Nitrogen Dynamics in Soils from the Red River Valley of the North
(North Dakota State University, 2015)The objectives of this study were to evaluate the effects of (i) N management on crop yield, N availability, and N losses from a silty clay having subsurface drainage, (ii) soil moisture and nitrification inhibitor nitrapyrin ... -
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 ... -
Sodic Soil Swelling and Dispersion and their Implications for Water Movement and Management
(North Dakota State University, 2014)North Dakota has over 1.9 million ha of sodium-affected soils, influencing water movement and crop production. This dissertation consists of four studies examining different aspects of sodic soils. The first study surveys ... -
Soil Function Following Remediation Using Ex Situ Thermal Desorption
(North Dakota State University, 2017)Soils perform many functions essential to human and ecosystem health, and contamination by organic compounds diminishes the ability of the soil to perform those functions. One method for remediating contaminated soils is ... -
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 ... -
Symbiotic Nitrogen Fixation in Dry Bean Cultivars
(North Dakota State University, 2018)Dry Beans (Phaseolus vulgaris L.), is the second-most important grain legume, and North Dakota has ranked first in dry bean production. The overarching research question of my project is whether we can increase the nitrogen ...
