Precision Sensing Equipment Developed at Oklahoma State University

Dr. Marvin Stone, Dr. John Solie, and Dr. Bill Raun have many patents on active sensing technology and N application equipment (OSU-VRT team) that has increased NUE for corn and wheat (started 1992).

OSU Engineering and Plant and Soil Science Faculty develop the next generation VRT applicator for research in wheat, corn, soybeans, canola, sorghum, and bermudagrass
 

The Next Generation VRT applicator developed by OSU Engineering includes application in corn, wheat, soybeans, sorghum, canola, and bermudagrass.  This unit is capable of foliar nutrient sprays while simultaneously applying N in liquid streams.  Also, the new applicator at OSU focuses on new sensing technologies that measure plant height, and plant vigor in addition to NDVI measured with the GreenSeeker sensor that is an excellent estimate of plant biomass.
