The Influence of Soil Salinity Gradients on Soybean [Glycine Max (L.) Merr.] and Corn (Zea Mays L.) Growth
(North Dakota State University, 2015)
An estimated 2.3 million hectares are salt-affected in North Dakota (Brennan and Ulmer,
2010), a number increasing due to land management, climate, and crop choice. As a result, yield
reductions are noted for salt-sensitive ...
Evaluation of Soil Potassium Test to Improve Fertilizer Recommendations for Corn
(North Dakota State University, 2015)
A study was conducted at thirteen locations in North Dakota and Minnesota in 2013 and 2014 with the objectives of determining difference between the soil potassium (K) results based upon air-dried (KDry) and field-moist ...
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 ...
Evaluating Dynamic Soil Change in the Barnes Soil Series Across Eastern North Dakota
(North Dakota State University, 2015)
Quantifying long-term, global soil change is of the utmost importance as the human population continues growing and food security needs intensify. North Dakota presents a unique opportunity to study dynamic soil change ...
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 ...
