Water Quality Study

Soil Doctor® System

Official
Water Quality Study

From 1993 to 1995, the USDA's Agricultural Research Service (ARS) office in Urbana, IL conducted water quality studies to ascertain the environmental impact, if any, from using CTI's Soil Doctor® Nitrogen Applicator.

Two farms were chosen. One is a No-Till farm in Shirley, IL, just twenty miles south of Bloomington. There Mr. J. T. Schneider's operation has been relying upon the CTI Precision System to purposely, unevenly distribute nitrogen fertilizer, foot-to-foot, since 1987. The other farm is a No-Till farm in Lexington, IL, just 10 miles north of Bloomington. That farm has never relied upon the CTI System to distribute nitrogen fertilizer.

CTI has been told that the water quality results from the first farm repeatedly tested amazingly clean, even though those fields produce better than average yields and even though No-Till (which is great for protecting top soil) is believed to exacerbate water contamination problems by nitrate. CTI has also been told that the water quality results from the second farm repeatedly tested very high in nitrate.

It is believed that the Illinois study is the Only Water Quality Study in the World which validates the environmental benefits of any Precision Agriculture technology currently in existence.

ARS HAS NOT RELEASED THAT DATA, and has offered no explanation for sitting on that data, despite repeated requests.
