The Nutrient Tracking Tool was designed to be user friendly, with following main pages:
On the Projects page, users can create a project by enter the name and description of the project, open saved/example projects, or upload projects from local source.
On the Location page, the users delineate the field or fields in their project using the interactive map. Alternately, users may upload their own shape files.
On the Fields page, the users either create new fields or verify the fields drawn on the Location page. Clicking on the fields allows the user to further define the field characteristics in the soils and management pages.
On the Soils page, the users may verify or delete the soils returned by the SSURGO database for their field. Users are also asked to indicate the soil P content for the field.
On the Weather page, the users select the source of weather information, as well as the length of simulation.
On the Management page, users create and name one or more management scenarios for the field. Each management scenario must be further defined on the Operations and Conservation Practices sub-project pages. Once the management scenario(s) has been defined, users may also simulate the scenarios by selecting the box next to the scenario name and clicking “simulate selected scenario”.
On the Operation page, users create the crop schedule and define management for the given field management scenario.
On the Conservation Practices page, users indicate the conservation practices that are in place on the field for the given field management scenario.
On the Results page, users can view and compare results of up to three management scenarios for a given field in tabular or graphical presentations. In addition, a PDF-formatted report for the project and results summary will be available for upload.
On the Field Routing page, users are able to create and name field routing scenarios. This also can be used for simulating for different scenario management in multiple fields or at subbasins within a watershed. A routing scenario will route runoff, sediment, and nutrients from one field to the next (within a subbasin and from a subbasin to the next if used for a watershed) in the specified order. For each routing scenarios users will need to list the field-scenario order.
