🚁 Drone Spraying of Pesticides and Fertilizers: A New Revolution in Smart Farming

Today, farming in India is becoming modern very fast. Along with traditional methods, farmers are now adopting new technologies. One of the most important technologies is drone spraying of pesticides and fertilizers.

If you want to know how drone spraying works, what is the cost, what are the advantages and disadvantages, and what are the rules in India – this complete guide is for you.

This article is written in simple Indian English so that every farmer brother and agriculture entrepreneur can easily understand it.

🚜 What is a Drone?

A drone is an Unmanned Aerial Vehicle (UAV). It is flown using a remote control or an automated system.

Drones used in agriculture are specially designed for spraying and monitoring fields.

🔹 It Includes:

• 🛢️ Tank (10–30 litres)
• 🔋 Battery system
• 📡 GPS and auto-pilot
• 🌫️ Spray nozzle
• 🎮 Controller or mobile app

⚙️ How Does an Agriculture Drone Work?

1️⃣ First, a digital map of the field is prepared.
2️⃣ Pesticide or liquid fertilizer is filled into the drone tank.
3️⃣ The drone flies at a fixed height (2–4 meters).
4️⃣ It sprays evenly according to GPS guidance.
5️⃣ When battery is low, the auto-return feature works.

👉 This ensures equal spraying across the entire field.

🐛 Drone Spraying of Pesticides

Pesticide spraying is one of the most important parts of farming. If spraying is not done on time, the whole crop can get damaged.

🎯 Advantages of Drone Pesticide Spraying

✅ 1. Time Saving

In one acre field, where traditional spraying takes 2–3 hours, a drone can finish in just 10–15 minutes.

✅ 2. Saving of Chemicals

Up to 20–30% less pesticide is used.

✅ 3. Farmer Safety

Protects farmers from direct contact with harmful chemicals.

✅ 4. Easy in Difficult Areas

Spraying is easy in water-filled fields, muddy land, and tall crops.

🌾 Drone Spraying of Fertilizers

Proper and equal distribution of fertilizer is very important for crop growth.

When liquid fertilizer is sprayed using drones:

✔️ Plants get equal nutrition
✔️ Crop growth becomes better
✔️ Production increases

📊 Variable Rate Technology (VRT)

Some modern drones use Variable Rate Technology (VRT).
This means the drone sprays more fertilizer where needed and less where not required.

📊 Drone Spray vs Traditional Spray

Comparison Point	Traditional Method	Drone Method
Time	More	Very Less
Labour	High	Low
Accuracy	Low	High
Health Risk	High	Low
Cost (Long Term)	High	Low

👉 In the long run, drone spraying is more cost-effective.

💰 What is the Price of an Agriculture Drone?

In India, the price depends on tank capacity and features.

• 🔹 10 Litre Drone: ₹3–4 lakh
• 🔹 20 Litre Drone: ₹5–7 lakh
• 🔹 30 Litre Drone: ₹7–10 lakh

🏦 Government Subsidy on Drones

The Government of India is promoting agriculture drones.

• 📌 40%–50% subsidy for farmers
• 📌 Higher benefits for FPOs and agriculture institutions
• 📌 Special support for Custom Hiring Centres

👉 Because of subsidy, even small farmers can take drone services.

📜 Drone Rules in India

In India, drone operations are controlled by the Directorate General of Civil Aviation (DGCA).

Important Requirements:

• 🔹 Drone pilot license
• 🔹 UIN registration
• 🔹 Geofencing system
• 🔹 Follow No-Fly Zones

Flying a drone without permission is illegal.

🌱 In Which Crops Are Drones Useful?

Drone spraying is useful in:

• ✔️ Paddy
• ✔️ Wheat
• ✔️ Cotton
• ✔️ Maize
• ✔️ Sugarcane
• ✔️ Soybean
• ✔️ Vegetables

👉 Drones are especially beneficial in large farms.

🚀 Main Benefits of Drone Farming

🌟 Increase in production
🌟 Reduction in cost
🌟 Less water requirement
🌟 Environmental protection
🌟 Employment opportunities for youth

👨‍💼 How to Start a Drone Business?

If you want to start a drone spraying business:

1️⃣ Take training from DGCA-approved institute
2️⃣ Purchase an agriculture drone
3️⃣ Promote your services in villages
4️⃣ Charge ₹300–600 per acre
5️⃣ Good earning possible during season

👉 With one drone, you can earn ₹1–2 lakh per month (depending on season).

📊 Possible Income from Drone Technology

If you want to start a drone service business, it can be a big opportunity.

👉 Estimated Calculation (Example)

• 20 acres per day
• ₹400 per acre
• ₹8,000 per day

If you work 20 days in one season:

• ₹8,000 × 20 days = ₹1,60,000

Even after reducing expenses, good profit is possible.

⚠️ Precautions While Using Drones

While operating a drone, you must follow some safety steps.

🔸 Important Precautions

• Do not fly in strong wind
• Keep the battery fully charged
• Mix the medicine in correct quantity
• Wear safety equipment
• Take permission from local authorities

🌍 Impact on Environment

Because drone spraying is accurate and controlled:

• 🌱 Less use of chemicals
• 🌱 Less soil and water pollution

❓ Frequently Asked Questions (FAQs)

Here are some important questions asked by farmers and agriculture entrepreneurs.

1️⃣ Can Small Farmers Also Use Drones?

✅ Yes, absolutely.

If farmers do not want to buy their own drone, they can take services from Custom Hiring Centres or private drone service providers.

Small farmers can also get benefits through government subsidy and FPO (Farmer Producer Organization).

2️⃣ How Many Acres Can Be Sprayed in One Day?

🚁 A normal 10–20 litre agriculture drone can cover:

• 4–6 acres per hour
• 20–25 acres per day (depending on battery and refill)

It also depends on crop height and field condition.

3️⃣ Is Drone Spraying Safe?

🔒 Yes, if done properly.

Important Things to Follow:

• Follow DGCA rules
• Use trained pilot
• Use correct chemical quantity
• Do not fly in strong wind

Drone spraying reduces direct contact of farmers with harmful chemicals, so health risk becomes less.

4️⃣ How Long Does Drone Battery Last?

🔋 Usually:

• 10–20 minutes per flight
• Work becomes faster if you have 2–3 batteries

Modern drones also have fast charging facility.

5️⃣ Can Drones Spray Solid (Granule) Fertilizer?

🌾 Some special models have granule spreader attachment.
But most drones are mainly used for liquid fertilizers and pesticides.

6️⃣ What is the Cost of Drone Spraying?

💰 On rent: ₹300–₹600 per acre (depends on area)
💰 Buying own drone: ₹3–10 lakh (depends on capacity)
