1. 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 |
2. Soil Microbes Are Critical to Maintaining Soil Fertility in the Great PlainsSoil in the Great Plains is known to be susceptible to wind and water erosion due to moisture deficits throughout the region that limit soil organic matter (SOM) accumulation that helps form stable soil structure. Conservation management practices like reduced tillage are emphasized to maintain SOM that provides habitat for soil microbes to perform ecosystem services related to nutrient cycling and soil aggregation to increase resistance to erosion and maintain fertile topsoil. Soils under long-term... W. Roper, V. Acosta-martinez, J. Moore, M. Mikha, D.K. Manter, C.E. Stewart, R.M. Lehman, M.A. Liebig, V.L. Jin |
3. 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 |
