Current Research


The overall goal of this project is to demonstrate the economic and environmental benefits of a new type of deep subsoil treatment beneath a variety of cropping systems in Nebraska. This project will be coupled to existing grant-funded projects investigating leaching losses and transport rates of nitrate in Nebraska, and use new tools for characterizing nitrate management and demonstrate the effect of subsoil injections for managing nitrate losses. The results from these comparisons will be presented in an on-farm workshops and highlighted in several extension and outreach publications.

Novel Approaches for Controlling Nitrate Leaching and Protecting Nebraska Ground Water

PI: D. Snow; Co-PI’s: C. Ray and A. M. Schmidt.
Through this project, we intend to conduct replicated on-farm research on commercial crop operations throughout Nebraska, engage high school agriculture programs, and cooperate with agricultural communications experts to deliver educational programming to equip farmers and their advisors with knowledge and skills to identify relevant and optimal opportunities for recycling animal manures and cedar mulch as soil amendments.

From “Waste” to “Worth”: Livestock Manure and Cedar Mulch a “Win-Win” Combination for Nebraska’s Agriculture, Ecosystem Services and Econ

PI: A.M. Schmidt; Co-PI’s: R. Koelsch, L. Howard, J. Keshwani, G. Lesoing, A. Nygren, R. Saner, A. Timmerman, L. Thompson, and T. Whitney.

This project will support SARE’s sustainability goals of long-term profitability (better utilization of manure’s nutrient value), stewardship of natural resources (improved water and soil quality), and quality of life for rural communities (limit risk of manure’s negative qualities, such as odor). An existing multi-state working group will deliver a professional development program for those advising crop farmers intended to: build awareness of manure’s value; demonstrate benefits locally via on-farm research; and teach crop farmers to confidently identify "win-win" opportunities for manure use on cropland.

Long Pine Creek Woody Biomass BMP Evaluation

Through this project, we will study innovative technology for liquid manure wastewater treatment and nutrient recovery within the framework of a decision-making tool that allows technology selection based on region-specific needs to water recycling and food production. The tool will be built upon an economic and life cycle assessment model that guides technology selection based on soil chemistry, fertility, crops, livestock, desired treatment, water use, wastewater production and regulatory requirements.

Current Extension Projects

Funded by grants from We Support Agriculture, the Nebraska Environmental Trust, and North Central Region Sustainable Agriculture Research and Education (NC-SARE), this program is designed to support the environmental stewardship goals of livestock producers by promoting recycling of locally available livestock manure on crop fields prior to importation of inorganic fertilizers. On-farm research in Nebraska, Iowa and Minnesota is being used to demonstrate soil health, agronomic and economic impacts of manure as a soil amendment. Engagement of high school ag programs near all six Nebraska on-farm research sites is occurring through curriculum delivery and participation in research. Through partnerships with Nebraska agricultural commodity organizations, conservation and nutrient management agencies, and private industries, social media content developed and released by our project team on a monthly basis is being distributed via partners’ existing stakeholder communication processes. Content is focused on the value of manure as a fertilizer, manure and soil health, “recycling” manure, etc. and is available here.

Transforming Manure from “Waste” to “Worth” to Support Responsible Livestock Production

A nationwide outreach effort to improve knowledge among livestock producers and the non-agricultural public of the role each of us plays in the global health challenge of antimicrobial resistance. A team of university research and outreach faculty from the Northeastern, North Central, Western and Southern regions of the U.S. represent food safety, livestock production, veterinary medicine, engineering, and other relevant disciplines on this interdisciplinary effort to inspire action to preserve the efficacy of antibiotics for protecting human health. This effort has begun with developing a communications map that is being used to identify existing and needed resources on AMR, developing content to fill information gaps, and disseminating research-based information via social media, print, and popular press to build brand recognition for the program. As research funded by the integrated NIFA grants is completed, practice recommendations for livestock producers and consumers to mitigate human health risks from AMR will be disseminated.
