Irrigation Compatibility
Time-frame: 1999 to present
County location: Emmons, McKenzie, Mercer, and Oliver Counties in North Dakota
Field techniques: Soil observation and sampling for texture on a grid pattern using standard methods and guidelines outlined by the Natural Resources Conservation Service (NRCS) Soil Survey Staff.
Project types: Irrigation potential reconnaissance, Irrigation compatibility after disturbance
Project sizes: Three (80) to 95,000 acres
Equipment/tools/instruments: Tiling spade, bucket auger, Daubenmire quadrat, registered rectified aerial photography, laptop computer loaded with GIS software and outfitted with a GPS receiver
Laboratory data: Particle size analysis; and organic matter content
Databases accessed: NRCS County Soil Surveys; North Dakota State University (NDSU) Soils Dept. County General Soils Map; ND Dept. of Transportation GIS database
Data analyses and interpretation: Soil characteristics that influence water and soluble salt movement through soils were analyzed. A reconnaissance review of the large areas entailed determining these characteristics using soil survey information. The North Dakota Irrigation Guide was then used to rate each soil mapping unit for irrigation potential. GIS was used to compile and display an irrigation compatibility map for the project areas. The smaller field investigation compared textural and organic matter data to soil characteristics delineated in the NRCS county soil survey prior to disturbance. GIS was used to analyze and display the spatial distribution of particle size and organic matter content
Salinity and Sodicity Research

County location: Divide and Foster Counties in North Dakota
Field techniques: Soil delineation at a scale of 1:4,800 (Order 1) using standard methods and guidelines outlined by the Natural Resources Conservation Service (NRCS) Soil Survey Staff. Grid and linear transects were used for soil observation and sampling. Plant community analysis using transect and quadrat methods
Project types: Saline seep hill slope study; sodic soil hill slope study
Project sizes: five (5) acres
Equipment/tools/instruments: Hydraulic soil probe, rod and transit, refraction seismograph, resistivity probe, water level recorder, rain gauge, meteorograph, neutron moisture meter
Laboratory data: Particle size analysis; well water, 1:1 extract, and saturated paste extract pH, EC, major cations and anions, and SAR. Plant weight analysis
Databases accessed: NRCS County Soil Surveys; ND Geological Survey and Water Commission County Geology and Groundwater Resources Report
Data analyses and interpretation: Standard and geostatistical analyses were applied to chemical and physical data collected at research sites to determine the relationship between soil properties and water-salt movement.
Professional team: Soil scientist and plant specialist
Septic System Suitability
Time-frame: 1998 to present

Data analyses and interpretation: Soil texture and internal drainage were evaluated for water percolation. GIS was used to analyze and display the spatial distribution of soil properties.
Soil and Water Vulnerability Analysis
Time-frame: 1993 to present
County location: Statewide in North Dakota
Field techniques: Soil observations were compared in real time with GIS data layers displayed on a laptop computer outfitted with a GPS receiver and carried to the field
Project types: County maps for groundwater vulnerability to pesticides http://www.ageng.ndsu.nodak.edu/pest/; Water resource vulnerability to pesticides for Integrated Pest Management; Water resource vulnerability to nutrients related to animal production facilities; Water resources vulnerability to nutrients related to conservation management
