1. Advances in North Dakota Soil Fertility 2022Following years of accumulating data from field studies using the GreenSeeker™ and Holland Scientific Crop Circle™ active optical sensors, algorithms for use in spring wheat for in-season N application for yield, and immediate post-anthesis N application for protein enhancement have been developed. Both algorithms require an N non-limiting area as a standard. The algorithm for protein enhancement considers whether a cultivar has inherent high protein or lower protein characteristi... D.

2. Landscape Position Affects Management Decisions for Crop ProductionLandscape attributes including topographic positions, slope, curvature, elevation, water flow direction and water flow accumulation are well documented in the literature for their effects on crop productivity. Topography influences crop growth and yield by impacting water and nutrient movement in the soil. Under dryland crop production systems, water availability generally depends on topsoil depth, soil organic matter, and curvature of the micro-topography. To improve overall productivity of ... G.

3. N, S and Micronutrient (B + Zn) Interactions in Soft Red Winter Wheat NutritionThis work is intended to answer certain questions that result from the implementation of a multi-element wheat nutrition program. Nitrogen rate is a fundamental driver of wheat yield and quality. However, the impact/value of S or the micronutrients, which are likely components of a more integrated wheat nutrient management program, is not clear.The main study design included 4 rates of N (40, 80, 120 and 160 lb N/acre), 2 rates of S (0 and 10 lb S/acre), and 2 rates of the micronutrient &lsqu...

4. Utilizing Fertilizer and Fungicide Strategies to Enhance Winter Wheat Grain and Straw ProductionThe establishment and overwintering success of Michigan winter wheat (Triticum aestivum L) are often determining yield factors but identifying both autumn and in-season practices that may enhance yield and economic return can be difficult. Additional demand for straw has growers considering inputs that may not only affect grain yield potential but also overall biomass production and serve as another means to improve profitability. Recent research has documented significant grain and ... K. Steinke, L. Suplito, M. Chilvers |
5. Carbon Credit and Sequestration in Agroecosystems; Lessons from Trials in Southern IllinoisA carbon (C) credit is the attribution of net CO2-C equivalent which can be used to decrease climate forcing through a given practice or farming system for a given unit time. Carbon credits allow industries to purchase C that is produced on a farm (i.e., offsets). Carbon can be captured in two ways; (i) by capturing and reducing greenhouse gasses (on a CO2-C equivalent basis), and/or (ii) by increasing soil organic C stocks. Therefore, to enable C credits in the agricult... A. Sadeghpour, A.M. Weidhuner, G. Burkett, O. Zandvakili, O. Adeyemi, C. Kula, J. Berberich, J. Pike, A.J. Margenot |
6. Agronomic Management of Nitrogen to Reduce N2O Emissions in ManitobaNitrous oxide (N2O) emissions from soil accounts for about 20% of Manitoba’s total greenhouse gas (GHG) emissions. Numerous and recent field research has evaluated these emissions as influenced by nitrogen (N) management practices – such as use of enhanced efficiency fertilizers (EEFs), fertilizer placement and timing, use of legume and cover crops and organic farming. Several practices result in considerable decreases in N2O emissions, across a w... J. Heard, M. Tenuta |
7. Cover Crops, Manure, and NitrogenFall seeded cover crops can offer soil and water conservation benefits to dairy-based cropping systems. However, uptake by these fall cover crops can also limit nitrogen availability from the manure to the next crop. Field research projects throughout the state of Wisconsin have been conducted to assess how cover crop specie, biomass, and N uptake influence the amount of supplemental N needed to fertilize the following corn crop to maximize yield. Fall seeded cover crops that winter kill (spr... M. Ruark, A. Waggoner |
8. Pelleted Lime Application Strategies for Iowa Corn and Soybean ProductionResearch has shown inconsistent results about the efficiency of pelleted lime at increasing soil pH or crop yield compared with aglime. Our previous Iowa research (2015-2016) showed that pelleted lime manufactured with limestone from northern Iowa quarries attained maximum soil pH with the same rate and at the same time than finely ground calcium carbonate, but more time was needed for aglime. However, there were no yield differences between the sources for corn-soybean rotations when one-tim... A.P. Mallarino, M.U. Haq |
