Why it matters

Most crops are underfed or overfed — and you can't see it.

Even small nutrient imbalances reduce yield, crop quality and crop health. Over-fertilisation of wrong nutrients can limit growth just as much as too little.

And it happens every season.

The reality

Up to

30–50%

of nitrogen is not used by the crop.

Phosphorus efficiency can be as low as

10–25%

of what you apply.

And many farmers apply fertiliser based on

How it works

Precision nutrition made easy. Four simple steps.

Collect leaves of your crop

We show you exactly what to sample. No special tools needed. Takes 5 minutes per field.

Send to lab

A sap test is to a plant what a blood test is to a human. We analyze all plant nutrients — macro, micro, and trace elements — and automatically check ratios, mobility, and antagonisms.

Lab analysis

Tested by NovaCropControl, the leading Dutch plant-sap laboratory.

Get your precision tank mix on your phone

We create a spray recommendation using your available products, optimized for maximum response, crop stage, and application conditions. Includes EC and pH optimization for maximum leaf absorption.

•

Unnecessary late N application: 39 kg N × €0.80 = €31/ha — plant didn't need it

•

Yield drag from early-season N dip: Slower start before recovery = €20–80/ha lost

•

Quality downgrade from excess N late: 3–6% sorting loss = €10–80/ha

•

Environmental compliance risk: Leaching exposure near nitrate limits

Sap testing surfaced hidden calcium and boron shortages. I cut nitrogen by 22%, lifted yield 14% — first season paid for itself in week three.
