Precision Agriculture: A farming management concept based on observing, measuring and responding to inter and intra-field variability in crops using technology.
VarshaKrishi makes precision agriculture financially accessible to Indian farmers through a ₹60,000 one-time hardware investment, eliminating recurring SIM costs via solar-powered LoRa telemetry.
Precision agriculture replaces uniform, calendar-based farming with site-specific management: measure what each zone of a field actually needs — water, nutrients, protection — and apply exactly that. The toolchain spans soil and microclimate sensors, satellite imagery (NDVI/EVI vegetation indices), positioning, and decision models that turn measurements into actions.
The economics work even at smallholder scale when the sensing is cheap enough: water savings of 30-45%, fertiliser placed where soil tests show deficits rather than broadcast evenly, and disease sprays timed to actual infection windows instead of prophylactic rounds. Studies from ICAR and IWMI pilots consistently show payback within one to three seasons.
VarshaKrishi packages precision agriculture for Indian conditions on two tracks: offline LoRa sensor networks for ground truth, and a satellite crop-advisory platform that converts free Sentinel-2 imagery into per-field vegetation health and plain-language advisories in 8 Indian languages.
Yes, when costs are shared: a village-level gateway serving clustered smallholder plots brings per-farm hardware costs down dramatically, and satellite-based advisories need no hardware at all. The margin gains that matter most — water, power and spray savings — scale down to one-acre plots.
Four layers: soil data (moisture, pH, nutrients), microclimate data (temperature, humidity, leaf wetness), crop observation (satellite vegetation indices, scouting) and agronomic models that convert those into irrigation, nutrition and protection decisions.
