Who We Are
The LTAR Network is a growing group of researchers focused on finding solutions that maintain or increase agricultural productivity, environmental quality, and people well-being in spite of pressures such as climate change. Read more
Our Research Approach
The LTAR network combines strategic research projects with common measurements on multiple agroecosystems (croplands, rangelands, and pasturelands) and develops new technologies to address local and national challenges and opportunities.

ABOUT LTAR
The USDA Agricultural Research Service (ARS) Long-Term Agroecosystem Research network consists of 18 Federal and university agricultural research sites with an average of over 50 years of history. The goal of this research network is to ensure sustained crop and livestock production and ecosystem services from agroecosystems, and to forecast and verify the effects of environmental trends, public policies, and emerging technologies.
