Global data sources —
where NAITRO's numbers come from.

Every score, threshold and recommendation on this platform traces back to a named source. This page lists the datasets, APIs and frameworks NAITRO draws on — what's live and queryable today, and what's used as a reference framework.

Live soil data APIs

iSDA Africa
innovative Solutions for Decision Agriculture
Live API
Continent-wide, 30m-resolution machine-learning soil property service covering ~30 properties per coordinate (pH, N, P, K, CEC, texture, carbon) with depth stratification and uncertainty bounds. Queried for SA1, SA2, and SA3.

Wageningen University Research, with Rabobank, a.s.r., Vitens
Reference
21-indicator open-source soil quality scoring framework across Chemical, Physical, Biological, and Management domains. The architecture NAITRO's farm-level Soil Health Score is adapted from for NZ and SA conditions.

NPS-FM 2020 / Overseer
NZ Ministry for the Environment
Reference
New Zealand's freshwater nutrient compliance regulation. OverseerFM, the prior modelling tool used to assess compliance, was found "not fit for purpose" by the Office of the Chief Science Advisor in 2021 — the regulatory gap NAITRO's IoT-verified scoring is designed to fill.
