Field level surveys
This sub-section focuses on the data that is collected at the level of the so-called farm management unit (FMU). FMU is an area with the same crop (combination) on which the same management strategies (e.g. weeding, fertilizer application, irrigation) are applied.
Four main categories of data to be collected are distinguished. These are:
- FMU characteristics,
- crop development information,
- farm management practices and
- biophysical characteristics
