Technology continues to advance regarding data imagery, visualization and modeling Intensive soil testing can improve nutrient management Soil testing remains one of the most cost-effective methods for farmers and ag retail advisors to optimize ROI while avoiding unneeded nutrient applications. With wheat harvest wrapping up, these harvested fields are prime areas for grid or zone sampling plans that can identify nutrient variability within the field. Areas of fields with deficient nutrient levels can be located and be brought up to sufficient levels, boosting yield potential. Identifying areas with excess nutrient levels offers the opportunity to reduce nutrient application rates in those areas, while still maintaining full yield potential. The cost of a soil testing program, as a result, is well worth it in terms of the full range of economic benefits back to the farm business. There continue to be substantial environmental benefits to soil testing, which supports farmers’ ongoing efforts to protect soil health and water quality. Soil testing promotes strong on-farm stewardship by optimizing nutrient use and avoiding runoff. Both of these benefits are enhanced by the continued advance of technology. One of the most exciting elements of modern agriculture is the pace at which visualization and modeling based on gathered data can benefit on-farm decision making. This holds true with soil testing data. Modern variable rate application equipment can utilize the data layers generated by intensive soil sampling to precisely apply prescribed fertilizer rates on a sub-acre basis. Ag retail advisors – including more than 300 Certified Crop Advisers across Michigan – can work with farmers to help them craft a soil testing program tailored to their business. Managing these open wheat fields into the fall benefits from a cost-effective soil testing program, with intensive soil testing offering the opportunity to benefit farm economics in both the short and long-term.
