# ISRO study maps Andhra soil health with satellite AI 2026-08-09T01:56:20+00:00 | Governance | Indian Opinion Desk Corroboration: 1 independent outlet An ISRO-National Remote Sensing Centre (NRSC) study has used satellite imagery and machine learning to map soil health in Andhra Pradesh's Indukurpet mandal. The researchers combined Landsat-8 data with 175 field samples to predict soil pH and salinity, producing digital maps that highlight small patches often missed by traditional sampling. The study, published online in Environmental Earth Sciences on June 15, 2026, found that Random Forest and Gradient Boosting Regression were the most accurate models. The method offers a cost-effective way to guide targeted soil testing and fertiliser decisions, especially for salinity-sensitive crops like paddy. ## Coverage - timesofindia.indiatimes.com Tags: agriculture, Andhra Pradesh, ISRO, machine learning, NRSC, soil health Canonical: https://indianopinion.org/isro-study-maps-andhra-soil-health-with-satellite-ai/ License: Summary and commentary (c) Indian Opinion, reusable with attribution.
