The Use of Sediment Removal to Reduce Phosphorus Levels in Wetland Soils and the Distribution of Plant-Available Phosphorus in Wetland Soils and its Potential Use as a Metric in Wetland Assessment Methods
(North Dakota State University, 2014)
Plant-available phosphorus (P) in wetland soils and its relationship with wetland communities and condition is somewhat unknown in the Prairie Pothole Region (PPR) in North America. Research objectives were to determine ...
Soil Salinity and Sodicity Impacts on Soil Shrinkage, Water Movement and Retention
(North Dakota State University, 2015)
Saline, sodic, and saline-sodic ground waters are problematic throughout the Northern Great Plains and Red River Valley. High sodium adsorption ratio (SAR) and low electrical conductivity (EC) of soil solution and irrigation ...
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 ...
Phosphorus Dynamics and Crop Productivity in Bakken Crude-Oil Remediated Soils
(North Dakota State University, 2018)
Thermal desorption (TD), a remediation method used to remove hydrocarbons from contaminated soils, may cause changes in soil properties that threaten soil function and plant productivity. The goal of this research is to ...
Predicting Soil Health and Function of the Barnes Catena Using Evapotranspiration, Vegetative, Geologic, and Terrain Attributes in the Eastern Glaciated Plains of North Dakota
(North Dakota State University, 2018)
The benchmark Barnes soil series is an extensive northern Great Plains upland Hapludoll that is vital to the region. Accelerated erosion has degraded Barnes agricultural soil quality, but with unknown extent or severity. ...
Screening Hard Red Spring Wheat Cultivars for Reduced Phosphorus Fertilizer Requirement
(North Dakota State University, 2017)
Phosphorus (P) is a common macronutrient required for hard red spring (HRS) wheat (Triticum aestivum L.) growth and yield expression, and is a significant expense for farmers. The objective of this study was to screen 89 ...
