🛰 Satellite Monitoring (Sentinel-2)
🛰 Satellite monitoring activates from the moment your project GPS coordinates are registered. Sentinel-2 passes every 5 days. NDVI and soil index provide acidity proxy indicators — combine with IoT sensors for direct pH measurement.
🌿 NDVI (Vegetation Health)--
Healthy vegetation = better buffered pH. Low NDVI often correlates with high acidity stress.
🌎 BSI (Bare Soil Index)--
High BSI indicates exposed, degraded soil. Acidic soils suppress vegetation leaving bare patches detectable by satellite.
👋 Clay Mineral Index (SWIR)--
SWIR band ratio detects clay content and iron oxide minerals associated with laterite acidification.
🌱 Soil Organic Carbon proxy--
SOC buffers soil pH. Low organic carbon increases vulnerability to acidification from rainfall and leaching.

Months to Target pH
🌱 Based on your inputs, apply 2.4 t/ha of agricultural limestone in split applications (50% now, 50% after first rains). Incorporate to 15 cm depth by tillage. Re-test pH after 6 months.

🌿 NPK & Soil Chemistry Monitoring
🛰 Soil acidity strongly affects nutrient availability. At pH <5.5, nitrogen becomes volatile, phosphorus locks up, and aluminium/manganese reach toxic levels. Monitor NPK alongside pH for a complete soil health picture.

🪴 Engineered Biochar Amendment — Acidity Correction INNOVATIVE
Enterprise & Professional
🪴 Beyond Lime: Engineered alkaline biochars can shift soil pH by +0.5 to +2.5 units while simultaneously sequestering carbon, improving water retention, and building long-term soil structure — benefits no lime product can offer. Select a biochar type and your target pH shift to get a tailored dose recommendation.
