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

Hi #ESA2020! Want to learn about a 25y survey of #Soil organic C and N changes up to 1m depth in 10 agroecosystems (Annual, Perennials & Forest) Check out my talk and leave questions! Session COS182 https://eco.confex.com/eco/2020/meetingapp.cgi/Paper/86752

The virtual #ESA2020 begins August 3. The "Jornada pack" below includes 23 presentations by Jornada scientists or that involve the Jornada @USLTER and @USLTAR programs. (I hope all were uploaded...). https://eco.confex.com/eco/2020/meetingapp.cgi/Search/0?sort=Relevance&size=10&page=1&searchterm=Jornada&ModelType=Paper

Years of watershed research in the Southern Great Plains sums up the effect of crop-livestock management versus plain, untended tallgrass prairie on runoff and water quality. Read about the @JEnvironQual research: http://ow.ly/hWoj50AAbOW

'We have one Earth': Researchers Work To Boost Farm Production Without Causing More Harm https://www.wvik.org/post/we-have-one-earth-researchers-work-boost-farm-production-without-causing-more-harm #LTAR #KBSscience #LTER

Desertification is linked to wind erosion and dust. ARS created the @USLTAR to measure wind erosion and USDA’s Southwest Climate Hub offers details on how to control wind erosion and dust. https://go.usa.gov/xwm33

Awesome paper:#WaterBudgets across 18 Long-term Agrictural sites in USA. Highlights:
•Estimated uncertainty of all water budget components.
•Avf. water budget uncertainty, 25% of precipitation.
•Sites span a 0.4–1.1 evaporative fraction and a 0.8 – 4.8 aridity index @USLTAR https://twitter.com/Mark_Liebig/status/1261635695900348422

🥳 What a great #LTAR2020 annual network meeting!! Thank you to all @USLTAR researchers for visiting virtually our home at the @KelloggBioStn @michiganstateu Thank U @BBestelm 🥰 it was super fun to help coordinate this event. Till next year 💪👩🏻‍🔬👨🏻‍🔬🌾🐮📊 https://twitter.com/CaroCordovaEc/status/1255620229536899075/photo/1

Wrapping up Day 1 of our virtual #LTAR2020 annual meeting of the @USLTAR with ~ 240 attendees. Today we proposed a set of common indicators that reflect production, environment, and human condition in rangelands, pasturelands, and croplands across the US.

An excellent first day of presentations and discussions at the #LTAR2020 meeting! Kudos to the planning committee for pulling this off! @USLTAR
