1. Impacts from Autumn Starter Fertilizer, Late-season Nitrogen, and Fungicide Timing on Winter Wheat Yield, Straw, and QualityIncreased demand for winter wheat (Triticum aestivum L.) and climate uncertainties have Michigan growers exploring intensive management strategies to improve both yield and profitability. Field studies investigated the influence of both early and late-season fertilizer applications with multiple fungicide timings on the yield and quality of winter wheat grain and straw. A full-factorial, randomized complete block design investigated two rates of autumn starter fertilizer (AS) (12-40-... K. Steinke, M.K. Suplito, M. Chilvers |
2. Soil Carbon Additions Improve Soil Nutrient Cycling and Yield of CornIncreasing soil organic matter and the associated soil carbon is known to positively influence nutrient cycling, and agronomic practices such as conservation tillage and cover crops can facilitate soil carbon increases in the long term. Alternatively, the direct addition of carbon amendments to the soil may serve as an alternative solution for enhancing nutrient cycling in the short-term, which was the basis for this research. Our objective was to assess the potential of granular carbon amend... D. Danzl, D. Below, D. Sible |
3. Beyond the Acre Furrow Slice: a New Era in Nutrient ManagementThe Midwest faces a pivotal shift in how we develop nutrient guidance for farmers. The long-running “build-up and maintenance” approach, built on decades-old soil-test methods, no longer aligns with today’s diverse and dynamic farming systems. Instead of anchoring decisions to soil depths tied to historical moldboard plow use, we should emphasize soil supply and plant uptake over time. Recommendations must be grounded in actual nutrient removal at harvest, on a site-by-... H.M. Brown |
4. The Future of Soil Fertility - My Two CentsThis presentation will provide information of what a large cooperative is currently providing customers in the realm of nutrient management. Additionally, some insight will be provided on how other aspects of nutrient management (global markets, production technologies, etc) are being evaluated. Finally, some general ideas will be shared regarding the future needs of the retail sector along with some research ideas. ... R. Mullen |
5. Evaluating Spatial Attribution for Continuous Improvement of Fertilizer RecommendationsThe theory behind precision agriculture is driven on the improvement of every acre. While spatially driven recommendations have been practiced for greater than 30 years, the benefits of precision agriculture have largely not been realized. Today’s precision fertilizer recommendations have generally utilized traditional attributes (for instance: soil test phosphorus, soil test potassium, and in some application recommendations, other analyzed attributes from soil test evaluat...

6. Technology, Innovation, and the Future of Soil FertilityThis panel will focused on how technology is being used in the practice of soil fertility and nutrient management. Panelists will also discuss how they’ve incorporated new and old soil fertility concepts into their approach to guiding fertilizer use. Lastly, we will discuss where soil fertility is going as a scientific discipline. ... H.M. Brown, W. Berg, R. Mullen |
7. Nitrogen Fertilizer Application Consultation Tool (N-FACT)The N-FACT is a decision support web tool that leverages data from the Iowa Nitrogen Initiative on-farm nitrogen rate trials with cropping systems modeling. The web tool was released in February 2025 (https://n-fact.ag/start). The web tool summarizes results on optimum nitrogen fertilizer rate for corn from hundreds of on-farm trials across Iowa. Additionally, the web tool allows users to select a county, crop rotation, planting date, fall... S. Archontoulis |
