Book the Mobile LabPutting AI in every rai
Every layer of your field. One clear answer.
Rai stacks what is known about one plot (satellite greenness, the soil map, your lab test, this season's rain and haze), lines it up with what Thailand's crop records already show, and tells farmers and breeders what to do next. With the evidence and the doubt beside every number.
Pilot partners use RaiOS, the platform, today. Self sign-up and the public crop world are coming next.

"Should I add nitrogen this week, given the rain forecast?"
Not this week: your rice is 103 days old and already past the stage where nitrogen pays.

01 · The problem
Today, the big decisions are made late, or blind.
Take one rice plot in Nakhon Ratchasima, 45 days after planting. Here is the same plot read two ways.
From a soil sample taken 30 days ago
"Nitrogen is below target. Apply nitrogen now."
The only instruction a month-old sample can support.
Measured yesterday
"Flush the plot, hold the nitrogen, measure again in five to seven days."
Nitrogen is 17 mg/kg, below target. But salinity is about 4.2 dS/m, and rice starts losing yield above roughly 3.0.
Same crop, same soil, opposite instruction. The difference isn't a better laboratory. It's a fresher number. Illustrative values.
The evidence is scattered
Genebanks, field trials, weather records, soil surveys and papers each keep their own format, names and terms. Nobody can act on evidence they can't line up.
A cheap probe isn't a measurement
In our own 48-day test on six plots, a low-cost probe's nitrogen, phosphorus and potassium lines moved in exact step with one conductivity reading (correlation 0.9999). One number, dressed up as three.
A new variety takes many seasons
Most crosses never produce a winner, and every failed cross uses field space and a season. Meanwhile the climate the variety must face keeps moving.

02 · What Rai does
Knowledge above data.
Data alone doesn't decide anything. Rai lines up independent public records into one knowledge layer, so a farmer, a breeder or an agency officer gets an answer that can cite its evidence, down to the record, the place and the season.

Cross RD6 with a Boa Vista × Cenit bridge parent, then backcross four times: 73 % of 1,900 simulated runs gave at least one line with both blast-resistance genes within 3.5–7 years.

03 · How it works
Two loops on one knowledge layer.
The fast loop advises a farm every week. The slow loop helps breeders choose crosses over years. Both use the same rice growth model, so every season in farmers' fields sharpens the breeding predictions.
