Why Calculation Details matter
RanchAssist is designed so users can audit the assumptions behind a planning result. Before using the output for purchasing, scheduling, budgeting, or field decisions, review the source inputs and any user-editable assumptions.
Core calculation relationships
- Coverage uses tank gallons ÷ target GPA to estimate acres per tank.
- Project carrier uses acres × target GPA.
- Product requirement uses the user-entered label rate and the applicable acres or carrier basis.
- Calibration uses boom/nozzle geometry, travel speed, and measured nozzle flow or catch-test data to calculate GPA.
- Cost calculations use user-entered package price/size and operating costs; RanchAssist does not provide live chemical prices.
Results to review together
- Total carrier volume
- Total product quantity
- Product per tank
- Full tank count
- Partial-last-tank water and product
- Acres per tank
- Gpa from calibration
- Acres/hour and carrier/hour
- Tank duration
- Product cost/acre
- Total job cost and cost/acre
How to sanity-check the result
Change one important assumption at a time and confirm the result moves in the direction you expect. If a small change creates a very large result change, check units, percentages, duplicated rows/features, and any hidden Advanced settings.
Rounding and purchase quantities
Where the tool converts a calculated need into purchasable whole units—such as bales, rolls, packages, loads, or other discrete quantities—the purchase quantity may round upward even when the mathematical requirement is fractional. Review Calculation Details for the current tool behavior.
Planning limitation
The pesticide or herbicide label is the controlling source for legal rate, PPE, restrictions, re-entry, grazing/haying intervals, environmental precautions, and tank-mixing requirements. RanchAssist does not recommend products or off-label rates; users must enter the label rate themselves.
