The LTAR Network

The Long-Term Agroecosystem Research (LTAR) Network is a new network developing national strategies for the sustainable intensification of agricultural production.

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

The LTAR 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

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


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.

Nice article on the @NutNetGlobal site at Shortgrass Steppe @USLTAR run by #CiniBrown #JuliaKlein & #DanaBlumenthal for over a decade @CSUAgSci @USDA_ARS @USLTAR @USLTER #Ecosystem #Ecology #Nitrogen #Phosphorus #Herbivores #GlobalChange #Grasslands

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.

The #USLTAR network is composed of 18 locations distributed across the contiguous United States working together to address national and local agricultural priorities and advance the sustainable intensification of U.S. agriculture. Learn more:

Rainfall events in the SW US becoming more intense as predicted @USLTAR and @USDA_ARS. @USDAClimateHubs

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
