National Resources Inventory
The 2017 National Resources Inventory (NRI) conducted by the U.S. Department of Agriculture's Natural Resources Conservation Service (NRCS) provides updated information on the status, condition, and trends of land, soil, water, and related resources on the Nation's non-Federal lands. Non-Federal lands include privately owned lands, tribal and trust lands, and lands controlled by State and local governments.
Data from: Data on four criteria for targeting the placement of conservation buffers in agricultural landscapes
This article describes the data used to derive the values of attributes including soil erodibility, hydrological sensitivity, wildlife habitat, and impervious surface rate, and a scheme to classify the values in multi-criteria analysis of conservation buffer placement in the Raritan River Basin in New Jersey, USA.
Data from: Effects of conifer treatments on soil nutrient availability and plant composition in sagebrush steppe
Conifer control in sagebrush steppe of the western United States causes various levels of site disturbance influencing vegetation recovery and resource availability. The data set presented in this article include growing season availability of soil micronutrients and levels of total soil carbon, organic matter, and N spanning a six year period following western juniper (*Juniperus occidentalis* spp. *occidentalis*) reduction by mechanical cutting and prescribed fire of western juniper woodlands in southeast Oregon. These data can be useful to further evaluate the impacts of conifer woodland reduction to soil resources in sagebrush steppe plant communities.
International Soil Carbon Network
The ISCN is a self-chartered, international, collaborative organization composed of scientists who recognize a need for and value in large-scale synthesis of soil carbon science.
GRACEnet Soil Biology Network
The GRACEnet Soil Biology mission is to produce the soil biology data, including methods of identifying and quantifying specific organisms and processes they govern, that are needed to evaluate impacts on agroecosystems and sustainable agricultural practices.
Data from: Underestimation of N2O emissions in a comparison of the DayCent, DNDC, and EPIC 1 models
Process-based models are increasingly used to study mass and energy fluxes from agro-ecosystems, including nitrous oxide (N2O) emissions from agricultural fields. This data set is the output of three process-based models – DayCent, DNDC, and EPIC – which were used to simulate fluxes of N2O from dairy farm soils. The individual models' output and the ensemble mean output were evaluated against field observations from two agricultural research stations in Arlington, WI and Marshfield, WI. These sites utilize cropping systems and nitrogen fertilizer management strategies common to Midwest dairy farms.
Soil - Plant - Atmosphere - Water Field & Pond Hydrology
SPAW is a daily hydrologic budget model for agricultural fields and ponds (wetlands, lagoons, ponds and reservoirs). Included are irrigation scheduling and soil nitrogen. Data input and results are graphical screens.
Microbial community structure is affected by cropping sequences and poultry litter under long-term no-tillage
Soil microorganisms play essential roles in soil organic matter dynamics and nutrient cycling in agroecosystems and have been used as soil quality indicators. The response of soil microbial communities to land management is complex and the long-term impacts of cropping systems on soil microbes is largely unknown. Therefore, changes in soil bacterial community composition were assessed in response to cropping sequences and bio-covers at long-term no-tillage sites.
