Liquid Fertilizer vs Dry (Solid) Fertilizer

Starting out as two brothers on a mission to better manufacture clear liquid fertilizers, Twin State, Inc. is now the biggest U.S. advocate for liquid fertilizers. Here’s why.

Nutrient Combining

A feat nearly impossible for their dry counterparts, liquid fertilizer can combine specific nutrients needed for diversified row crops. Save time and labor costs by combining nutrients and reducing the number of application trips.

Uniform Composition

Each drop of liquid fertilizer contains the exact same amount and ratio of crop nutrients for the intended plant.

Superior Placement

Your cropping systems are ever-changing and liquid fertilizer allows for maximum application flexibility and use for the growing plant. Some call this being “spoon-fed” and that’s a good thing (in this case, anyway)!

Absorption Efficiency

Liquid fertilizer is better absorbed into the plant.


Liquid fertilizers can also adapt to the size of your field.

Reduced Cost

Reduced material handling and application costs.

Manufacturing & Supply

Proven Track Record

Incorporated in 1958, we operate as a privately held Iowa corporation. We have three major manufacturing facilities:

We are constantly evaluating our manufacturing processes in a consistent manner to bring you an affordable and effective product. If your goal is to have strong ROI year in and year out, we are the liquid fertilizer manufacturer for you.

Our distribution system has evolved whereby nitrogen solutions and concentrated solutions of phosphate, potash, and sulfur are shipped to more than 100 independent and cooperative dealer locations for further mixing to meet the growers’ needs. All of these products travel to the market under the trademark Liqui-Grow.

The Agronology Research Center regularly publishes research bulletins to provide farmers with relevant data to select the right fertilizer, at the right rate, in the right place, and at the right time. These reports can be utilized to make informed decisions about your fertility needs and help increase your profitability per acre.

Keep in mind that, you also have us as your trusted wholesale fertilizer supplier partners. To learn more about our product line, contact one of our Twin State sales representatives.

Twin State Advantage

We believe in face-to-face business with a firm handshake. We build relationships and still remember our first customer to this day. We started in our basement in Bettendorf, IA and watered our own soil until we found a way to help you. To give you a little background, Twin State was always interested in research and looking for ways to enhance the performance of our fertilizers to the benefit of the farmer. Below is a shortened timeline of the education and resourcing we took on in the early days to ensure your needs would be sufficiently met for years to come.
