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.

SiembraViva · JUACO — Regenerative intelligence for exporters and aggregators

You have seen similar proposals · here is the difference

Know in time — at scale.

Some extend your field team’s reachbut they record what has already happened.

A few look inside the plant and the soilbut one farm at a time.

JUACO does bothThree times the reach for your agronomists, with the depth to catch problems early.

Scores 0–10: SiembraViva’s assessment of what each company publishes (September 2026).

Why it matters

You can’t measure the future. JUACO shows what drives what — and why.

All data looks backward. JUACO shows what a decision is likely to produce before you have to live with it.

Anticipates

It shows the trend mid-season, while there is still time to act.

Experience, without the cost

The experience you can’t afford to buy — the kind you only get by losing a crop.

Context, not recipes

It doesn’t say “do X.” It says “under these conditions, X leads to Y.” That is why it avoids blanket recipes.

Outliers make it sharper

When a result doesn’t fit, it isn’t thrown out — it refines the model.

The role of your agronomy team

Your agronomist makes the call. JUACO doesn’t replace them — it triples their reach.

The judgment is there; the view between visits isn’t.

Three times the farms

Sees every farm in the area weekly, and visits where it counts.

More depth

Sap and soil biology show what a field visit can’t.

From firefighting to prevention

Between visits, someone is still watching the farm.

Know-how that stays

Every decision and its outcome is recorded, so it doesn’t walk out the door with people.

How it works · the way a good doctor works

Step 2 · The blood test and the scan

What’s really going on?

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

Soil biologyThe scan: the life in the soil.

The cause, before it showsNot once the damage is on the leaf.

Soil fungiµg per gram · Coffee, Nicaragua

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.

Step 3 · The specialist

What should we do in this field?

Three schools of thought, one decisionSap nutrition (Kempf), the soil food web (Ingham) and compost biology (Johnson). The engine decides which one should lead in that field.

No recipes, no guessworkIt works only from vetted agronomic criteria and the farm’s own data — it doesn’t improvise. Your agronomist has the final say.

Learns from every new data pointIt checks each recommendation against what actually happened.

Step 4 · The treatment

More than an app. We set up the lab and the bio-input plant.

A lab in the growing areaSap and soil-biology testing close to the farms, not in a city lab. SiembraViva installs it and trains the local operator.

Community bio-input plantCompost and vermicompost made from local crop residues and inoculated with soil biology native to the area.

Capability that stays localTrained rural young people running the microscope and the bio-input plant in their own community.

Persian lime · Sierra Puebla–Veracruz, Mexico. Pilot zone on vermicompost from the bio-input plant versus two adjacent zones on a synthetic program (urea and others), January–August 2026; the grower reports the same tree count in each. The harvest reflects a single application. Costs at Colombian list prices, in Colombian pesos (August 2026).

What to expect, and when

Costs come down first. Yield follows.

Short term · first cycleStop applying what the plant isn’t using.

Less synthetic fertilizerSap shows what’s in excess before the next application.

Inputs made on siteThe bio-input plant replaces part of what is bought today.

This is what the trial measures

Medium term · years 2–3Once soil biology is established.

Higher yieldA biologically active soil supplies nutrients on its own.

More resilienceTo drought, heavy rain and input-price spikes.

Environmental impact · soil regeneration

Impact you can verify — measured farm by farm.

Less synthetic fertilizer

Making and applying nitrogen is one of the largest emission sources in a crop.

Metric: kg of nitrogen per hectare

Living soil

Fungi, bacteria, protozoa and nematodes, counted under the microscope.

Metric: resilience index

Residues back to the soil

The bio-input plant turns farm and kitchen waste into inputs.

Metric: tonnes processed

Structure and oxygen

Compacted, oxygen-starved soil releases nitrous oxide, a gas about 300 times more potent than CO₂. Relieving compaction prevents it and lets soil biology thrive.

Metric: soil structure test in monitoring

No salinization

The usual concern with compost. After two years of heavy use, conductivity went down.

Metric: electrical conductivity

Soil carbon

Johnson (2015, preprint) reports about 10 t/ha per year once fungi and bacteria reach 1:1. We use 7 as a conservative reference.

Metric: baseline and endline, same point and method

Measured regeneration · vegetables, Antioquia, Colombia

We noticed that after the nitrogen application the stem grew faster and the leaves turned greener 🌱

But two weeks later growth dropped below where it was, and pest signs are showing.
