce is a 5% nickel acetate liquid fertilizer formulated to correct nickel deficiencies and improve nitrogen utilization in crops. Its highly available acetate form supports healthy plant metabolism, seed development, and stronger performance in legumes, high-organic-matter soils, and urea-based fertility programs.
Zinc + Manganese Acetate Fertilizer
ZnAce+Mn combines 4% zinc and 2.5% manganese in highly available acetate forms to correct micronutrient deficiencies with one convenient foliar application. It supports root development, photosynthesis, nitrogen assimilation, sugar production, seed formation.
5% Iron Acetate Fertilizer
Chlorophyll production is essential to plant health. Without iron to deliver the nutrients for chlorophyll production, plant respiration, and metabolism you’ll have average growth with average yield. The FeAce acetate fertilizer gives plants the iron they need to maximize yield, especially in higher pH soils.
5% Manganese Acetate Fertilizer
Soils with higher pH often have less manganese to enhance plant reproduction and seed production. The CultivAce MnAce acetate fertilizer makes sure that doesn’t happen by making manganese directly available to the plant.
Nickel + Copper + Molybdenum Acetate Fertilizer
2% cobalt, 3% molybdenum, and 0.75% nickel in highly available forms to support efficient foliar uptake and correct key micronutrient deficiencies. Targeted formulation promotes nitrogen fixation, nitrate reduction, protein synthesis, stronger nodulation, and improved nutrient utilization.
5% Calcium+Boron Acetate
CaAce+B is a great foliar application option for calcium and boron. This foliar fertilizer is crafted from Calcium Acetate and Boric Acid. Formulated for plant nutrition, it features 5% calcium and boron, vital micronutrients for plant health and improved crop quality and yield.
5% Colbalt Acetate
CoAce is a 5% cobalt acetate liquid fertilizer designed to correct cobalt deficiencies and deliver highly available nutrition for efficient plant uptake. Ideal for soybeans, alfalfa, and other legumes, it supports biological nitrogen fixation, balanced plant metabolism, and stronger crop performance.
10% Copper Acetate Fertilizer
Increasing nitrogen applications reduce copper uptake from the soil. Copper is essential for pollen formation and improving the ability to transfer essential nutrients throughout a plant. The CuACE 10FL acetate fertilizer replenishes the much-needed copper a plant isn’t getting from the soil.
23% Potassium Acetate Fertilizer
Increased sugar and carbohydrate production as well as transporting water within a plant comes from just the right amount of potassium. When KAce is applied at the right plant growth stage, the needed K for each plant helps improve the ability to transport those nutrients.
Acetate Fertilizer Trials
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.
