1. Fertilizer Manufacture - Converting Nature's Nutrient Storehouse to Plant NutritionNorth American farmers rely on reliable supply of key fertilizer inputs to maintain productivity and profitability. Nitrogen fertilizers are produced from atmospheric nitrogen gas, while phosphate and potash fertilizers are mined from major North American deposits as well as others around the world. All the major fertilizers are supplied, in large part, by North American producers from domestic production supplemented by some imports from international producers. Nitrogen production... A.

2. The Ammonia RainbowAgriculture has been identified as a major contributor to atmospheric carbon dioxide with nitrogen fertilizer production as a key component. Recent scrutiny of nitrogen production processes has identified ammonia production processes to reduce carbon output from traditional Haber-Bosch processes. These different ammonia production processes are often described with color descriptions to designate the processes used and qualitatively identify their carbon footprint, such as “green ammonia”,...

3. Fertilizer Industry Update – Markets, Trends, and New DirectionsThe fertilizer industry was characterized, perhaps above all else, as volatile. We saw near record prices as supply chains were affected by war in Ukraine, international sanctions, and high production costs. Across the industry, fertilizer manufacturers and suppliers seek to cut operating costs to cope with rapidly falling prices. We will review key market drivers and other industry trends. ... A.

4. Nitrogen Fertilizer Rates and Nitrification Inhibitor Impact Agronomic and Economic Returns in Corn Production in KansasNitrogen (N) is an essential nutrient for corn crop, higher grain yields are related to N fertilizer application. Substances like the nitrification inhibitors (NI) were created to increase yields, promote Nitrogen Use Efficiency (NUE), and reduce N losses. The study was carried out in ten site-years in Kansas during 2017, 2018, 2019, 2020 and 2021 crop seasons, with the objective of evaluate the Nitrogen Agronomic Efficiency (NAE) in corn with and without the use of NI and to compare corn grain...

5. Tillage, Cereal Rye Cover Crop, and N Placement Effects on Corn and SoybeanAlthough conservation tillage and cover crops can improve soil health, producers are hesitant to adopt these practices due to concerns about potential yield reductions. We conducted field experiments for four years (2020-2023) near Urbana, Illinois, to explore how these practices affected corn and soybean yields. The experiment was conducted on a Flanagan silt loam soil, with corn and soybean following one another on two sides of the same field. Treatments were arranged in a RCBD with four replications.... F.

6. Management Practices to Minimize Edge-of-Field Phosphorus LossManaging agricultural phosphorus (P) loss at the edge-of-field is critically important to inhibit the development of algal blooms in freshwater bodies. This is particularly important in the Northern Central region which has an abundance of freshwater lakes, agricultural lands, and harmful algal blooms. Edge-of-field monitoring data allows us to take a broad look at how management affects P export from cropland. Looking across a region over several decades also allows us to evaluate the non-management... L. Pease |
