Automated Farm Input Cost Per Acre Report
Every Monday, WebRun opens Granular, reads applied input quantities and costs by field for the current season, calculates cost per acre for seed, chemicals, and fertilizer on each field, updates a Google Sheets report, and posts a weekly cost summary to Slack so you can course-correct before costs run away.
How do I automatically calculate and report input cost per acre by field?
WebRun opens Granular every Monday, reads applied seed, chemical, and fertilizer quantities and costs by field, calculates cost per acre in Google Sheets with a category breakdown, and posts a Slack summary flagging fields over budget. Season-to-date averages appear every week.
- Over-budget fields flagged weekly before costs compound
- Category breakdown shows whether seed, chemicals, or fertilizer is driving overruns
- Season-to-date averages provide a benchmark for year-over-year comparison

Questions, answered
Does it include land rent or machinery costs in the per-acre calculation?
By default it covers seed, crop protection, and fertilizer inputs from Granular. Add land rent or machinery cost columns to the Google Sheet and WebRun will include them in the totals.
How does it know my season budget per acre?
Enter a budget per acre per field in the Google Sheet configuration tab. WebRun compares the running cost against that figure each week and flags fields that exceed it.
Can it report on prior seasons for comparison?
Yes. The Google Sheet retains weekly snapshots, so you can compare cost per acre at the same point in the season year over year.
