PROPELOO

AGRITECH / AGRICULTURAL TECHNOLOGY PLATFORM

Build agricultural software that works in the field, not just the office.

PROPELOO engineers agritech platforms — from farm management systems and crop monitoring through IoT sensor integration, satellite imagery analysis, supply chain traceability and the offline-capable mobile apps that work without connectivity. Agricultural technology must work where agriculture happens.

Agricultural software that requires 4G connectivity to function will not be used in the 40% of agricultural land without reliable coverage.

Agritech has a unique constraint that most software does not: users are often in fields, greenhouses and storage facilities where connectivity is intermittent or absent. Software that fails when offline is software that fails when most needed. A farm manager recording crop observations needs that data captured immediately, even if it syncs later. A supply chain traceability system must scan produce at harvest, not only at the first point with connectivity. PROPELOO builds agritech with offline-first architecture as a baseline requirement, not a post-launch enhancement.

The agritech platform stack.

    Blockchain or database-backed supply chain traceability — harvest to shelf tracking, QR code generation for consumer transparency, certification documentation management and recall response.

  • Offline-first Mobile App

    React Native mobile app with local SQLite database for offline operation, background sync when connectivity returns, conflict resolution for concurrent edits and field-optimised UX.

  • Farm Analytics

    Yield per hectare by variety and field, input cost per unit of output, labour efficiency, crop performance benchmarking across farms or seasons.

How we think about agritech.

Agricultural software has two user populations: the office user who needs dashboards and reports, and the field user who needs something that works with one hand, in sunlight, without connectivity. Design for both.

  • Offline-first is a requirement, not a feature

    Connectivity in agricultural settings is unreliable. An offline-first architecture assumes the device is offline by default and syncs opportunistically. SQLite on device, background sync with conflict resolution, and UI that never shows "connecting..." or blocks user actions on connectivity are the minimum bar for field software.

    Axiom:

  • Satellite data has changed crop monitoring

    Sentinel-2 provides free 10m resolution multispectral imagery globally every 5-10 days. NDVI (Normalized Difference Vegetation Index) from satellite data shows crop health patterns across entire fields without requiring ground sensors. Building crop monitoring without satellite imagery integration in 2024 is ignoring a free, high-quality data source.

    Axiom:

  • Farmer UX must be designed for the field

    Farmers using software in the field are wearing gloves, working with one hand, and looking at screens in direct sunlight. Touch targets must be large, contrast must be high, form fields must be minimal, and the most common action must be the easiest to perform. Lab-tested UI designed for a desktop browser is not field software.

    Axiom:

  • Traceability data quality requires capture at source

    Traceability systems that require retrospective data entry produce inaccurate records. Traceability data — what was applied, when, to which field, by whom — must be captured at the point of activity, by the person doing it. This requires mobile-first capture with minimal friction and incentives for accurate recording.

    Axiom:

Agritech platform decisions.

  • Mobile platform?

    Impact: React Native for most agritech field apps — one codebase for iOS and Android, strong offline capabilities via SQLite/MMKV, device API access (camera, GPS, Bluetooth for sensors).

    • React Native (iOS + Android) — one codebase, offline capable, most agritech teams use this
    • Flutter — alternative cross-platform, good offline support
    • Progressive Web App — no install required, limited offline and device API access
    • Native iOS + Android — best performance, double development cost
  • Offline sync architecture?

    Impact: Custom merge logic per data type is most practical: most agritech data has clear ownership (field observation by this worker on this day), making last-write-wins acceptable with field-level locking.

    • CRDTs (conflict-free data types) — most robust for concurrent edits, complex
    • Last-write-wins — simplest, data loss risk on conflicts
    • Operational transformation — complex, used in collaborative editors
    • Custom merge logic — per-data-type conflict resolution
  • Satellite imagery source?

    Impact: Sentinel-2 for most agritech platforms — free, global coverage, sufficient resolution for field-level crop health monitoring. Planet for applications requiring daily updates. Custom drone for very high resolution needs.

    • Sentinel-2 (ESA) — free, 10m resolution, 5-10 day revisit, good for most use cases
    • Planet — daily imagery, commercial, 3-5m resolution
    • Maxar — very high resolution (30cm), expensive, for specific applications
    • Custom drone — ground-level detail, operator required, not scalable
  • IoT connectivity?

    Impact: LoRaWAN for fixed sensor networks (soil, weather) — low power, long range, self-managed gateway. Cellular for equipment tracking and high-bandwidth requirements. Satellite IoT for very remote areas without LoRaWAN coverage.

    • LoRaWAN — long range (10-15km), low power, low data rate, suitable for sensors
    • NB-IoT — cellular coverage, better for moving assets, higher cost
    • Cellular (4G/5G) — high bandwidth, standard mobile coverage, highest power
    • Satellite IoT (Starlink, Iridium) — global coverage, expensive, for remote areas
  • Traceability: blockchain vs database?

    Impact: Immutable append-only database for most agritech traceability — sufficient for regulatory requirements (GAP, GlobalG.A.P, FSMA) without blockchain complexity. Public blockchain only when cross-organisation trustless verification is genuinely required.

    • Public blockchain — tamper-proof, complex, gas costs, not necessary for most
    • Private blockchain (Hyperledger) — shared immutability, complex to operate
    • Immutable database (append-only) — simpler, sufficient trust for most supply chains
    • Standard database with audit trail — simplest, acceptable for internal traceability
  • Analytics deployment?

    Impact: Embedded charts for operational dashboards, Metabase for ad-hoc reporting and management dashboards. AI-generated narrative insights are high-value for farmers who want "what should I do?" rather than raw data.

    • Embedded charts in app — simplest, limited customisation
    • Self-service BI (Metabase, Tableau) — flexible reporting, separate tool
    • Custom dashboards — full design control, higher engineering cost
    • AI-generated insights — narrative summaries from data

Agritech security for farm and supply chain data.

  • Data ownership

    Farm data belongs to the farmer. Privacy policies must be clear about data usage, sharing with third parties (input suppliers, lenders) requires explicit consent, and farmers must be able to export and delete their data.

  • Offline device security

    Mobile devices used in the field may be lost or shared. Device-level PIN/biometric lock, encrypted local database, remote wipe capability.

  • IoT device security

    Field sensors are physically accessible and may be tampered with. Device authentication, encrypted data transmission, anomaly detection for unusual sensor readings.

  • Supply chain data integrity

    Traceability data must be tamper-evident. Append-only records, audit trail for all modifications, digital signatures for key events (harvest, certification).

  • API security for integrations

    Integrations with equipment manufacturers, retailers and certification bodies require proper API authentication, scoped access and audit logging.

  • GDPR for farm worker data

    Labour management data (worker records, hours, location) is personal data subject to GDPR. Consent, access controls and retention limits required.

Frequently Asked Questions

How do we handle offline sync conflicts?

Most agritech data has natural ownership that prevents conflicts: one field observation per worker per field per day, one harvest record per field per date. Conflict prevention via data ownership rules eliminates most merge scenarios. For the remaining cases: last-write-wins with a conflict log is practical. True CRDTs are overkill for most agritech data models.

What is NDVI and why does it matter?

NDVI (Normalized Difference Vegetation Index) is calculated from near-infrared and red light bands in satellite imagery. Healthy vegetation absorbs red light and reflects near-infrared; stressed vegetation does not. NDVI values range from -1 to 1 — values above 0.3 indicate healthy vegetation. NDVI maps from Sentinel-2 satellite data show field-level crop health patterns, identifying problem areas before they are visible to the naked eye.

How does supply chain traceability work practically?

A practical farm-to-shelf traceability system works as follows: field harvest is recorded in the mobile app (crop, field, date, quantity, lot number). Each lot gets a unique ID and QR code. At each subsequent step (packing, cold storage, transport, retail), the QR is scanned and the step is recorded. A consumer or retailer scanning the final product QR sees the complete chain. Blockchain adds tamper-resistance; a well-designed append-only database provides sufficient integrity for most food safety regulatory requirements.
