Expanding Your Horizons at NDSU

Expanding Your Horizons is a nationwide organization that holds regional conferences for young women in grades 7-9 to encourage and develop their career interests in science, technology, engineering, and math (STEM) in an effort to overcome a history of limited participation by women in these career fields. As shown in above picture, students Anne Gatzke and Hannah Bye demonstrated irrigation and drainage to 9 middle and high school girls in our research lab during the event organized by NDSU on April 9, 2016.

Installation of Soil Moisture Sensors

The SDI-12 Hydra Probe II soil moisture sensors have been installed in Burkland Farms, Grand Forks County on November 9, 2015. The sensing system measures soil moisture, electrical conductivity and temperature at surface (0-5 inches) and below at seven depths (5, 15, 30, 45, 60, 75, 90 inches). The CR1000 datalogger of Campbell Scientific, Inc. with a 12V battery and a 20W solar panel reads signals and stores data.

Undergraduate Research Presentation at NDSU Explore

Anne Gatzke of our group is presenting her research at NDSU Explore, an annual event celebrating the scholarly accomplishments of NDSU undergraduate students on November 3, 2015. The tittle of her poster is "Impact of Various Mulches on Sweet Corn Germination, Plant Growth, and Yield".

Ditch Water Quality and Flow Survey

Dr. Xinhua Jia and her research group are doing the water quality and flow survey along the field ditch. The water quality parameters,  such as nitrate, phosphate, turbidity, dissolved oxygen, electrical conductivity, pH and temperature are measured and the water flow is estimated. Water samples are also collected for further lab analysis.

Measuring Surface Runoff in the Field

A Greyline Stingray portable level-velocity logger is used to measure the real-time water flow discharging from the culvert to the ditch. 
PhD. student Debjit Roy and freshman Connor Yaggie are launching the program of the water level logger. The Onset HOBO water level logger was set up next to the culvert on the field side.

Eddy Covariance System in the Field

Eddy covariance system is also set up along the soil moisture sensors in the same field. It provides data to estimate the evapotranspiration (ET). Dr. Xinhua Jia is showing ABEN freshman Connor Yaggie how to download the data from the Campbell Scientific CR3000 datalogger after installation of the system.
