A 2-year project in Northwest Ohio measured the impact that soil conservation practices have on selected soil health indicators and the subsequent corn yield in cover cropped hay, wheat and corn cropping systems. When choosing which test to conduct, factors such as time, cost, and training need to be considered. The field test cost per sample is approximately $40 less than the burst test however the digital color reader will increase one time costs for field testing by up to $900 (www.solvita.com). Accuracy of results is dependent on proper sample collection and testing for both methods. A one-time measurement of soil indicators may lead to false conclusions. Multi-seasonal, multi-year and replicated measurements are needed to accurately measure soil biological activity under various soil temperature and moisture conditions.
