The LTAR Network

We are a growing research network focused on developing national strategies for improved agricultural production. Our goal is to improve environmental quality and the well-being of farming communities while achieving increased agricultural production.

The LTAR Network is a partnership among 18 premier long-term research sites across the United States.

The Network has a multifaceted focus on satisfying increasing demand for agricultural commodities, protecting the quality of the environment, and enhancing the quality of life in rural areas and the Nation as a whole

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.
