1. Corn Hybrids With Contrasting Root Systems: Response To Soil And Fertilizer PhosphorusWith current corn genetic improvements for water-limited scenarios, root system architecture and growth are being considered which may affect overall nutrient uptake particularly for immobile nutrients. The objective of this study was to evaluate plant response and phosphorus uptake with contrasting, generally shallow and generally deep rooted corn hybrids. Over the two years there were a total of seven sites, two sites in 2011 and five sites in 2012. The sites are all rain fed except for three sites... |
2. 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 agricultural... A. Sadeghpour, A.M. Weidhuner, G. Burkett, O. Zandvakili, O. Adeyemi, C. Kula, J. Berberich, J. Pike, A.J. Margenot |
3. Individual Leaf Selection to Best Represent Whole-plant Nutrient Status in Modern Corn Cropping SystemsIn modern corn cropping systems, fertilization is often required to maintain plant health. Tissue sampling is commonly utilized to evaluate plant nutrient status and determine fertilizer treatment needs. Recommendations exist on which partition/leaf to select for accurate representation of the whole-plant. Recommendations change with growth stage, suggesting to sample the whole-plant at early-vegetative stages, the top-collared leaf at late-vegetative stages, and the ear-leaf during reproductive... B.
