SLM, RAG, Pipelines, Knowledge Graphs, Vector DB & Quantum Signal Wave Analysis
End-to-end inspection of how raw sensor packets become a single sentence on a farmer's phone — with an in-browser small language model, retrieval index, agronomy graph, and quantum-style waveform decomposition of crop health signals.

0.391PestPink bollworm pheromone trap catches > 8/night combined with NDVI dip > 0.06 in 5 days suggests early infestation in cotton bolls.
0.352IrrigationFor black cotton soils in Maharashtra, irrigate cotton when capacitive moisture at 25cm falls below 28% VWC. Avoid irrigation if rain probability > 60% in next 24h.
0.258MarketPune APMC cotton spot price tends to rise 4.2% in 10 days after rainfall deficit > 30mm vs LPA in flowering window.
0.214Soil HealthDS18B20 soil temp above 34°C at 10cm slows microbial nitrogen mineralisation. Mulch with 4cm sugarcane trash to drop temp 3–5°C.
0.151FertigationEC above 2.4 mS/cm at root zone indicates salt stress. Flush with 8mm clean water and pause urea-based fertigation for 48 hours.
