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.

My project aims to understand spatial variation of nitrate accumulation, uptake and leaching in agricultural systems. An overall goal of the project is to capture spatial patterns with hydrologic cropping models and identify practices that improve nitrogen use efficiencies and reduce instream loading.

Develop integrated model that encompasses outputs from an agent-based economic decision-making model of the Southern Idaho cropping system for IAMP crops and supply chains (e.g., production volumes, GHG emissions) into a system dynamics model that forecasts water supply and usage implications of adjusting cropping patterns toward enhanced adoption of CS practices. Some outputs from the agent-based model will be used as inputs for the system dynamics model through an input-output matrix, ultimately providing a useful insight for the research community and stakeholders to explore management alternatives in a changing climate.

I am looking at the effects of various intensities of wildfire on soils. I am doing this by burning multiple square meter plots using a ceramic heater and measuring how the soil responds. This information will be used to fortify a commonly used land management model known as the Water Erosion Prediction Project (WEPP) to help understand the effects of wildfires on forested watersheds.

My research interests are soil ecology, soil microbes and biogeochemistry. I am currently investigating the implications of agricultural antibiotic deposition on soil microbial communities and ecosystem processes. I am particularly intrigued in how soil microbial communities drive the formation of soil organic matter and long-term soil carbon storage.

My research has quantitatively established positive relationships between increased soil organic carbon (SOC) and soil available water capacity. However, these relationships do not adequately inform our understanding, particularly of how improved available water capacity impacts hydrological balances and crop water stress. This research addresses these knowledge gaps by using standardized crop water requirement and stress estimation procedures to determine SOC impacts on agrohydrological outcomes, including crop evapotranspiration, crop water stress, irrigation requirements and hydrological losses.

My research focuses on the application of dairy manure and chemical fertilizers to crop fields in southern Idaho. Through sample collection, producer surveys and data analysis, I will be determining the effect of these applications on soil health and soil fertility in southern Idaho. There is an additional goal of adding value to manure-based products as alternative fertilizer sources that provide adequate nutrient needs and improve soil quality.

Modeling water and nutrient transport in the Magic Valley region of south-central Idaho with a focus on assessing the long-term impacts of increased dairy agriculture. The SWAT model is being used to simulate irrigation schedules, canal withdrawals, land use changes and fertilizer application rates. The overall goal of the research is to assist in ensuring the long-term sustainability and growth of agriculture in the Magic Valley.

My research focus on the evaluation of phosphorus availability in response to biochar amendment. Studying nutrient release pattern of P in the soil system helps the farmers to take decision on the biochar application based on quality of biochar and soil properties. My research project emphasizes soil sustainability through the effective utilization of the available organic resources to meet the crop nutrient demand and to reduce the rate of fertilizer application.

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.

I'm working to understand how the practice of intercropping — growing two crops together on the same piece of land — influences soil health. My fieldwork takes place at the U of I Aberdeen Research and Extension Center, where we are growing nitrogen-fixing pulse crops together with barley. I use techniques such as stable isotope labeling to understand and trace nutrient uptake and allocation through the soil and plant ecosystem.
