The Rainbow Story
The story of Rainbow Plant Food is an age-old tale of people, technology and chemistry. From the material on this page, you can learn about how we employ the smartest scientists, implement the latest technology, and rely upon a patented process to mix minerals and nutrients into the best fertilizer money can buy.

First, of course, are details about Rainbow itself – a history that begins before movies had sound. Here you’ll find out about International Agriculture Corporation, the company that invented Rainbow Plant Food, and about Dr. R.P. Thomas, Ph.D., the man who made Rainbow what it is today.

Next is information about our granular approach. Each of our granules is a complete package of the nutrients you need for healthy crops. Our granules are homogeneous – uniform in size, shape, and weight – so they spread evenly to maximize distribution. These granules also deliver the proper nutrient amount within the all-important root zone, giving your crops the best of what they need, every single time you spread. Together, these benefits comprise what we call the “Granular Advantage,” a strategy that sets Rainbow Plant Food apart from all of our competitors.

Finally, you’ll find research that establishes formally why Rainbow Plant Food is the best fertilizer money can buy. This research, conducted recently by researchers at a leading university, states plainly that while blended fertilizer is good, the benefits of granular fertilizer, such as Rainbow Plant Food, are worth a look.

When you’re finished here, you are on your way to knowing everything there is to know about Rainbow Plant Food. Enjoy!
