A 5 gallon 40-year-old container of 5-10-5 NACHURS liquid fertilizer was discovered tucked away in a corner of the Wheatland Mill and Elevator Company in Wheatland, Iowa. In front of an audience, the seal was broken and a clear premium liquid fertilizer poured evenly and cleanly from the can. It was almost as if the fertilizer had been put in a time capsule. Steve Keller, Nachurs Alpine Solutions former chemist, examined the fertilizer and concluded that the fertilizer is as good today as it was 40 years ago. A lot of liquid fertilizers would have settled out after a short period of time. The high purity of raw materials and the near neutral pH prevented the 5-10-5 analysis from settling out.

It's this level of quality that makes us proud to offer our customers Nachurs Fertilizer, give us a call to help pick the right fertilizer for your application.
