The kinematic runoff and erosion model KINEROS is an event oriented, physically based model describing the processes of interception, infiltration, surface runoff and erosion from small agricultural and urban watersheds. The watershed is represented by a cascade of planes and channels; the partial differential equations describing overland flow, channel flow, erosion and sediment transport are solved by finite difference techniques. The spatial variation of rainfall, infiltration, runoff, and erosion parameters can be accomodated. KINEROS may be used to determine the effects of various artificial features such as urban developments, small detention reservoirs, or lined channels on flood hydrographs and sediment yield.
Data from: Development of PLEAD: a database containing event-based runoff P loadings from agricultural fields
The P Loss in runoff Events from Agricultural fields Database (PLEAD) is a compilation of event-based, field-scale dissolved and/or total P loss runoff loadings from agricultural fields collected at various research sites located in the US Heartland and Southern US. The database also includes runoff…
Product system boundaries (cow-calf-finisher, CCF) include all material and energy flows associated with crop production and live cattle operations. Cattle inventory flows include the cow-calf operation and end with market weight finisher cattle and culls resulting from one full year of operation. The total live weight produced in one year is 2914841.44 kg and is comprised of the following animals: Finished cattle: 3724 (581 kg/finisher), Culled cows: 1156 (636 kg/cow), Culled bulls: 58 (908 kg/cow). These data were developed using Integrated Farm System Model and are intended to represent the MARC cattle operation in Nebraska in 2011. The data were a product of a project funded by the National Cattleman's Beef Association.
Data from: Selenium geochemistry in reclaimed phosphate mine soils and its relationship with plant bioavailability
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.
National Extension Web-mapping Tool (or NEWT), is the key in efforts to make spatial data available within the Cooperative Extension System. NEWT requires no GIS experience to use. NEWT provides access to relevant spatial data at a variety of scales (national, state, county) in useful formats (maps, tables, graphs),
Agricultural Land Management Alternative with Numerical Assessment Criteria (ALMANAC) Simulation Model
The Agricultural Land Management Alternative with Numerical Assessment Criteria (ALMANAC) model simulates crop growth, competition, light interception by leaves, biomass accumulation, partitioning of biomass into grain, water use, nutrient uptake, and growth constraints such as water, temperature, and nutrient stress. Plant development is temperature driven, with duration of growth stages dependent on degree days. Each plant species has a defined base temperature and optimum temperature.
The National Rabies Management Program conducts ORV operations in many US states. State summaries, maps, and statistics for oral rabies vaccine distribution can be accessed through this database.
GRIN-Global (GG) is a database application that enables genebanks to store and manage information associated with plant genetic resources (germplasm) and deliver that information globally. The GRIN-Global project's mission is to provide a scalable version of the Germplasm Resource Information Network (GRIN) suitable for use by any interested genebank in the world.
The Organic INTEGRITY Database is a certified organic operations database that contains up-to-date and accurate information about operations that may and may not sell as organic, deterring fraud, increases supply chain transparency for buyers and sellers, and promotes market visibility for organic operations.
