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.

Bio-inputs + Lab

Step 1 · Reach: the grower’s phone

How is the crop doing this week?

A photoVigor, growth stage, plant health and soil.

A voice noteEverything done on the farm, on record.

Every week, no travel neededThe grower sends it on WhatsApp.

Step 2 · Depth: one lab per zone

What’s really going on?

SapThe blood test: what the plant is taking up right now.

Soil biologyUnder the microscope: the functional groups that cycle nutrients.

By zone, 10 plants per fieldA zone that behaves differently? One more sample and a few more photos. No extra sensor.

Program field versus its control. Fungi rose from 3 to 153 under the program; the control stayed at 6.

Calcium in sapppm, new leaf · Vegetables, Colombia

Five readings, one trend: calcium is falling — visible in the sap before it shows on the leaf.

Actual lab data, as shown in each farm’s audit view. Each point is one sample.

What your agronomist sees · three times the reach

One technician, three times the farms. And a clear call list.

per hectare per year (7 t of carbon) at a 1:1 fungal:bacterial ratio · a conservative reference on David Johnson, NMSU (~10 t C)

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 sensor	A lab	An app	JUACO
Cost per grower per year	USD 250–470	USD 1,400–1,800	USD 5–10	USD 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.
