Corn Response to Sulfur Fertilizer in the Red River Valley
(North Dakota State University, 2018)
A study was conducted at ten locations in North Dakota and Minnesota in 2016 and 2017 to evaluate corn response to different sulfur (S) application rates and to determine the relationship between corn yield and plant tests. ...
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 ...
Recalibration of Soil Potassium Test for Corn in North Dakota
(North Dakota State University, 2017)
Corn (Zea mays L.) production has greatly increased in North Dakota since the 1990s; yet, potassium (K) fertilizer recommendations for corn in North Dakota still date from the late 1970s and early 1980s when corn grain ...
Superabsorbent Polymer Effects on Soil Physical Properties and Use as a Compaction Alleviation Amendment in Surface Coal Mine Reclamation
(North Dakota State University, 2019)
Surface coal mine reclamation is challenged by alterations in soil characteristics, compaction being the most plant-yield reducing. Superabsorbent polymers (SAPs) ability to retain large volumes of water gives them the ...
Impacts of Kentucky Bluegrass and Patch-Burn Grazing Management on Soil Properties in the Northern Great Plains
(North Dakota State University, 2019)
Kentucky bluegrass (Poa pratensis L.; hereafter referred to as bluegrass) has rapidly invaded the northern Great Plains over the past three decades, leading to declines in native plant diversity. A knowledge gap exists ...
Can We Increase Crop Yield Adopting Tile Drainage in Fargo Clay Soil?
(North Dakota State University, 2018)
Subsurface drainage has recently become common for agriculturally productive soils and key to maintain and improve crop production in poorly drained, frigid clay soils. The first study was conducted for four years (2014-17) ...
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 ...
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 ...
Fertilizer Management Strategies of Soybean (Glycine Max, L. Merrill) in Northcentral and Northwestern North Dakota
(North Dakota State University, 2019)
Soybean (Glycine max L. Merrill) is a new cash crop for north central and northwestern North Dakota producers. Soils and climate in these new soybean areas differ from those regions where the current fertilizer recommendations ...
Advancing Soil Health: Linking Belowground Microbial Processes to Aboveground Land Management
(North Dakota State University, 2016)
Advancing soil health lies at the intersection of belowground microbial processes and aboveground land management. However, linking microbial processes to land use is difficult. Understanding the response of soil microbes ...
