Use our free tool to map the variability in your field and see where you could save input costs. Last year, sunflower growers who used our service reduced their fertiliser use by 37% and maintained the same yield.
A field-average rate treats every hectare the same. FVA gives you the zone map that helps turns a blanket rate into a targeted plan — with the yield safely intact.
From postcode to detailed report, same day. No installs, no equipment, no visit.
Free for anyone. Not tied to any product purchase or Syngenta contract.
Prioritise between fields with our variability score, and within field with a productivity rating per zone.
Powered by Cropwise, used on 100+ million hectares by 40,000+ growers.
One short form. Your report in 6 hours. Your 2027 fertiliser plan sharper.
Postcode, size in hectares (minimum 0.5 ha), main crop.
5 years of satellite imagery combined into one average map. Report ready in about 6 hours.
Under-performing zones flagged. Over-performing zones flagged. Your input plan writes itself.
Further services to calculate crop nutrient demand and vary rates across field.
The report shows which zones under-perform and which over-perform. See where you could optimise input rates to avoid over or under fertilising.
The Variability Index combines two things: how different the parts of your field are (heterogeneity) and whether those differences hold over time (consistency).
How much crop performance varies across your field. We show the zones. The bigger the difference between zones, the higher the heterogeneity.
How stable those zones have been across 5 years of history. A field with high consistency responds well to variable-rate. A field with low consistency makes it harder to apply rates precisely within the field.
Free field-variability report. Zone-by-zone insight, no form on this page.
Fields have zones that already perform above average and zones that under-perform. FVA shows you which is which, so you match rate to real potential — save on the weak zones, optimise on the strong ones.
