      Evaluating the Role of Water Availability in Determining the Yield–Plant Population Density Relationship
      Core Ideas
      • The effect of plant population density on soil water availability is analyzed.
      • Horizontally uniform irrigation and maximum possible suction applied by plant roots are assumed.
      • The analysis requires knowledge of only the radius of the active root zone and the soil capillary length.
      • The water-competition factor is proportional to the product of the root system radius and soil capillary length.

      Mineralogical Transformations and Soil Development in Shale across a Latitudinal Climosequence
      Core Ideas
      • Detailed characterization of the morphology, geochemistry, and mineralogy of shale-derived soils across a climosequence documents enhanced weathering and soil development with increasingly warm and wet climates.
      • The deepest weathering reaction observed in the regolith across the shale climosequence was plagioclase feldspar dissolution, which may be the profile initiating reaction that begins the transformation of shale bedrock to weathered regolith.
      • The abundance of chlorite and its transformation to vermiculite and HIV are more likely controlling regolith thickness in these soils.

      • The impact of oilseeds on soil properties that govern wind erosion is largely unknown.
      • Oilseeds resulted in less residue biomass and cover than conventional wheat rotations.
      • Oilseed crop residue must be carefully managed to minimize wind erosion.

      Iron and Sulfur Porewater and Surface Water Biogeochemical Interactions in Subtropical Peatlands
      Core Ideas
      • Surface water sulfate has been implicated in influencing Hg cycling and methylation, this relationship is tenuous at best therefore other variables and biogeochemical cycles could be involved with Hg methylation dynamics.
      • While thought of as a minor biogeochemical constituent, Fe is involved several biogeochemical interactions including the regulation of surface water sulfate concentrations by producing iron minerals.
      • The results of this study suggest that dissolved organic C supply has the ability to regulate dissimilatory sulfate reduction, rather than sulfate supply within the Everglades marsh.
