Broader Reach. Timelier Decisions. Healthier Soils.
Triple the farms each field technician can reach — and act in time to protect yield and build soil health.

How we do it

Reach through the grower’s phone. Depth through one lab per zone.

Reach: every farm, every week

  • A weekly photo of the plant: vigor, growth and health.
  • A voice note on what was done on the farm.
  • All on WhatsApp, from the phone the grower already has. No equipment per farm.
Your agronomist sees every farm without driving out

Depth: getting ahead of the decision

  • Pooled sap samples by zone: 10 plants per field, showing what the plant is taking up right now.
  • Microscopy: counts of the functional groups of microorganisms that cycle nutrients.
  • The agronomic cognitive engine combines both readings with that field’s growth data and monitoring; your agronomist makes the call.
The cause, before it shows
A zone that behaves differently? That’s one more 10-plant sample and a few more photos on the grower’s phone. No extra sensor, no extra agronomist.
How it works · the way a good doctor works

From “not sure” to “here’s what to do.”

1
Spot it
The symptom
A weekly photo and voice note on WhatsApp, from the grower’s phone.
Monitoring + Field records
2
Understand why
The blood test and the scan
Sap and microscopy by zone: what the plant is taking up and what’s living in the soil.
Sap + Soil biology
3
Decide what to do
The specialist
The cognitive engine pulls it together and proposes the adjustment for that farm — no blanket recipes. Your agronomist decides.
Cognitive engine
4
Rebuild the soil
The treatment
A lab and a community bio-input plant in the area, set up by SiembraViva: biological inputs made locally.

Usage: JUACO data, Jun–Sep 2026. Results: individual farms, external lab, control where available. Carbon: Johnson, Ellington & Eaton (2015, preprint), 10.27 t C/ha per year over 4.5 years; we use 7 (× 3.67 = CO₂). The pilot measures it on your farms: baseline and endline, same point and method.

Cost vs. benefit

For the cost of a sensor: the reach of an app and the depth of a lab.

A sensorA labAn appJUACO
Cost per grower per yearUSD 250–470USD 1,400–1,800USD 5–10USD 320
Reach: covers your whole network without multiplying the cost✕ one device per farm◐ every sample billed✓✓
Depth: measures plant and soil, zone by zone◐ one point, one reading✓✕✓
Recommendation: specific to each farm, not a recipe✕ raw data only◐ a report, no action plan◐ one-size-fits-all✓

USD 320 per grower in year one. From year two, growers fund it from their input savings.

Sensor: weather stations, soil probes and in-plant sensors. Lab: 12 sap and 6 soil-biology tests a year at list prices. App: platforms companies use with their grower networks. Estimates based on published prices; SiembraViva research, October 2026.

The next step

A trial with your growers, side by side with your agronomist.

3 to 4 months · before transplanting
Preparation
Local lab and bio-input plant running. Soil and sap baseline.
One tobacco cycle
The crop
JUACO farms versus control farms, with your agronomist. Leaf quality measured against your criteria.
At the end
Decision
Three yeses and we scale.
1Did each technician triple their coverage without lowering the quality of support?
2Did the grower group cut input spend by 20% by the end of the cycle?
3Did beneficial fungal biomass rise by 30% by the end of the cycle?Soil rich in fungi and oxygen loses less nitrogen as nitrous oxide — a gas about 300 times more potent than CO₂.
