FIELD MONITORING: A PRACTICAL APPROACH
Practical field monitoring combines three things: periodic imagery to see where fields differ or have changed, ground observation to establish why, and a durable record so both are still useful next season. The purpose is prioritisation — deciding which fields deserve your time this week.

MONITOR FOR PRIORITISATION, NOT COMPLETENESS
You cannot inspect everything at the right moment. The realistic aim is to know which fields have changed since you last looked, and to spend the walking time there. Anything that produces a long undifferentiated list of alerts fails this test.
A WORKABLE ROUTINE
- Review available imagery on a regular cadence and note fields with visible change or unusual variation.
- Walk the flagged fields and record what you actually found, with photographs and a date.
- Record the decision made, not only the observation.
- Note when imagery was unavailable, so gaps are known rather than assumed clear.
- Review at season end: which flags were meaningful, which were noise.
GROUND TRUTH IS PART OF THE RECORD
Ground observation is the highest-value data on the farm and the most easily lost. Capturing it against the field, with a date and a photograph, is what makes imagery interpretable later — and what turns a season of observations into a multi-year picture.
- Imagery coverage is intermittent; cloud and revisit intervals create real gaps.
- Change detection indicates that something differs, not what caused it.
- Alerts require judgement; no monitoring system can determine agronomic significance.
- Monitoring does not forecast yield or guarantee that problems are detected in time.
- AXARA Attention highlights fields where observed change may warrant a look, with the evidence shown.
- Persistent field records hold imagery observations and ground truth together.
- A change timeline per field shows what moved and when.
- Explicit gaps: where imagery was unavailable, the record says so.
How often should fields be monitored?
A regular review cadence through the growing season, tightened around key operations and weather events, works better than ad hoc checking.
Can monitoring catch problems early?
It can shorten the time between something changing and someone looking, subject to imagery availability. It cannot guarantee early detection.
What should I record on a field walk?
Date, location within the field, what you observed, a photograph, and the decision taken. The decision is the part most often lost.
Are alerts useful or just noise?
They are useful when each one shows its evidence and can be dismissed with a recorded reason. Alerts without evidence become noise quickly.
Does monitoring predict yield?
No. AXARA does not make yield predictions. Observation supports judgement about where to look and what to consider next.
