Digital platform connecting field-level soil testing kits to lab analysis
A platform for a national research body's soil testing programme — capturing field data from portable testing kits, routing samples to labs, aggregating results, and generating farmer-readable soil health reports with pH correction advisories and fertility recommendations.
The Challenge
A national research body runs a large-scale soil testing programme to help farmers understand their soil health and optimize fertilizer application. Field workers collect soil samples using portable testing kits, samples are sent to labs for detailed analysis, and results need to reach farmers in an understandable format with actionable recommendations.
The existing process was paper-based at every step. Field data was recorded on forms, manually entered into spreadsheets, and sent via email to labs. Lab results came back as PDF reports that had to be re-entered for farmer report generation. Data entry errors compounded at each step. The time from sample collection to farmer advisory was measured in weeks.
The programme needed a digital pipeline that connected field collection directly to lab routing, automated result aggregation, and generated farmer-readable reports with localized recommendations — all while maintaining data quality and audit trails.
Our Approach
We mapped the entire workflow from field to farmer, identifying every data handoff point. The key insight was that most delays weren't in the lab analysis itself — they were in the manual data entry steps before and after. Eliminating these handoffs would dramatically accelerate the pipeline.
The field app needed to work offline — rural areas often lack connectivity. We designed it to capture data locally with automatic sync when connectivity returns. QR codes on sample bags link physical samples to digital records, ensuring traceability.
The farmer-facing reports required careful design. Most farmers aren't comfortable with technical soil science terminology. We worked with agronomists to translate pH values, nutrient levels, and microbial counts into simple traffic-light indicators and plain-language recommendations: 'Your soil needs lime application before the next planting season.'
What We Built
Field Data Capture
Mobile app for field workers to record sample collection. Works offline with automatic sync. GPS tagging of collection locations. QR code scanning to link physical samples to digital records.
Lab Routing & Tracking
Automatic routing of samples to appropriate labs based on location and test requirements. Sample status tracking from collection through analysis. Lab result entry interface with validation.
Result Aggregation
Centralized database of all soil test results. Historical tracking for repeat samples. Regional aggregation for programme-level insights. Data quality checks and anomaly detection.
Farmer Reports
Auto-generated soil health reports in farmer-friendly format. Traffic-light indicators for key parameters. Plain-language recommendations for pH correction, fertilizer application, and organic matter management.
Advisory Engine
Crop-specific recommendations based on soil test results. pH correction advisories with lime/gypsum calculations. Fertilizer recommendations optimized for target yields. Localized advice based on regional conditions.
The Outcome
The digital soil testing platform eliminated paper-based delays throughout the field-to-farmer pipeline. Sample tracking is now real-time. Lab results flow directly into report generation. Farmers receive actionable soil health reports within days rather than weeks of sample collection.
