"We can now predict with 89% accuracy whether a farmer's crop will fail — six weeks before harvest. What we do with that prediction matters just as much as the prediction itself."
— Priya Joshi, CTO, Krishi AI
When Sunita Devi's wheat field in Punjab started showing subtle discolouration in October 2025, she almost ignored it. The leaves were slightly paler than usual, but not enough to worry her experienced eye. It was only when her Krishi Box device buzzed with a warning — "High probability of nitrogen stress leading to 40% yield loss in 6 weeks" — that she took action.
She applied a targeted nitrogen top-dressing the next day. Six weeks later, her neighbors who hadn't received the warning lost an average of 35% of their yield. Sunita's loss? Under 3%.
The Science Behind the Prediction
Our crop failure prediction engine, codenamed AgraSense v3, is an ensemble of four machine learning models working in concert: a gradient boosting model trained on historical yield data, a convolutional neural network analysing satellite multispectral imagery, a recurrent neural network processing IoT time-series sensor data, and a random forest model incorporating hyperlocal weather patterns.
The key insight our research team discovered is that crop stress signals appear in soil chemistry data well before they manifest visually. By the time a farmer can see a problem, the yield impact is already partially locked in. Our models can detect these sub-visual signals from NPK imbalances, moisture variance, and temperature stress up to six weeks earlier.
What the Data Shows
Across our 2024–2025 rabi season trial involving 847 farms across six states, AgraSense v3 issued 2,340 early warning alerts. Independent agronomists validated outcomes post-harvest:
- 89.2% of predicted high-risk events resulted in measurable yield stress
- Farmers who acted on warnings within 72 hours recovered 78% of predicted losses
- Average yield protection value: ₹14,200 per farm
- False positive rate: 8.4% (farmers received alerts but crops were fine)
How Farmers Are Using the Warnings
The alerts arrive as WhatsApp messages in the farmer's regional language, with simple instructions: "Your soil nitrogen is 18% below optimum. Apply urea at 25kg/acre before Saturday for best results." No complex agronomic jargon, no requirement for literacy — the message is simple, actionable, and timely.
"I didn't know what nitrogen deficiency even was before Krishi AI. Now I understand my soil like a doctor understands a patient."

What's Coming Next
Our research team is currently training AgraSense v4 with two new data streams: drone imagery for individual plant-level analysis, and a network of 50,000 weather micro-stations being deployed across key agricultural districts. Our target is to improve prediction accuracy to 94% and extend the warning window to 8 weeks by the 2026 kharif season.
We're also developing a cooperative early-warning system that anonymously pools data from nearby farms, allowing earlier detection of region-wide pest pressures and disease outbreaks before they spread.
Precision agriculture has long been a luxury of large commercial farms. At Krishi AI, we believe it's a right of every Indian farmer — and the technology is finally ready to deliver on that promise.
