Onion Field — Formation Level
Define the finished purpose, reference levels, underlying material condition and the evidence required by the receiving operation. Geometry alone does not establish structural or agronomic performance.
This reference assembles relevant extracts from the guide library. It is general project planning, not a local project report, verified specification or translated technical publication.
Onion Field Preparation
Onion-field preparation requires the field surface and final bed geometry to be treated as separate tasks. Correcting broad ponding before bed formation can prevent uneven conditions across the planting area.
Before moving material
Confirm bed layout, irrigation and the source of low spots.
Receiving operation and checks
Complete bed formation and crop-specific planting preparation. Inspect bed-end flow paths and retained soil depth.
No crop response or yield benefit is guaranteed by grading alone.

Uneven turf formation may arise beneath the growing layer or within it. Repeatedly topdressing the visible depression may leave the formation issue unresolved.
Before moving material
Locate the uneven area and identify the turf system's layer arrangement.
Receiving operation and checks
Restore the specified growing surface and turf. Check local levels, layer depth and drainage after the repair.
The correct treatment depends on the turf system and cannot be inferred from a photograph.

Rough formation establishes the broad geometry and material arrangement. It is the stage to correct major quantity errors rather than chase the final appearance.
Before moving material
Complete bulk movement and identify unaccepted areas.
Receiving operation and checks
Prepare for controlled movement and finishing. Check layer identity, drainage and access for the next machine.
Loose fill and weak formation should not be concealed by a finishing pass.
