Continuous No-till Management: Implications for Soil Quality, Carbon Sequestration, and Nitrogen Conservation
… were to: i) quantify C sequestration rate and N conservation with duration of continuous no-till; ii) measure C stratification with continuous no-till as an indicator of soil quality; and iii) evaluate the Illinois soil N test (ISNT) for its value to predict fertilizer N needs of corn in …

Effects of Elevated Atmospheric CO2 on Root Growth, Turnover and Decomposition in a Scrub Oak Ecosystem
… mass had been lost after 828 days. A period of nitrogen immobilization occurred in both fine roots and rhizomes in the elevated CO<sub>2 </sub>treatment, which is potentially a mechanism for nitrogen conservation for this system in an elevated CO<sub>2 </sub>world. Significant fine root …

Conservation of Nitrogen via Nitrification and Chemical Phosphorus Removal for Liquid Dairy Manure
… aeration strategy that could be used to conserve nitrogen (N) via nitrification in dairy manure, (2) determine the effect of recycled flush water on the bio-availability of N during nitrification, and (3) determine effective and economical dosages of chemicals to remove phosphorus (P) from liquid …

Evaluating Crop Physiological and Stand Age-Related Controls Over Soil Carbon and Nitrogen Dynamics In Perennial and Annual Grains
… how the cycling of carbon (C) and fertilizer nitrogen (N) between crop tissues and soil pools is expressed in perennial grains such as intermediate wheatgrass (IWG, Thinopyrum intermedium (Host) Barkworth and Dewey), and whether these processes change within a growing season and across IWG …
