Purpose:

The potential of biomass from agricultural land is not a constant value, but rather a dynamic one that is influenced by changes in many factors and characteristics. By monitoring the productivity of their plants, farmers can manage the production process. Identifying which parts of their cover cropped fields are performing more or less is crucial information for determining how much nitrogen to apply for the next cash crop. Also, knowing when and what to harvest can result in higher yields, as every day matters. Therefore, having a biomass calculator is essential in the decision support tool to aid the farmers in their work.

...

1. On the home page, ask the user if they have sampled biomass or if they would like to use satellite data to estimate biomass

   1. If they have sampled biomass, the flow is exactly as it currently is in the tool

   2. If the want to use satellite data to estimate biomass, the flow will be what’s shown below

2. Location tab

   1. Stay the same as the current develop branch, name field, select polygon.

   2. Remove the calculate biomass button from

      1. Biomass will be displayed at the end

3. Soil tab

   1. Add text saying

      1. This model will use the SSURGO soil data from your field to estimate cover crop decompostition

      2. No sliders to adjust soil data

   2. Eventually fetch SSURGO data for each pixel

      1. Display the range of Organic Matter(~om_r), Bulk Density (~db_thirdbar), Soil Inorganic N (~InorganicN)

4. Cover crop tab

   1. Add cover crop planting date

   2. Remove dry, fresh biomass, water content → will always be 80% or so

   3. Select cover crop species, planting date with year, termination date with year (add in some error handling, could be in the future) at this point?

      1. Two scenarios.

         1. Past mode → running from planting until a date in the past or today.

         2. Past + future mode → running from planting to a date in the future.

      2. If the date is in the future, get the biomass today using the HLS API using real weather, and then use the 5 year average route from the NCALC API with the current biomass (from today) to make a future prediction.

   4. Quality values come from lookup table, should not be editable from sliders (page 2 of cover crops goes away) (this will need the lookup table to exist, ignore for now)

5. Cash crop tab

   1. No changes

6. Output

   1. Two tabs

      1. One is just like the current output (this will need the lookup table to exist, ignore for now)

         1. Calculate the average biomass for all pixels and then use that to generate the existing graphs.

      2. The other has the geospatial biomass, and nitrogen variability at the point of termination

         1. Display a map of biomass for the selected polygon

         2. As another layer display nitrogen released at a specific date (this will need the lookup table to exist, ignore for now)

         3. Have a text box to select a new date to run the model on

         4. Have an export button to feed to a tractor for spatial nitrogen application recommendation (this will need the lookup table to exist, ignore for now)

Aside note → only use centroid for weather data
