Ag Data Commons migration begins October 18, 2023

The Ag Data Commons is migrating to a new platform – an institutional portal on Figshare. Starting October 18 the current system will be available for search and download only. Submissions will resume after the launch of our portal on Figshare in November. Stay tuned for details!

Data from: Assessing pollen nutrient content: a unifying approach for the study of bee nutritional ecology

    Poor nutrition and landscape changes are regularly cited as key factors causing the decline of wild and managed bee populations. However, what constitutes “poor nutrition” for bees currently is inadequately defined. Bees collect and eat pollen: it is their only solid food source and it provides a broad suite of required macro- and micronutrients. Bees are also generalist foragers and thus the different pollen types they collect and eat can be highly nutritionally variable. Therefore, characterizing the multidimensional nutrient content of different pollen types is needed to fully understand pollen as a nutritional resource. Unfortunately, the use of different analytical approaches to assess pollen nutrient content has complicated between-studies comparisons and blurred our understanding of pollen nutrient content. This dataset includes the raw data generated from each of our analyses, including pollen disruption and nutrient assays. We used our collective data to propose a unifying approach for analyzing pollen nutrient content. This will help researchers better study and understand the nutritional ecology – including foraging behavior, nutrient regulation, and health – of bees and other pollen feeders.

    Feedstock Readiness Level (FSRL) evaluation: Thlaspi arvense (pennycress), hydroprocessing (HEFA), Midwest, Jun. 2021

      Feedstock readiness level evaluations are performed for a specific feedstock-conversion process combination and for a particular region. FSRL evaluations complement evaluations of Fuel Readiness Level (FRL) and environmental progress. The data from this evaluation, compiled in June 2021, assesses the maturity of *Thlaspi arvense* (pennycress), as a feedstock for the hydroprocessed esters and fatty acids (HEFA) conversion process in the United States Midwest region.

      Organic Beef Data from Integration of Crops and Livestock Project

        As the organic forage-finished beef industry continues to grow, it is important to understand factors that affect meat quality, characteristics of beef that influence human health, and sensory attributes of cooked beef. Research on alternative breeds and forage types that influence meat quality, FA and AA profiles, and sensory attributes in an organic forage-finished production system, as well as comparisons with alternative breeds is lacking. Data release is part of data management plan with USDA-NIFA funding. Data is from organic dairy beef steers collected at the West Central Research and Outreach Center, Morris, MN.
