Application domain
Two zones of the same field are not worth the same. The point is knowing which ones, and why.
Our work
Map a parcel’s agronomic potential continuously, to separate what satellite imagery conflates: depth, texture and available water.
Reading the soil
Each piece of information has its depth.
0 – 0.3 m
0.25 – 0.5 m
0 – 1 m
0.6 – 1.3 m
0.5 – 2 m
The questions
Yield has always varied from one end of the field to the other. The question is not observing it — it is knowing its physical cause.
Shallow soil, plough pan, a clay pocket, waterlogging. Resistivity mapping separates these cases, which satellite imagery conflates.
Our expertise Separate depth, plough pan, clay pockets and waterlogging — cases satellite imagery conflates.
Benefits
Zoning based on soil — not on one season's vigour — stays valid for years. It is the base layer of any variable-rate strategy.
Our expertise Base the zoning on the soil, so variable-rate decisions stay valid beyond a single year.
Benefits
The plans are lost, the drains are not. Radar and resistivity find them without opening a trench.
Our expertise Recover the drain layout with radar and resistivity, without opening a trench.
Benefits
Usable depth and texture govern water holding. Resistivity approaches both directly, and continuously.
Our expertise Approach available water through usable depth and texture, continuously.
Benefits
Investigation strategy
Agriculture demands area covered at the right cost. Towed resistivity is unbeatable here; radar comes in as a targeted complement.
ARP®
The backbone. Three depths measured at once at working speed, across tens of hectares a day.
GPR
Precise location of drains and interfaces, on the zones where resistivity flags an anomaly.
EMP
A useful complement on saline or highly conductive soils, where resistivity alone saturates.
Three depths
ARP® does not measure one depth but three at once. Switch channel and the map transforms in front of you. The deeper you go, the broader the structures — the volume of soil integrated grows with depth.
—
Channel V1: a real export from a parcel mapped by GEOCARTA. Channels V2 and V3: simulated from V1 pending the real exports — a deeper channel integrates a larger volume of soil, hence broader structures.
Projects
The contrast is sharp: a broad conductive zone to the west, a resistive zone to the east, separated by a clean transition. That kind of opposition usually reflects a change in texture or soil depth — two parameters that bear directly on water reserve and on how the parcel behaves in a dry year.
One map per investigation depth, georeferenced and ready to overlay on your existing layers.
