Platte River - High Plains Aquifer (PR-HPA) Long-Term Agroecosystem Network (LTAR)

The Long-term Agroecosystem Research (LTAR) network, is an ARS-USDA effort that focuses on conducting research that addresses current and emerging issues in agriculture related to sustainability and profitability of agroecosystems in the face of climate change and population growth. There are 18 sites across the USA covering key agriculture production regions https://www.ars.usda.gov/natural-resources-and-sustainable-agricultural-systems/water-availability-and-watershed-management/docs/long-term-agroecosystem-research-ltar-network/. In Nebraska, a partnership between UNL led by ACSS faculty and ARD/USDA resulted in the establishment of the Platte River - High Plains Aquifer (PR-HPA) LTAR site in 2014. The site conducts research to sustain multiple ecosystem services focusing specifically on Nebraska’s main agronomic production agroecosystems that comprise of abundant corn, soybeans, managed grasslands and beef production. As part of this regional and national LTAR network, PR-HPA conducts long-term cross-site research assessments of new aspirational agricultural practices aimed at improving our understanding of decision making processes and outcomes across an array of agricultural systems applicable to local, regional, national and global scales.
