Why it cannot be optimised without measurement
A humic conditioner does not act within a single season — the effect builds over years and the application is repeated after three to four. A one-off observation says nothing about it. Without measurement the rate is a guess, and a guess has two equally expensive failure modes: applying more than the soil needs, or so little that no effect appears and the money is wasted either way.
Two of the declared functions of humic substances are directly measurable — water retention in the soil profile and the change in the ionic environment. Those are what HUMEUS Probe tracks continuously.
Two layers of measurement
| Continuous — in-field probe | Periodic — laboratory |
|---|---|
|
volumetric soil moisture by depth soil temperature electrical conductivity (EC) as an indicator of ion concentration and salinity pH by ion-selective probe |
organic carbon content (Cox) humic acids — total and free sorption (cation exchange) capacity available nutrients N, P, K, Mg, Ca contaminant levels |
A probe does not replace the laboratory. Neither humic acid content nor sorption capacity can be measured by a probe. EC and pH probes also drift over time, so they are calibrated against a laboratory sample from the same point and date. Anyone claiming a probe replaces the analysis is selling something other than what they say.
What the system does
Field and analysis records
Every field has its own record: incoming analysis, control analyses, soil type and application history. Paper certificates stop getting lost.
A trend, not a single figure
One sampling result proves nothing. The system shows the development over time — whether Cox is rising, whether moisture holds, whether soil reaction shifts.
Rate proposal
From the measured trend and the crop structure it calculates next season's rate and the date of the next control analysis.
Batch traceability
Each application records the batch number and its certificate of active content. It stays clear exactly what went onto which field and when.
Export for inspection
A report for an inspection authority or certification body, including proof of raw material origin — which matters under an organic regime.
Alerts
The system flags the due date of a control analysis and warns when a monitored parameter moves outside the expected range.
How it runs
1. Incoming analysis and probe installation
Sampling and laboratory analysis establish the baseline. Probes are installed in the root zone at representative points across the field.
2. Continuous recording
Probes log moisture, temperature, EC and pH at a regular interval. Readings are transferred to the system as they are taken.
3. Application record
Each application records the rate, date, field and batch number together with its certificate.
4. Control analysis
A control sample is taken on schedule. It also serves to calibrate the probes, so that their drift does not work its way into the conclusions.
5. Rate proposal for the next season
The system compares the measured trend against the expected one and proposes a rate. The decision stays with the grower — the system supplies a basis, not an instruction.
Soil answers slowly — so it has to be listened to continuously
A probe will not measure humic acid content. It measures moisture, temperature, conductivity and pH — and their trend between analyses is what a decision can rest on.
Data and access
- The data belongs to the customer. Export to a common format at any time, with no conditions and no tie to further purchases.
- Every entry carries an audit record — who created or changed it and when. Without that the records would not stand up to an inspection.
- Access through login with two-factor authentication, with permissions by role (grower, agronomist, inspection).
- Data is not passed to third parties and is not used for any purpose other than operating the system.
