How it ships

Field console  /  v4  /  vineyard & orchard

Every root zone, on one quiet screen.

TERRA reads moisture, temperature and flow across every block you farm — then tells you the one thing worth doing today. Scroll to walk the console, or jump straight to a panel.

01

It reads the soil, not the forecast.

Three probes per block, at 20, 40 and 60 centimetres. You see where the water actually is — not where an app guessed it might be. Fourteen days of history sit behind every number.

  • 90-second sampling
  • Battery life measured in seasons
  • Works offline, syncs when it can

02

Every block, at a glance.

The map is the index. Thirsty parcels warm up, healthy ones stay quiet, and you can go from twenty-four blocks to one root zone in a single tap.

  • Colour tracks deficit, not rainfall
  • Drawn from your own boundary file
  • Tap a parcel to try it

03

A plan you can argue with.

TERRA proposes tonight’s windows and the draw they’ll cost. Switch a zone off and the total moves with you — nothing is locked until you say so.

  • Per-zone override
  • Live cost in cubic metres
  • Pushes straight to your controller

04

Set the rule. See it back-tested.

Drag the threshold and TERRA replays the last fortnight against it, so you know how noisy a rule is before it starts waking you at four in the morning.

  • Instant back-test
  • Quiet hours respected
  • SMS, push, or nothing at all

05

Paperwork that writes itself.

Water-use reporting is a legal chore. TERRA keeps the audit trail as it goes and hands you the finished document on the first of the month.

  • PDF, CSV or XLSX
  • Signed and timestamped
  • Five years of retention

Why growers keep it

Less water, same fruit

Irrigating to measured deficit instead of a calendar cut draw by roughly a third across the 2025 season.

4 min

Morning round, done

One screen replaces the walk, the spreadsheet and the three phone calls that used to start every day.

Subscriptions to chase

Hardware is yours, data is yours, exports are open. Nothing holds your season hostage.

“I stopped irrigating on Tuesdays because it was Tuesday.”
— a grower, somewhere with better weather than here

About this page

This is a sample, built to be looked at closely.

TERRA is invented — the product, the numbers, the grower. Everything else is real: hand-written HTML, CSS and JavaScript, no framework, no build step, no third-party requests. The fonts are self-hosted and subset, the charts and the map are inline SVG drawn from data at runtime, and the whole page weighs a little over a hundred kilobytes.
