Tri-Flo has been providing Variable Rate Technology (VRT) sampling since 2008 and truly believes it is an essential building block of a sound fertility program. With the ability to sample by soil type, yield map, or management zones we are able to pinpoint fertility issues within the field. After receiving sample results back from our trusted lab, we are able to use the information to develop effective variable rat fertilizer and lime recommendations. For more information about how you can utilize VRT sampling to benefit your operation give us a call!
