1. Sheep Grazing Preference and Nutrient Cycling Implications Among Cover Crop SpeciesThe vast and interspersed livestock and crop industries of Texas lend opportunity for livestock integration to benefit regional agricultural systems. Texas leads sheep production in the U.S. and small ruminant integration in crop systems has become an appealing opportunity in recent years due to strong meat markets and generally poor commodity crop markets. Many winter cover crops are likely suitable forages, and challenges of nutrient immobilization could be (at least partially) mitigated by... R. Matschek, R. Noland, N. Nielson, J. Thorne, M.

2. Seeding Rate and Planting Configuration Affect the Interspecific Function of a Wheat-pea Cover CropCover crop species mixtures have potential to maximize overall biomass as well as net N contribution if temporary immobilization of available N by non-legume species can promote greater N fixation by legumes. The growth and ultimate function of legumes in cover crop species mixtures is often limited, however, by excessive competition with other species, particularly grasses, in the mix. The objective of this work is to identify optimum cool-season legume-grass cover... N. Nielsen, T. Hussain, R. Matschek, R. Noland, M. Mcculloch |
3. Defining Critical Tissue-Potassium Concentrations for Furrow Irrigated Corn ProductionPotassium (K) is a critical nutrient for adequate corn (Zea mays L.) production, and tissue testing is an essential tool to ensure adequate K nutrition. Despite the important role of K in plant physiological functions, there are no calibrated critical tissue-K concentrations (TKc) for furrow-irrigated corn in Arkansas. This study aimed to define critical TKc values to maximize corn grain yield across different growth stages. From 2022 to 2024, twelve single-site-year and four long-term... J. Silva, G. Drescher, T.
