About Us


Tellus is a digital experience that features stories about the cutting-edge work of the Agricultural Research Service (ARS), the U.S. Department of Agriculture’s chief in-house scientific research agency.

With more than 2,000 scientists at 90-plus research laboratories across the United States and overseas, ARS works daily to discover real-world solutions to agricultural challenges affecting our nation and a growing world. Our unique capacity to conduct research that has an impact on the food we eat, the water we drink, and the air we breathe makes ARS one of the world’s premier scientific organizations.

Tellus, Latin for Earth, reflects the global reach of our efforts to feed a growing population while remaining good stewards of the land.

ARS research touches the lives of people everywhere – in ways both large and small. Through Tellus, we are excited to tell you, the consumer, stories about our revolutionary research and its impact on everyday life and on a growing world.

We hope you enjoy our site.
