Soil Moisture Prediction Using Meteorological Data, Satellite Imagery, and Machine Learning in the Red River Valley of the North
(North Dakota State University, 2021)
Weather stations provide key information related to soil moisture and have been used by farmers to decide various field operations. We first evaluated the discrepancies in soil moisture between a weather stations and nearby ...
Can Soil Microbial Activity Be Improved With the Use of Amendments?
(North Dakota State University, 2020)
Low microbial activity and associated nutrient cycling are concerns in agricultural problem soils. The objectives of this study were to investigate microbial response on problem soils to amendments, drying-wetting cycles, ...
The Effect of Salinity on Soil Microbial Community Structure
(North Dakota State University, 2020)
Soil salinity is a widespread problem that affects crop productivity. We expect that saline soils also have altered microbial community structure, soil food webs and related soil properties. To test this, we sampled field ...
The Biogeochemistry of Soil at Depth Within the Wetland Landscape of the Prairie Pothole Region
(North Dakota State University, 2021)
The impact of agricultural practices on wetland ecosystems in the Prairie Pothole Region (PPR) has long been recognized but little is understood about impacts on the biogeochemistry of the wetlands at depth. Understanding ...
Seeding Time and Interseeded Cover Crop Species Influence Sugarbeet Yield and Quality
(North Dakota State University, 2020)
Field experiments were conducted to evaluate cover crop interseeding time and species effect on sugarbeet production during 2018 and 2019 growing seasons. Cover crops were first interseeded in June and second interseeding ...
Understanding the Role of Soils in Decision Making: Urban Agriculture and Septic Systems
(North Dakota State University, 2022)
Rural and urban dwellers frequently face decisions relating to human health. Among these are issues pertaining to water quality, and the availability of safe and nutritious food. Rural septic systems treat household ...
Soil Biological Functioning and Recovery in Soils Disturbed From Bakken Oil and Gas Activities
(North Dakota State University, 2022)
Oil and gas activity-related soil disturbances can alter soil properties and reduce microbial function, which is crucial for nutrient cycling and proper soil function. The goal of this research was to investigate effects ...
Evaluating Ornamental Grasses for the Challenging Rain Garden Environment
(North Dakota State University, 2022)
Four experiments were conducted to determine the growth and survival of seven species of perennial ornamental grasses, tufted hairgrass [Deschampsia cespitosa (L.) P. Beauv.], switchgrass (Panicum virgatum L.), big bluestem ...
Calcium Acetate: An Alternative to Gypsum for Brine Impacted Soils
(North Dakota State University, 2022)
With North Dakota being ranked as a leading producer of oil and natural gas in the United States, the possibility of accidental produced water (aka “brine” or “salt water”) spills is a continuous concern. Brine water poses ...
Proposed Nonparametric Tests for the Simple Tree Alternative for Location and Scale Testing in a Mixed Design
(North Dakota State University, 2022)
Six nonparametric tests are proposed for the mixed design consisting of a randomized complete block design (RCBD) and a completely randomized design (CRD). The proposed tests are designed to test for differences in location ...
