Soil Passport™ FAQ

Answers about soil intelligence, soil testing, biomass, SPX™ climate technologies, biochar, carbon MRV, climate markets, industries, solutions and partnerships.

01 — Soil Passport™
Q

What is Soil Passport™?

Soil Passport™ is a UK technology and digital intelligence platform that connects soil intelligence, soil testing, agricultural biomass, SPX™ climate technologies and carbon MRV data into one evolving ecosystem.

Q

What does Soil Passport™ do?

It creates a digital profile for agricultural land — combining soil testing, AI predictions, satellite intelligence, soil carbon data and biomass data — and connects that intelligence to SPX™ climate technologies and carbon measurement, reporting and verification (MRV).

Q

What problem does Soil Passport™ solve?

Soil data, biomass management, bioenergy conversion and carbon accounting are usually managed as separate, disconnected activities. Soil Passport™ is built to connect them into one continuous information and value cycle.

Q

Is Soil Passport™ a soil testing company or a technology platform?

Soil Passport™ is a technology and IP platform, not a soil-testing hardware manufacturer. Soil testing devices, satellite data and other inputs feed into the platform, which turns that data into a digital soil intelligence record.

Q

What is the relationship between Soil Passport™ and SPX™?

Soil Passport™ is the overall digital intelligence platform. SPX™ is the climate technology and product ecosystem built on top of it, covering biochar, bio-oil, bio-tar, biohydrogen, bioenergy and carbon/MRV infrastructure.

Q

Who can use Soil Passport™?

Farmers, FPOs and cooperatives, biomass-processing plant operators, technology and implementation partners, enterprises sourcing traceable bio-based products, investors, and carbon/MRV and research partners.

Q

What is the long-term vision of Soil Passport™?

To build a connected ecosystem where every participating field, biomass source, processing facility and bio-based product can have a trusted digital identity — from soil intelligence to circular bioeconomy intelligence.

02 — AI & Satellite Soil Intelligence
Q

How does Soil Passport™ use AI?

AI is used to turn raw soil, satellite, crop and historical data into predictions and recommendations — moving beyond "what is in the soil" to "what it means, what could happen next, and what to do about it."

Q

How does Soil Passport™ use satellite data?

Satellite imagery and remote-sensing datasets are combined with field-level soil testing to build a fuller picture of a field's condition — helping identify patterns that ground-level testing alone cannot capture.

Q

What is satellite soil intelligence?

Satellite soil intelligence is the use of remote-sensing data — vegetation indices, moisture and other field-level signals — as an additional data layer alongside physical soil testing, to monitor land at scale.

Q

Can satellite data replace physical soil testing?

No. Satellite data complements physical soil testing rather than replacing it — ground-truthed measurements (NPK, pH, EC, moisture, organic carbon) remain the foundation that satellite and AI layers are built on.

Q

How does Soil Passport™ combine satellite and field data?

Field-level soil-testing results, farm records and satellite datasets are brought together in the Soil Passport™ platform to create one evolving digital soil profile per field, rather than isolated, one-off reports.

Q

What soil information can Soil Passport™ analyse?

Soil parameters tracked include pH, EC, NPK, soil organic carbon, moisture, temperature, salinity, crop and field information, and historical measurements over time.

Q

How can AI support soil intelligence?

AI can help identify trends across a farmer's testing history, flag anomalies, support recommendations for soil and crop management, and feed structured data into carbon and biomass workflows.

03 — Soil Testing & Soil Carbon
Q

What is Soil Passport™ soil testing?

A physical soil testing device measures core soil parameters in the field; the results sync to the Soil Passport™ app and become part of a farmer's or field's digital soil record.

Q

What soil parameters can be measured?

NPK (nitrogen, phosphorus, potassium), pH, EC (electrical conductivity), moisture, temperature, salinity and soil organic carbon are among the parameters the platform is designed to record.

Q

What is soil organic carbon?

Soil organic carbon is the carbon stored in soil organic matter. It is a key indicator of soil health and fertility, and an increasingly important measure in climate and sustainability reporting.

Q

Why is soil organic carbon important?

It affects soil structure, water retention and fertility, and is central to soil-carbon-related climate projects — making consistent, traceable measurement valuable for both farmers and carbon programmes.

Q

How can soil carbon be monitored?

Through repeated, consistent soil testing over time, combined with field records and — where relevant — satellite data, to track changes in soil organic carbon and other conditions.

Q

Can Soil Passport™ track changes in soil carbon?

The platform is designed to support baseline measurement, ongoing monitoring and change tracking of soil carbon over time as part of its MRV-oriented data architecture.

Q

How does soil testing support the Soil Passport™ ecosystem?

Soil testing is the starting point of the ecosystem — it creates the baseline data that later connects to farm intelligence, biomass tracking, SPX™ technologies and carbon MRV.

04 — Biomass & Circular Bioeconomy
Q

What is biomass intelligence?

Biomass intelligence is the identification, mapping and tracking of agricultural residues — what biomass exists, where, in what quantity, when it is available, and how it can be collected and converted.

Q

What agricultural waste can be used as biomass?

Crop residues, husks, stalks and other agro-waste are typical feedstocks — the specific types depend on the region, crop mix and the SPX™ technology pathway being deployed.

Q

How does Soil Passport™ connect farmers with biomass?

The platform can record the journey from farmer to field, crop, residue, collection and processing, giving biomass-processing plants visibility into supply and farmers visibility into the value of their residues.

Q

What role do FPOs play?

Farmer Producer Organisations (FPOs) help aggregate biomass across member farms and act as a collection and coordination layer between individual farmers and biomass-processing plants.

Q

How can agricultural waste become a climate resource?

Rather than being burned or left as waste, agricultural residue can be collected and converted through SPX™ technologies into biochar, bio-oil, bio-tar, hydrogen, syngas or bioenergy.

Q

How is biomass mapped and aggregated?

Through farmer and FPO data, collection-network information and field records combined in the platform — giving a structured, traceable view of biomass availability and flow.

Q

What happens to biomass after collection?

Collected biomass is processed through SPX™ conversion technologies — pyrolysis, gasification and related processes — into one or more SPX™ products, depending on the plant's configuration.

05 — SPX™ Climate Technologies
Q

What is SPX™ Technology?

SPX™ is the product and technology ecosystem operating under Soil Passport, covering biomass conversion into biochar, bio-oil, bio-tar, biohydrogen, bioenergy and carbon measurement/MRV infrastructure.

Q

What is SPX BioChar™?

SPX BioChar™ converts agricultural residue into stable, carbon-rich biochar through pyrolysis — for use as a soil amendment and a long-term carbon-removal pathway.

Q

What is SPX BioOil™?

SPX BioOil™ uses fast pyrolysis to convert biomass into a liquid fuel and renewable chemical feedstock, for industrial heat, power and low-carbon fuel applications.

Q

What is SPX BioTar™?

SPX BioTar™ is a thermal-conversion pathway that produces a dense, viscous bio-tar used as an industrial feedstock — including bio-based binders, sealants and adhesives.

Q

What is SPX Syngas™?

Syngas is a combustible gas co-produced during pyrolysis and gasification; it can be captured for on-site energy use or as a feedstock for further conversion, including to hydrogen.

Q

What is SPX BioH₂™ (Biohydrogen)?

SPX BioH₂™ converts biomass-derived syngas into clean hydrogen through gasification, reforming and purification — for industrial, mobility and fuel-cell applications.

Q

What is SPX Power™ (Bioenergy)?

SPX Power™ converts biomass into electricity via combustion or gasification, supporting distributed and rural power generation.

Q

How does SPX™ technology convert biomass?

Depending on the pathway, biomass is processed through pyrolysis, gasification, reforming or combustion — each producing a different primary product (biochar, bio-oil, bio-tar, hydrogen or electricity) plus potential co-products.

Q

Can SPX™ technologies be deployed by project partners?

Yes. Soil Passport licenses and partners rather than operating every project itself — technology, plant and project partners can deploy SPX™ pathways under a partnership or licensing model.

06 — Biochar & Carbon Removal
Q

What is biochar?

Biochar is a stable, carbon-rich solid produced by heating biomass in a low-oxygen pyrolysis reactor. It can be applied to soil to improve structure and water retention while storing carbon long-term.

Q

How is biochar produced from agricultural biomass?

Crop residue and other agro-waste is fed into a pyrolysis reactor and heated (typically 350–700°C) in a low-oxygen environment, converting it into biochar plus co-products such as syngas and bio-oil.

Q

How can biochar contribute to carbon removal?

Converting biomass into biochar locks carbon into a stable solid form that resists decomposition for a very long time, rather than that carbon returning to the atmosphere through natural decay or burning.

Q

How long can carbon remain stored in biochar?

Durability depends on feedstock and production conditions and is assessed under recognised carbon-removal methodologies — Soil Passport provides traceability data to support that assessment rather than setting durability figures itself.

Q

What factors determine biochar carbon-removal potential?

Feedstock type, pyrolysis temperature and process conditions, and how and where the biochar is applied all affect its carbon-removal characteristics.

Q

Can biochar be used in soil?

Yes — biochar applied to agricultural soil can improve soil structure and water retention alongside its carbon-storage role.

Q

How is biochar tracked after production?

Through the SPX BioChar™ digital passport and traceability layer, which records the biochar's journey from biomass source to soil application.

Q

Can biochar generate carbon-removal credits?

SPX BioChar™ provides the traceability and MRV data layer that supports carbon project development, but credits themselves are issued by independent carbon standards and registries using recognised methodologies — not by Soil Passport.

07 — MRV & Carbon Credits
Q

What does MRV mean?

MRV stands for Measurement, Reporting and Verification — the process of measuring an environmental outcome, reporting it transparently, and having it independently verified.

Q

Why is MRV important for carbon removal?

Carbon-removal claims need credible, verifiable data to be trusted and to qualify under recognised standards — MRV is the mechanism that provides that credibility.

Q

How does Soil Passport™ support MRV?

The platform is designed to connect soil, biomass, production and project data into structured MRV workflows that can feed into independent verification and registry processes.

Q

What data is required for carbon-removal MRV?

Typically feedstock and process data, soil and field baseline measurements, production records, and ongoing monitoring data — the specific requirements depend on the methodology used.

Q

What is carbon additionality?

Additionality means the carbon benefit would not have happened without the project or intervention — a core requirement that independent standards assess before issuing credits.

Q

What is carbon permanence?

Permanence refers to how long removed or avoided carbon remains out of the atmosphere — an important factor in how different carbon-removal pathways and credits are assessed.

Q

What is carbon traceability?

Carbon traceability is the ability to trace a carbon outcome back through its full chain — from biomass source, through processing, to application or storage — supporting MRV and credit issuance.

Q

Does Soil Passport™ certify carbon credits?

No. Soil Passport provides the digital data and traceability infrastructure; carbon credits are certified and issued by independent carbon standards and registries, which remain independent of the platform.

Q

Who verifies carbon-removal projects?

Independent, third-party verification bodies operating under recognised carbon standards and registries — not Soil Passport itself.

Q

How are carbon credits issued?

Through the relevant certification body or registry, once a project's measurement, additionality, permanence and other criteria have been independently verified against an eligible methodology.

Q

Can Soil Passport™ connect projects with carbon markets?

The platform and SPX™ Carbon™ infrastructure are designed to support carbon project development and the data layer needed to engage with carbon markets, working alongside independent registries rather than replacing them.

08 — SPX™ Marketplace
Q

What is SPX™ Marketplace?

The Soil Passport Marketplace is the commercial layer connecting projects, technologies, environmental assets and buyers across the Soil Passport ecosystem, organised into three categories: carbon, technology and biomass.

Q

What products can be listed?

Carbon-related environmental assets, climate and biomass-conversion technologies, and biomass supply opportunities are the three categories the Marketplace is built around.

Q

Can biochar be sold through SPX™ Marketplace?

Biochar and other SPX™ products can be part of the biomass/technology side of the Marketplace, connecting producers with potential industrial or agricultural buyers.

Q

Can bio-oil and bio-tar be sold through the marketplace?

Yes, in principle — bio-oil, bio-tar and other SPX™ outputs fit the same model of connecting producers with buyers through the Marketplace's technology and biomass categories.

Q

Can carbon-removal assets be listed?

Carbon-related environmental assets are one of the Marketplace's three core categories, intended to connect carbon project developers with buyers, alongside independent registries and standards.

Q

Who can buy SPX™ climate products?

Enterprises, technology companies, project developers and other organisations seeking traceable biomass-based products, technologies or carbon-related assets.

Q

Who can become a supplier?

Biomass suppliers, SPX™ technology operators, and project developers producing eligible products or environmental assets can participate as suppliers on the Marketplace.

Q

How are products and projects verified?

Through the platform's traceability and digital product passport data, combined — for carbon-related assets — with independent MRV and registry verification.

Q

How does the marketplace connect with MRV?

MRV data underpins the credibility of what's listed — particularly for carbon-related assets — so buyers can see a traceable record behind each product or project.

09 — Farmers, Projects & Partners
Q

How can farmers participate?

Farmers can use the Soil Passport™ app for soil testing, digital farm records and biomass opportunities — most farmer participation flows through FPOs, cooperatives or local project partners.

Q

How can FPOs participate?

FPOs can aggregate farmer data and biomass across member farms, acting as a coordination layer between farmers and biomass-processing plants or project developers.

Q

How can biomass suppliers participate?

Biomass suppliers can register supply and collection information through the platform, connecting with SPX™ plants and project developers who need feedstock.
