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 ...
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 ...
Sugarbeet Yield and Quality Response to Nitrogen Fertilizer Rate and In-Season Prediction of Yield and Quality Using Active-Optical Sensor
(North Dakota State University, 2016)
Nitrogen (N) management is one of the important factors in sugarbeet production. Under-application of N-fertilizer results in lower root yield while over-application of N-fertilizer can result in decreased sugar concentration ...
Spring Wheat (Triticum aestivum L.) Response to Nitrogen (N) Loss Management and Sulfate-Based Soil Salinity
(North Dakota State University, 2016)
The first study was conducted during 2014 growing season at Glyndon, MN to evaluate the effectiveness of nitrification inhibitor or both urease and nitrification i.e. double inhibitors on reducing N losses in a rainfed ...
Chemical and Biological Characteristics of Thermally and Chemically Disturbed Soil in Northwestern North Dakota
(North Dakota State University, 2017)
Thermal desorption (TD) remediates hydrocarbon-contaminated soil by heating the soil (200 to 500 °C) to volatilize the hydrocarbons, effectively removing the contaminant from the soil. If the soil is then used for agricultural ...
Nitrogen and Phosphorus Recalibration for Sunflower in North Dakota
(North Dakota State University, 2016)
Sunflower is one of the most important annual crops grown for edible oil in the world and
is grown in North Dakota and the northern Great Plains more than any other region in the United
States. Sunflower production and ...
Evaluation of 1:5 Soil to Water Extract Electrical Conductivity Methods and Comparison to Electrical Conductivity of Saturated Paste Extract
(North Dakota State University, 2011)
Conducting a 1 :5 soil:water extract to measure electrical conductivity (EC) is an approach
to assess salinity and is the preferred method used in Australia. However, the influence of
salinity on plant growth is predominantly ...
Effects of Swine Slurry on Sorption of 17~-estradiol to Soil
(North Dakota State University, 2011)
178-estradiol (E2) is a potent endocrine disrupting compound that is found in swine
manure. Liquid swine manure or otherwise knov.n as swine slurry is commonly used as a
form of fertilizer in agricultural practices. ...
