Quality Control

Ensuring Our Products and Services
Are Always As Good As They Can Be

A most important factor is the confidence our growers have in the JR PETERS Laboratory and the Jack's line of fertilizer products. They know that we have been specializing in testing for commercial horticultural crops for over 6 decades. Our three-generation family company knows what has to be done to make the highest quality, innovative fertilizers and consistent lab results. This means performance over an extended period, not just for a crop or two.
