Giving Plants More Nutrients With Less Applied Fertilizer

Flavonol Polymer Technology Increases Fertilizer Efficiency

AgroLiquid developed Flavonol Polymer Technology to solve a problem most farmers are familiar with: nutrient tie-up in the soil. After applying literal tons of fertilizer, plants still may not reach their full growth potential. This occurs because most of these nutrients become tied up in the soil before plants can use them. After that, they often end up filtering away into lakes and rivers through rain and snowmelt. Our chelated nutrients use Flavonol Polymer Technology to release slowly and directly to plants, so they are used more efficiently. This means plants use more nutrients, with less soil tie-up and runoff.

Have us design a custom nutrition plan for you

An AgroLiquid nutrition plan is dependent on your location, climate, soil conditions, and goals with your crop. All of our tailored programs start with reviewing your soil samples with one of our expert agronomists. After our analysis, our team will provide you with a couple options that will help you meet your goals on a budget that won’t break the bank.

How it Works

Our Flavonol Polymer Technology is based on specially-formulated plant-based chelates. Chelates protect nutrient atoms like potassium, nitrogen, phosphorus, sulfur and others in a polymer shell. And, because the chelant is plant-derived, the crop recognizes the material and utilizes it, as well. Plants are able to naturally deconstruct this shell. The chelated nutrient fertilizers are protected from bonding with ions in the soil—which makes them unusable to plants—but the plants can still break down the plant-derived polymer shell to get to the nutrients inside. Since the chelated micronutrients and macronutrients break down over time, they’re available to use over a longer period. This means more nutrients for plants and fewer trips for farmers.

Benefits of Flavonol Polymer Technology

  • Make more nutrients available to plants
  • Provide longer-lasting nutrition throughout the growing season
  • Maintain soil health
  • Avoid nutrient toxicity in the soil and water

Flavonol Polymer Technology is the Key Ingredient

Our Flavonol Polymer Technology is the key ingredient in our high-efficiency fertilizers. From our most widely-used macronutrient products to micronutrient blends for specific soil issues, Flavonol Polymer Technology is essential.


Potassium, nitrogen, and phosphorus easily bond with soil ions, so they quickly become tied up in the soil. Flavonol Polymer Technology prevents this through protective plant-based polymer chains. Plants break down these polymers and use the macronutrients, so fewer nutrients are tied up in the soil or end up in the water. Flavonol Polymer Technology is used in all our macronutrient fertilizers, like High NRG-N for nitrogen, Pro-Germinator for phosphorus, and Sure-K for potassium.

Secondary Nutrients

Secondary nutrients like sulfur and magnesium are only needed in small amounts, but this also means they can quickly be tied up in the soil. We use Flavonol Polymer Technology to protect secondary nutrients as well as macro- and micronutrients, to provide a balanced nutrient profile to the soil and plants. Flavonol Polymer Technology is used in all of our secondary nutrient fertilizers, like accesS for sulfur or LiberateCa for calcium.


Micronutrients often bond with macronutrients or secondary nutrients, which is why commodity fertilizers often upset the natural levels of micronutrients. Our chelated micronutrient fertilizer restores these levels and makes micronutrients available to plants. All of our individual and chelated micronutrient fertilizer blend use Flavonol Polymer Technology, including Micro600, Micro500, and Micro400.

Have a specific crop problem you’re trying to solve?

AgroLiquid was founded because there wasn’t a nutritional product that was solving our fertilizer needs; now after 35 years our chemists and biologists continue to innovate and create the best products on the market. If you have a specific crop problem, ask one of our agronomists and we’ll help you solve it!
