1. Is Cover Crop Species Mixture and Diversity More Important at Building Soil Health than Shoot Biomass in a Semi-arid Region?Cover crop mixtures (CCMs) as partial fallow replacements have the potential to increase soil health, yet long-term studies on CCMs, especially in semi-arid environments are relatively rare. An eight-year study at two locations in semi-arid Montana sought to evaluate the effect of functional group (N fixer, tap roots, fibrous roots, brassicacae) and species richness (2, 6, and 8 species in a mix) on a range of biological, physical and chemical soil parameters. Although several soil health... P. Miller, C. Jones, C. Zabinski, K. D'agati, M. Housman, S. Tallman |
2. Optimizing Fertigation for High Value CropsIn irrigated farming systems, soluble and mobile fertilizers, such as sources of nitrogen, are often applied to crops through fertigation. Fertigation presents both opportunities and challenges. Potential opportunities include better synchronization of nutrient availability with crop demand through the growing season and potential energy savings. Challenges include the need for additional investment on infrastructure for nutrient injection into the irrigation conveyance and distribution system,... C.A. Sanchez, D. Zerihun |
