Estimation of Biophysical Variables

Operational Implementation Plan

For specific fields: LAI (Sunscan), crop type, crop cover, wet biomass, phenology, and plant density.

Biophysical Variables
  • Vegetation Indices (NDVI, EVI, SAVI, etc.)
  • LAI (Leaf Area Index)
  • Biomass

Forecasting Agricultural Variables

Operational Implementation Plan

In the DEMMIN test site there are 45 autonomous operating automated stationary environmental measurement stations with soil moisture probes (up to 1m depth,10cm resolution) and 65 soil moisture gauging stations below agricultural used fields (depths 50cm, 70cm). The measuring interval is 15 minutes.

Agricultural Variables (large scale)
  • Soil Moisture

Site Description

Landscape TopographyThe altitudinal range within the test site is around 50 m with some slopes of considerable gradients (12 °) along theTollense River in the southeastern part of the test site.
Typical Field SizeThe test site is an intensively used agricultural ecosystem dominated by extensive fields (80 ha) where mainly wheat and maize are cultivated.
Climatic ZoneTropics, warm
