Soil health assessment of the Sanborn Field long-term experimental study
… associations between soil organic carbon, total nitrogen, potentially mineralizable nitrogen, active carbon, microbial biomass, and water stable aggregates; while a strong negative linear correlation existed between each of these properties and bulk density. The second study was conducted to …

Developing near- and mid-infrared spectroscopy analysis methods for rapid assessment of soil quality in Illinois
… N), soil pH, particulate organic matter (POM), potentially mineralizable nitrogen (PMN), fluorescein diacetate (FDA) hydrolysis, soil nutrient abundance, and productivity proxy Normalized Difference Vegetation Index (NDVI), using the whole NIR or MIR spectra or reduced data sets comprised of …

Effect of rotation, organic inputs and tillage on crop performance and soil quality in conventional and low-input rotations in central Iowa
… basis, particulate organic carbon (POM-C) and potentially mineralizable nitrogen (PMN) were increased in both LEI rotations relative to a two year (2-yr) corn (Zea mays L.) -soybean (Glycine max L.) rotation. Biologically labile organic matter fractions were highly stratified in the 2-yr …

Effect of summer and winter rotations on selected soil properties and productivity of succeeding winter chickpea (Cicer arietinum L.)
… (AC), organic carbon (OC), (NH4+) ammonium and potentially mineralizable nitrogen (PMN). Crop phenology (days to 50% emergence, flowering, and podding) and crop growth (plant height, canopy cover, number of primary and secondary branches) were determined at various crop growth stages. Grain …

Multifunctional woody polycultures and their influence on soil organic carbon
… fractions (particulate organic matter [POM], and potentially mineralizable N [PMN]), inherent soil and landscape factors were quantified on samples collected using plot- and grid-based approaches to understand their influence on soil organic carbon (SOC) change. Baseline soil samples were …

Legacy effects of cover crop monocultures and mixtures on soil inorganic nitrogen, total phenolic content, and microbial communities on two organic farms in Illinois
… soil environments by influencing soil inorganic nitrogen (N) pools, total phenolic content through the release of secondary compounds, and by altering soil microbial communities. I analyzed soils collected during a two-year field study and aimed to determine how spring-sown cover crops (grass, …
