We are interested in the irrigation efficiency of micro-irrigators on small-plot organic crops grown in the Palouse Region of North Idaho and Eastern Washington. To facilitate our study, we incorporate apparent electrical conductivity, saturated hydraulic conductivity and water retention measurements with texture, volumetric water and irrigation flow monitoring. Ultimately, we hope to be able to provide future growers in the region with an estimate for irrigation prescription with methods to ensure efficient water use in the face of increasing groundwater scarcity.

I am researching the soil health benefits of intercropping in fields in southern Idaho under different watering regimes. To assess this, I am working with an experimental plot in Aberdeen which is split between traditional monocropping and intercropping practices with various pulses. For each of these treatments, I am assessing Carbon and Nitrogen content in the soil, microbial communities and abundance, nutrient transfer between roots via stable C and N isotopic analysis, and greenhouse gas flux from soil.

My research attempts to predict nutrient and contaminant levels in soil and wildfire ash based on hyperspectral reflectance. To determine the amount of phosphorus in a soil sample, or lead in wildfire ash, lab analysis is traditionally required. However, the same information could potentially be obtained based on the specific wavelengths of light that the samples reflect. I am using the Vis-NIR range (350-2500 nm), and if successful, my project findings could be applied to drone and/or satellite systems for remote sensing of environmental data.
