Agriculture 4.0 is redefining the role of the Indian farmer, from labour-intensive worker to data-enabled decision-maker. The technologies listed above are not futuristic experiments, but are available today and already delivering results. With the right partners, tools, and training, smart farming can become the new normal across India’s croplands.
What Farming Techniques Define Agriculture 4.0?
The shift to Agriculture 4.0 is strategic, enabling farmers to move from blanket practices to highly targeted interventions. This results in higher efficiency, lower waste, and greater profitability per acre.
This transformation is being driven by a set of practical, farmer-friendly techniques that combine science, software, and on-the-ground expertise.
Here are the key practices that form the backbone of Agriculture 4.0 and how they’re being applied in Indian fields today:
Precision Farming
This technique focuses on applying the right input, in the right quantity, at the right location and time.
GPS-guided drones and AI-backed systems reduce wastage by spraying only where needed.
With Leher’s drone services, farmers can adjust spray volume based on field contours, crop density, and type, maximising impact and saving input costs.
Data-Driven Decision Making
Farming decisions are no longer based on gut feel. Real-time data, visualised in dashboards, empowers action with clarity.
Leher’s Spray Management System offers insights into chemical use, field coverage, drone battery levels, and cost per acre.
These insights help farmers and operators make timely, cost-effective decisions.
Remote Field Monitoring
With IoT sensors, satellite feeds, and app-based alerts, farmers no longer need to be physically present to manage operations.
Field conditions such as soil moisture, pest incidence, and crop health can be tracked remotely.
This is especially powerful for large landowners, contract farming groups, and input companies working across geographies.
Variable Rate Application (VRA)
VRA ensures that inputs like fertilisers and pesticides are applied in variable doses across the field, depending on actual need.
Instead of spraying the entire plot uniformly, the system adjusts dosage based on zone-specific data.
Leher’s drones are VRA-ready, helping reduce chemical use and ensuring compliance with crop-specific standards.
Geo-tagged Spraying & Traceability
In Agriculture 4.0, every action can be logged, tracked, and verified.
Leher offers geo-tagged spray reports that show exactly where, when, and how much input was applied.
This traceability supports better compliance for exporters, FPOs, and agri-enterprises.
Why These Techniques Matter?
In a country where 47% of the population depends on agriculture, but margins are shrinking, adopting these smart techniques is essential. With tools like Leher’s drone services and digital dashboards, even small and mid-sized farms can access the benefits of high-tech precision without heavy investment or training.
Agriculture 4.0 techniques turn uncertainty into opportunity. By reducing input waste, improving crop outcomes, and enabling real-time control, these methods pave the way for sustainable and profitable farming.

What Are the Benefits of Agriculture 4.0 for Indian Farmers?
Agriculture 4.0 introduces scalable, real-world benefits that save time, reduce costs, and increase profitability. Here’s how farmers are experiencing these changes on the ground:
Spray More in Less Time
Traditional spraying methods are slow and often inconsistent, especially across large or uneven fields. With drone services like Leher’s, farmers can now cover up to 50 acres in a single day.
Tasks that used to take four hours can now be completed in minutes. This will enable farmers to act quickly during weather-sensitive spray windows, improving the overall timeliness of their operations.
Save on Pesticides and Fertilisers
Over-application of agrochemicals not only wastes money but also harms soil and crop health. Agriculture 4.0 tools, such as variable rate spraying, ensure that pesticides and fertilisers are applied only where needed.
Leher’s precision drones help farmers cut chemical use by up to 30%, making every litre count without compromising crop protection.
Protect Worker Health
Manual spraying exposes farmers and workers to harmful chemical fumes. Drone spraying removes the need for close contact entirely. Operators remain at a safe distance while drones handle the task, significantly lowering the risk of respiratory and skin-related issues, especially in regions where protective gear is limited or rarely used.
Boost Crop Yields
When inputs are applied more accurately, crops respond better. Uniform coverage ensures that each plant receives the right dose at the right time, improving nutrient uptake and disease resistance. This leads to an increase in crop yield depending on the crop, helping farmers get more from the same land with fewer inputs.
Conserve Water Efficiently
In a country where agriculture consumes over 80% of freshwater, saving water is no longer optional. Drone-enabled foliar sprays and sensor-driven irrigation techniques reduce water use dramatically, by up to 90% compared to traditional flood irrigation. These methods are especially beneficial in drought-prone areas or for water-intensive crops, such as sugarcane and paddy.
