BharatNotes What is Precision Agriculture?
Precision agriculture is a management strategy that gathers, processes and analyses spatial and temporal field data to guide site-specific decisions, so that inputs are matched precisely to crop needs. Instead of treating a whole field as uniform, it recognises variability within the field — in soil moisture, nutrients, pest pressure and yield potential — and responds with targeted action. The aim is higher productivity, lower input cost, and reduced environmental footprint.
Key Enabling Technologies
| Technology | Role in the field |
|---|---|
| GPS / GNSS | Accurate field mapping, auto-steer tractors, laser land levelling |
| GIS | Spatial analysis of soil, topography and yield data |
| Remote sensing & drones | Aerial imaging to detect crop stress, pest infestation, water deficit |
| IoT sensors | Real-time readings of soil moisture, nutrients, micro-climate |
| AI / data analytics | Decision support, variable-rate input prescriptions, yield prediction |
In India, application is regionally varied — laser levellers and GPS-guided machinery in Punjab and Haryana; drone-based spraying for horticulture in Maharashtra, Karnataka and Tamil Nadu; and IoT-linked drip irrigation in Andhra Pradesh and Telangana.
Government Push in India
Precision farming sits at the centre of India's digital-agriculture policy:
- Digital Agriculture Mission — approved by the Union Cabinet in September 2024 with a total outlay of ₹2,817 crore (central share ₹1,940 crore). It builds Digital Public Infrastructure (AgriStack — Farmers' Registry, geo-referenced village maps, Crop Sown Registry), the Krishi Decision Support System, and the Digital General Crop Estimation Survey (DGCES).
- Namo Drone Didi — Central Sector Scheme with an outlay of ₹1,261 crore to provide drones to 14,500 women Self-Help Groups for rental spraying services, with 80% central assistance up to ₹8 lakh per drone (period 2024-25 to 2025-26).
- Sub-Mission on Agricultural Mechanisation (SMAM) — 50% subsidy (up to ₹5 lakh) for individual small, marginal and women farmers to buy agri-drones; 100% assistance to ICAR institutes, KVKs and State Agricultural Universities for on-field demonstrations.
ICAR-led demonstrations covered 41,010 hectares and benefited 4,52,291 farmers between 2023-24 and 2025-26 (as on 30 November 2025).
Significance and Challenges
Precision agriculture raises input-use efficiency, conserves water and soil, cuts chemical overuse, and supports the goal of higher and more stable farmer incomes — directly relevant to climate-smart, sustainable agriculture. However, fragmented and small landholdings, high upfront cost of equipment, low digital literacy, weak rural connectivity and data-privacy concerns over AgriStack constrain large-scale adoption. The policy answer has been subsidies, drones-as-a-service through SHGs and FPOs, and shared digital infrastructure to spread benefits beyond large farmers.
UPSC Angle
For GS3, frame precision agriculture as a tool that connects technology, farmer welfare and sustainability. Strong answers pair concrete schemes (Digital Agriculture Mission, AgriStack, Namo Drone Didi) with a balanced critique of affordability and the digital divide, and link it to allied themes — doubling farmers' income, resource-use efficiency and climate-resilient agriculture.
