1. Long-Term Effects of a Large Composted Cattle Manure Application Followed by Cover Crops to Organic Dryland Winter Wheat Cropping SystemsOrganic agriculture in semi-arid environments can face several challenges in order to produce a successful crop. These include nitrogen and phosphorus deficiencies, moisture limitations, and high weed competition. Organic winter wheat (Triticum aestivum, L.)-fallow systems can be amended with composted cattle manure and with green manure from cover crops grown in the fallow phase to help increase wheat yields and quality. Cattle manure can improve soil health with the... C. Helseth, U. Norton |
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. Cover Crops in Certified Organic, Specialty Crop Food ProductionThere is a growing interest in certified organic, specialty crop food production. With a larger population demanding organic products and organic products offering a higher premium for the producer, farmers are exploring the transition to organic farming. Organic producers in southeastern Wyoming face multiple challenges in environments with high elevation, low precipitation, and have a short growing season. These challenges include management of persistent weeds, maintaining biodiversity, and... E. Moore, U. Norton |
4. 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 |
