The Science
How Spectral Soil Testing Works
Near-infrared spectroscopy reads the molecular fingerprint of soil — delivering 200+ parameters in a single, non-destructive scan.
From sample to insight in 4 hours
Sample Collection
Soil cores are collected at defined depths (0–30cm, 30–60cm, 60–90cm) across the field grid. GPS-tagged for spatial mapping.
NIR Spectral Scan
Each sample is scanned across the 700–2500nm wavelength range. The spectrometer captures a unique reflectance signature for every molecular bond present in the soil.
Chemometric Modelling
Our proprietary AI models — trained on thousands of Indian soil samples — translate spectral reflectance data into quantified soil parameters.
Actionable Report
A structured report maps nutrient levels, organic matter, moisture, pH, and micronutrients — with crop-specific recommendations and field-level spatial analysis.
Spectral vs. conventional testing
The difference isn't incremental — it's structural.
| Parameter | Spectral (RURSAT) | Conventional Lab |
|---|---|---|
| Parameters measured | 200+ | 10–15 |
| Turnaround time | 4 hours | 2–3 weeks |
| Sample destruction | None (non-destructive) | Sample consumed |
| Spatial resolution | Field-grid level | Bulk average |
| Micronutrient detection | Full spectrum (Fe, Mn, Zn, Cu, B) | Limited (Fe, Mn only) |
| Organic matter accuracy | ±0.1% precision | ±0.5–1.0% precision |
| Moisture content | Real-time, in-situ | Not measured |
| Re-analysis capability | Yes — archived samples | No |
