Agriculture Drone – Everything You Need To Know

Drones have many applications. But one of the best and worthwhile applications of these mini- aero planes lies in the field of agriculture. We are living in a time when ensuring food security has become a global challenge and managing whatever little natural resource that we have to deal with the challenge has become our topmost priority. Introducing Unmanned Aerial Vehicles (UAV) to help our farmers do just the right thing at the right time is perhaps the least we can do to help the world become more efficient.  

What is an Agriculture Drone?

An agriculture drone is a specialized type of Unmanned Aerial Vehicle equipped with sensors and digital imaging capabilities, specifically used for the purpose of agricultural optimization. An agriculture drone allows farmers to monitor their crop fields from a different angle, making it easier to identify issues such as irrigation problems, soil variation, and pest and fungal infestations. The aerial view of crop fields that these UAVs can provide is much more reliable when it comes to gathering information about crop health than taking for granted what only human eyes can see.

Drone Farming and Benefits

Farming has always been a resource and labor-intensivetask for centuries. Therefore, it should not come as a surprise that farmers will eventually be driven towards the adoption of technology in order to improve efficiency. The overall consumption of food products in recent decades has risen to all-time high and so has the production of crops worldwide. This means that the use of pesticides in lands has increased, soil conditions have deteriorated and as a result, the quality of the food products that we consume has significantly declined. The resource we have is limited, but there are a plethora of challenges to be met. And that is where the concept of drone farming comes in.

The biggest barrier to achieving higher efficiency for the farmers is their inability to access vital information about their crops at the right time, at a lower cost. The majority of farmers do not know which particular pest plagues their crop fields, which pesticides to use to get rid of it and what amount of pesticide should they be using to keep the soil still fertile for the next season. As a result, they rely on guesswork and end up wasting too much resources.

Agriculture Spraying Drone

The usefulness of drones in driving up efficiency by solving these problems is unparalleled. By using drones, farmers can wave goodbye to all the guesswork they have been doing for centuries. It is true however that the farmers do not have any control over the weather or temperature surrounding their lands, but the primary key solution here is to gain the ability to adjust, the ability to extract information at just the right time so that they can take instantaneous decisions at any given situation.

Drones can offer a pool of information regarding the outbreak of certain crop diseases, the area of infection, the possible spread region, and the soil condition. By gaining access to this pool of information in real-time, farmers can choose the types of pesticides they need and calculate the amount they need. Thus, saving a significant amount of time and resource on farming.

Use of Drones in Agriculture

Enabling the farmers to make decisions with unparalleled accuracy and precision is not all that an agricultural drone can offer. There are a number of other benefits of drone farming which needs to be discussed here too.

Monitoring Plant Health

Many farmers around the world rely on satellite imagery to monitor plant health. But the cost of gaining access to satellite data is not something that many farmers in developing countries may find convenient. Moreover, satellite data can become distorted due to poor light conditions and cloud cover, rendering inaccurate information about crop health which would be of little or no use to the farmers.

Drones usually fly closer to the ground, meaning that they can provide more accurate data about plant’s health even in low light conditions and you don’t even have to consider cloud cover as a barrier.  UAVs equipped with specialized imaging equipment called Normalized Difference Vegetation Index (NDVI) have gained much popularity nowadays due to their ability to use color information to indicate plant health. By using such drones, farmers can identify issues more accurately as their plants grow and react almost instantly to save their plants.

Gathering Information About Field Condition

The most important prerequisite for growing crops is to know about the field /land which will be used for harvesting. Drones can be used for field mapping which can provide farmers with enough information about the field condition. Information such as field elevation, irregularities, nitrogen level can be easily determined only by equipping the drone with specialized sensors. These information can further help the farmers to determine drainage patterns and choose suitable fertilizer for their field.

Planting Trees and Sowing Seeds

Planting trees with using drones is much more efficient and safer. Farmers can use drones to plant trees and spread seeds in remote locations without having to endanger human workers. Using drones for plantation purposes is widespread nowadays in the forestry industry. Farmers too can gain a lot more from this in near future.

Spraying Pesticides

Traditional spraying techniques require a human worker to carry a backpack. Carrying sprays is not only hazardous to their health but also laborious because spraying involves navigating through remote areas across the field. It becomes even harder in high elevation areas and steep grounds like tea gardens. Using drones in such areas can increase spraying efficiency by more than 20%. In addition to that, using drone sprayers can help the farmers in reducing the cost of chemicals.

Types of Agriculture Drone

Drones are available in the market in all sizes and shapes. But you need to buy the one that suits your purpose. For the purpose of farming, drones are mainly available in two major body types –

Fixed Wing

As the name suggests, these drones have a pair of fixed wings and a single rotor. They are almost similar to a modern aircraft in design. Fixed-wing drones have gained more popularity among farmers due to their ability to cover a long distance during a single flight. The average flight duration of a fixed-wing drone is about 1 hour and can cover up to 200 to 300 acres during this time. They are faster, capable of flying at higher altitudes, and can carry more loads than the other type of drone.

Multi Rotor

Multi-rotor drones are the most common type of commercial UAVs in the market. These drones consist of a central chassis and a couple of propellers to control the speed and maintaining balance during flight. Based on the number of propellers, they can be classified into several other categories such as troopers (3 propellers), quadcopters (4 rotors), hex copters (6 rotors), and octocopters (8 rotors). These propellers or rotors offer the drone an enhanced degree of precision while operating. Multi-rotors are cheaper and easy to manufacture compared to fixed-wing drones.

While the multi-rotors allow for better control, they are not as fast as fixed-wing drones. Multi-rotor UAVs also lag in flight range, duration, and payload capacity compared to fixed-wing drones.
