TRIAL BEFORE SCALE
What the grower should measure.
Use the actual pot, trough or bag in the trial. Keep the filled volume, settling, watering changes and drain observations with the plant and crop-stage record. Agree how the planned period of use will be assessed; initial hydration alone is not evidence for several seasons.
Irrigation inputs
Frequency, shot size, source-water EC and feed strategy.
Root-zone response
Drain or run-off, root-zone EC, wetting, rewetting and dry-back.
Crop response
Establishment, uniformity, root health, plant balance and marketable yield.
Commercial fit
Planting dates, filled units per order, packing identification, container handling and receiving-site access.
