We have a new @USDA_NIFA-funded project to understand the socioeconomic and environmental trade-offs of heritage #cattle genetics, precision ranching, and range finishing in the Southwest. @nmsu @TheJornada @USDA_ARS @USLTAR

1) NOW OFFICIALLY RELEASED!

We are thrilled to announce that @PhenoCam Dataset v2 with nearly 1800 site-years of #phonology data from around the globe is now published on @ORNLDAAC.

THANKS to my 115 coauthors and many collaborators who made it happen.

Check out this @NSF story on research out of the @KBSLTER! Phil Robertson and co-authors discovered a new mechanism for determining how carbon is stored in soils, which could improve the climate resilience of crop systems & reduce their carbon footprints. https://t.co/fqnoSKK9Nz

Drought was the leading cause of crop loss from 2001-2016, resulting in $38b in insurance payments to farmers. Our latest paper analyzes weather+climate-driven loss events by mining federal crop insurance data. @Emile_H_Elias @TheJornada 1/n

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.
