Characterization of Newly Immobilized Nitrogen-15 in a Typical Illinois Mollisol
Turnover of N through mineralization-immobilization leads to incorporation of fertilizer N into organic forms. In time, part of the immobilized N is converted into biologically resistant humus forms. Attempts to characterize the stabilized N have been unsuccessful, partly because the procedures …

Greenhouse gas emissions from production of Miscanthus x giganteus on a Mollisol
… of M. x giganteus on a central Illinois Mollisol. The study had twelve, 10x10 m plots organized in four replicate rows with each of the three N fertilizer treatments placed randomly in each row. Gas samples to determine N2O and CO2 fluxes were taken near noon throughout the year …

Managing Continuous Corn for Yield and Soil Productivity
… Across four N fertilizer rates and five Mollisol environments with abundant rainfall, grain yield with no till improved as residue removal increased, and equaled that of the chisel plow tillage system when all residue was removed. Across tillage systems in these environments, the response …

Seasonal and site relationships to acetylene reduction by actinorhizal black alder and Russian olive root nodules
… (Elaeagnus angustifolia L.) on a bottomland Mollisol increased exponentially with soil temperature. Soil moisture content, pH and nitrogen concentration and leaf nitrogen concentration were not correlated with ARA. Soil pH and nitrogen concentration did not change with season. Bottomland soil …

Land-use change effects on soil organic carbon, total soil nitrogen, and soil erosion in a temperate forest and grassland
… and the other a prairie and cropland on a Mollisol derived from loess over glacial till in Western Iowa. Tree ring data suggest that the forested site has been intact for about 70 years, although part of the site was used for grazing for a period. A monument marker at the prairie site …

Soil phosphatase activity: sources of variability and relationships with phosphorus fractions
… at co-located cropland and grassland on a Mollisol and at co-located tilled and no-till croplands on an Andisol. The second chapter tested hypothesized relationships of PME activity with P fractions using a dataset compiled from published and unpublished studies. The study evaluated the …

Soil quality in long-term corn and soybean rotations
Although soil quality is significant for crop productivity, input efficiency, and environmental stewardship, the effect of cropping systems on soil quality has not been examined very thoroughly for most cropping systems in the Midwest. Thus the advantages and disadvantages associated with standard …
