Uruguay-Colonia, San Jose, Soriano

Overview

The project has 3 sites withi Uruguay, which are located in Colonia, Soriano and San Jose.

The project objectives are:

Crop Condition/Stress:

  • Estimate the impact of management and identification of management zones within a field

Soil Moisture:

  • Estimate soil water holding capacity and crop evapotranspiration.

Yield Prediction and Forecasting:

  • Estimate yield pre harvest through crop modeling, in a small area (less than100 ha).

All sites have a soybean-wheat crop sequence. In each of the sites we measured biophysical parameters every 15 days:

  • Crop biomass
  • Crop cover
  • Leaf area index
  • Fraction of intercepted radiation
  • Identification of phenological event
  • Identification of management practices

Plans for Next Growing Season:

The project is continuing with similar objectives.  The main change is greater emphasis in modelling with assimilation of a reduced number of scenes.  We would like to incorporate more sensors to increase the temporal sampling of the sites.
