Spend where the soil asks for it
Acid patches get the lime they need and parts already at target get none. Often the total goes down while the correction goes up.

Variable-rate lime and fertiliser, zone by zone.
One rate across a variable land over-applies in some places and under-applies in others. We turn grid soil results into application zones and export a prescription your spreader can run.
Why it matters
Why apply by zone
Built on measured soil
Zones come from GPS grid sampling, topsoil and subsoil, not from a guess or a single composite sample.
Ready for the monitor
Prescriptions are exported as shapefiles that load into John Deere, Case IH and New Holland displays.
Honest about limits
Where a correction is larger than one pass should carry, we say so on the map rather than quietly capping it.
How we do it
Four steps, the same way every time.
1
Sample
GPS grid soil sampling, topsoil and subsoil.
2
Map
Soil maps per element and depth, interpreted against the crop's targets.
3
Prescribe
Rates per zone for lime, gypsum, P and K, rounded to what the spreader can apply.
4
Verify
The next survey shows whether the correction did what it was meant to.
What you get back
What lands on your desk.
- A zone map per land, with the rate for each zone
- Totals per product, ready for ordering from your supplier
- A shapefile for the spreader display and a PDF map
- A note wherever the correction needs more than one season
Questions
Questions farmers ask us.
Which spreaders and displays can use the files?
We export standard shapefiles, which load into John Deere, Case IH and New Holland displays and most other rate controllers.
Does variable-rate liming save money?
Often, but not always. On very variable lands the saving can be large; on uniform lands a single rate may be fine, and we'll tell you so.
Can you use my existing soil data?
If it is GPS-referenced and recent enough, yes. Otherwise we resample on a grid first.
