Furrow Probe, shipping spring 2027
Soil that
reports back.
A single stake in the ground measures moisture, temperature and carbon at four depths, then sends it to your phone every 15 minutes. Water when the roots need it, not when the calendar says so.

A field you can read like a weather report
This is a real probe pattern from a barley field over three days. Watch how the surface dries by afternoon while the deep roots hold steady, and how a single rain changes everything.

Questions
Write to field@furrow.example for anything else.
How many probes does my farm need?
One probe covers about four hectares of even soil. Start with one per soil type and add more where you see differences.
Do I need internet in the field?
No. Probes talk to a small gateway up to 8 km away by long range radio. A cellular version is available for remote paddocks.
What does the data plan include?
The app, alerts, unlimited history, CSV export and the API. It is $6 a month per probe and the first year is included with every pre-order.
When will my probe ship?
The first batch ships in March 2027, in the order pre-orders were placed. We will email tracking the day it leaves.
Reserve your probes for spring
A $49 deposit per probe holds your place in the first batch. Fully refundable until we ship.
