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.
