SOURCE DATA

Phase 6 Source Data

Download data tables including information on load sources and agencies, BMPs, animals, geographic references and delivery factors. The Source Data includes the following data tables:

  • Load Source Definitions
  • BMP Definitions
  • Efficiency BMPs
  • Load Source Conversion BMPs
  • Load Reduction BMPs
  • Animal BMPs
  • BMP Units
  • BMP Load Source Group
  • Load Source Group Components
  • BMP Animal Group
  • Animal Group Components
  • Geographic References
  • Geographic Scale and Names
  • Agencies
  • Delivery Factors

Download data tables including the tables listed below. Note that actual crop nutrient applications vary depending on acres of the crop, application yield goal, nutrient management, and monthly timing, and type and amount of nutrients available. The tables provide the factors used to determine the nutrient application amounts that may be applied depending on the specific conditions in any scenario.

  • Double cropped crops
  • Crop and load source relationship
  • Plant and harvest dates
  • Developed land (turfgrass) nutrient pounds per yield
  • Agricultural crop nutrient pounds per yield
  • Crop nutrient application by month
  • Crop nutrient uptake, removal, and nitrogen fixation
  • Crop cover factor
  • Crop cover fraction
  • Sediment tons available to erode due to plowing, by crop type

Download data tables including the following tables:

  • Animal Time in Pasture
  • Manure pounds per animal and per animal unit
  • Manure nutrient concentrations
  • Manure nutrient volatilization

BMP Calculations

Understanding how BMPs are calculated will help the user maximize their load reductions. The following topics are addressed in the narrative document: BMP types, BMP groups and sequence of calculation, overlapping and mutually exclusive BMPs, calculation steps with example calculations, and tips for maximizing load reductions.
