1. Enhanced Efficiency Nitrogen Fertilizer: Coated UreaNitrogen (N) is the most common fertilizer. However, a large percentage is lost to the environment—resulting in pollution and depletion of natural resources—representing economic losses. Enhanced Efficiency Fertilizers (EEF) help mitigate these problems by reducing the time N is in forms most susceptible to loss, increasing uptake efficiency and, often, yield and/or crop quality. One example of N EEF are coated urea fertilizers, such as polymer coated urea (PCU). Research studies show... S. Fahning, B.G. Hopkins |
2. Nitrogen Response of 2-Row Barley in North DakotaIn about 2019, the major malting barley buyers moved from 6-row barley cultivars to 2-row barley cultivars. The N response of 6-row barley was well-established, however, little local data regarding 2-row cultivar N response was available. A 2-year study was conducted in North Dakota on two sites, using two cultivars at each site. Rates of N from 0 to 160 pounds N per acre were imposed on each cultivar. One site was in a long-term (30+ years) no-till system, while the other site was in a transitional... A. Wick, D. Franzen, B. Goettl |
3. Relationship Between Soil Health and Nutrient Availability in Semi-arid Cotton ProductionThe use of conservation management practices, like cover crops and no-tillage, is common in semi-arid cropping systems to reduce wind erosion. However, the use of these practices can also reduce cotton lint yield. The purpose of this study was to determine the impact of nitrogen (N) management in conservation cropping systems to increase cotton lint yield. Two experiments were conducted at the Agricultural Complex for Advanced Research and Extension Systems in Lamesa, TX, USA. The first experiment... J. Burke, K. Lewis, J. Foster |
4. Double Cropping Wheat System Effects on Soil Extracellular Enzyme Activity Related to Nitrogen and Phosphorous Cycling Across TexasConventional management of agricultural systems can threaten soil health by contributing to soil erosion, soil carbon loss, and inefficient water use in crop production. Cover crops and conservation tillage have been reported to improve soil health, but the additional planting and maintenance comes at an additional cost. Double-cropping systems have the potential to mitigate that cost by providing producers a secondary crop with an additional source of income while providing soil health benefits.... H. Valencia, K. Lewis, J. Foster |
5. Recent 2-Row Malting Barley Nitrogen Rate Revision for North DakotaAs the demand of two-row malting barley (Hordeum vulgare L.) increases, having sound nitrogen (N) recommendations is increasingly necessary. Not only does N play a role in grain yield, but it may also significantly impact grain malting characteristics including protein, plump, and test weight. To determine the impacts N rate and N availability have on two-row malting barley, two experimental sites were established in both Spring 2020 and 2021. The experiments were organized as a randomized... D. Franzen, B. Goettl |
