Drones in Agriculture and farming

It would have been a dream of the farmer to monitor the cultivation land sitting in a place once he puts in his efforts to have a healthy crop. The dream has come true and he has now drones to help him. Drones help him not only to monitor but also to spray the pesticides all over the land in minutes. With this wonderful tool, the farmer will be able to save time, energy and money as well.

Let’s look into the benefits.

Farmer will be able to save the time as he does not need to walk around the field. This saves the energy as well.

Drones can provide the accurate picture of the crops and help the farmer to identify the area if there is any damage to the crop.

With the efficient spraying of pesticides all over the cultivation land, the farmer will save the money of the labor charges as the work will be done within minutes and there is no need to monitor the work by standing behind.

Monitoring the field by walking around costs time and energy and the farmer may not be able to cover the entire land by walking. With this, he might miss out the area where there might be damage to the crop. Thus he may not be able to control the damage. With drones, he will be able to handle this efficiently and he can monitor the land as frequently as he wants.
Now let’s look into how the drones can help.

All the above-mentioned benefits could be availed by the farmer with the use of right motor, propellers and the electronics. The selection of each part is a scientific and mathematical process. The drone can be efficient with the balanced propellers and with the brushless multi rotor motors. This will give the great flight efficiency and battery life. The right length, pitch, and speed of the propellers are the key to help the farmers.

Drones help in;

Soil and field analysis

Drones produce 3-D maps for the soil analysis. This helps in planning and planting patterns. Once the planting is done, drones provide the data for irrigation and help to manage the nitrogen level.


Planting with drone provides the plant all the necessary nutrients to have the healthy crop.

Crop spraying

Drones can scan the ground and spray the correct amount of liquid which is five times faster compared to the regular spraying by manual labor. Modulating distance from the ground and spraying in real time for even coverage. This also avoids the chemicals getting into the ground water.

Crop monitoring

This is the most important feature as the farmer can monitor the entire land by sitting in a place. There is no obstacle of the weather.


The hyperspectral, multispectral or thermal sensors of the drone help to identify which parts of a field are dry or need improvements. Once the crop is growing, the drones describe the relative density and health of the crop. They also show the amount of energy or heat which will be emitted by the crop.

Health assessment

The crop which is growing might get affected by spot bacteria or fungal infections. Drones scan a crop using both visible and near-infrared light. This gives multispectral images and helps in identifying the affected plants. This can alert the farmer to take the immediate action to reduce or stop the loss.

With the vast improvements that the technology is providing, farmers are also benefited. The cost might be the only thing that might be stopping the former in adopting them. May be the Government can be a helping hand to make the drones available for the farmers.
