Crop scouting, one crop at a time
Each crop page is a reference for the person walking the field, covering what to check at each stage, what a count needs written next to it, where the crop is grown, and the PropelMapper calculator and form that go with it.
How much of each crop there is to walk

Hay and forage
Scouted by cutting instead of by leaf stage, with sweep counts that depend on plant height.
Other crop records
Vines, trees, houses and pastures
Not every crop is walked by growth stage. Vineyards and orchards are walked block by block, greenhouses bench by bench, pastures paddock by paddock. These pages cover that work.
Scouting in the field
A crop name starts the record. The field, growth stage, observation and follow-up make it useful when you return. The product examples on these pages show where those details go.
Follow a field through a whole season
Record every stage visit against the same field, and the season’s counts sit together when the grower asks what happened in July.
