Measured in the field

A soil sensor on the plot, radar from orbit and ECMWF forecasts, fused into one answer: plant now, or wait.

Three layers of data

The probe knows the plot, the satellite sees the district, and the forecast sees the week ahead. No one source is enough on its own.

Sentinel-1 radar

Satellite radar

Reads surface moisture and flooding through monsoon cloud and Harmattan dust.

15%water to plant maize

ReadingThreshold

Soil sensor

Moisture and conductivity, read at the root zone of the plot itself.

Weather forecast

ECMWF’s medium-range model, corrected with readings from the ground.

93%

rainfall accuracy shown by fused forecast systems in West Africa

Built for the field, not the lab

Every reading must end in one action a farmer can take, on a phone they already own.

What we offer

All services

Planting advice

One plant-or-wait instruction for each plot, by USSD or voice in the farmer’s own language.

Soil sensor network

Rugged LoRa soil nodes and gateways for cooperatives, districts and farm programmes.

Data for lenders and insurers

Plot-level soil and weather records that reduce basis risk in index insurance and farm loans.

Produce market

Buyers order from many small farms at once; farmers accept an offer with one keypress and are paid by mobile money.

Fertiliser microdosing

When the soil is ready, 2 to 6 grams in the planting hole instead of a whole bag broadcast.

One plot, five signals

15%

Water by volume at the root zone. Maize needs about this much to establish; on sandy loam we look for 15–20%.

From soil to phone

Measure

Sensors on the plot read soil moisture and nutrients at the root zone.

Combine

Radar and ECMWF forecasts are fused with the readings from the ground.

Decide

The engine checks the soil against what the crop needs to germinate.

Deliver

One instruction goes out by USSD or voice, in the farmer’s language.

The ground corrects the model

ECMWF’s land model estimates soil moisture from rain, sun and evaporation, but Africa has few stations to check it against. A Kalman filter weighs each reading from our sensors against that estimate, pulling the forecast back toward what is really in the soil.
