AgriYieldz: The Wheat Crop Production Estimator

AgriYieldz provides information about the historical yield potential of a paddock in the last 30 years. It assumes the paddock was sown to wheat, every year. It assumes the wheat crop did not suffer from a lack of nitrogen, and was not penalised by weeds, disease or frost.

AgriYieldz generates a wheat yield for every paddock in Australia. It assumes Wheat was grown every year, for the last 30 years, and using the APSIM crop model, assumes the crop was grown with unlimited nitrogen, and was free from weeds, disease or frost. wheat yields are calculated using soil types from the ASRIS national soil grid of Australia. Historical climate data is provided by the Bureau of Meteorology. For a given field, the data generated, allows people to estimate:

  1. The long term average wheat yield potential.
  2. The variation in wheat yield potential, and the range of yield potentials for the last 30 years.
  3. The short term trajectory in wheat yield potential for the last 30 years.
  4. The data is provided as a vector, with an estimated yield for each of the last 30 years.

It is possible to compare the theoretical yield potential of multiple paddocks, when information is extracted for multiple paddocks. The variability in production between paddocks or regions can also be evaluated.

The dataset is a set of point locations, with dimensions {lat, lon, year}. Each location has the variables:

  • Wheat yield (float)
  • Biomass (float)
  • Soil water at Harvest (float)
  • Soil water at Sowing (float)
  • Plant available Water Capacity (float)
  • In Crop Rainfall (float)
  • SILO Station Number (integer)
  • ePaddocks ID (integer)
