      Semiquantitative Evaluation of Secondary Carbonates via Portable X-ray Fluorescence Spectrometry

      Secondary CaCO3 is commonly found in soils of arid and semiarid regions in variable states of development as Bk, Bkk, Bkkm, Ck, or, more rarely, Ak horizons. Historically, a qualitative scale featuring various stages of development has been applied when evaluating carbonate-laden soils. By contrast, this study used portable X-ray fluorescence spectrometry to determine the soil Ca concentration of 75 soil samples from four US states in relation to developmental stage, as determined independently by five pedologists from the USDA–NRCS Soil Survey Staff. Although they were experienced, the evaluators unanimously agreed on the carbonate development stage on only 22.6% of the samples while evaluating the samples ex situ. (continued)

      Core Ideas:
      • PXRF found differences in Ca content related to secondary carbonate development stage.
      • Strong correlation was found between intact aggregates and ground soil for Ca content.
      • Support vector classification successfully classified carbonate development stage.

      Impact of Three Types of Biochar on the Hydrological Properties of Eroded and Depositional Landscape Positions

      The addition of biochar to improve soil hydrological properties has been evaluated by many researchers. However, most studies have been conducted in controlled laboratories or greenhouses. This study was conducted in the field with the objective of evaluating the impact of biochar on the hydrological properties of soils at eroded and depositional landscape positions. Three plant-based biochar materials, produced from C-optimized gasification of corn stover (Zea mays L.) (CS), ponderosa pine (Pinus ponderosa Lawson and C. (continued)

      Core Ideas:
      • Biochar impacted soil physical properties.
      • Biochar improved soil water retention.
      • A lower rate of biochar was effective in improving water infiltration and water retention.
