India's use of drones for agriculture

India's economy is largely based on agriculture. For the vast majority of rural households, agriculture continues to be their main source of income. A significant amount of India's exports are agricultural products, which are another important component of its economy. Despite the growing importance of agriculture, the industry is still lagging behind in terms of technical development. The main causes of this situation have been crop failure owing to unfavorable weather and unmanaged pest problems. Indian farmers still use conventional methods for other elements of farming and rely on the monsoon rains for irrigation. Thus, despite farmers' tireless efforts, the quality and quantity of agricultural produce is occasionally affected.
Thankfully, there is yet hope. What if crop failure could be predicted beforehand, allowing for the appropriate action to be taken? Can conventional farming practises and cutting-edge approaches like agri-drones coexist to solve the issues plaguing India's agricultural sector? Can drones play a significant role in agricultural observation, improving the possibilities of failure mitigation? In this post, we'll examine each of these possibilities in an effort to predict what the future may hold.

The use of drones in Indian agriculture
Unmanned aerial vehicles or drones, are utilized for surveillance across a variety of businesses. Up until recently, they were mostly utilized by businesses in the mining and construction industries, the military, and amateurs.
But now that drone technology is more widely accessible, it may also be used in a number of agricultural areas. Though the technology is still in its infancy in India, numerous businesses are working to make it freely accessible to Indian farmers and prepared for use to boost agricultural production efficiency.

There is an Increase in the Use of Agri-Drones
In India, there are numerous drone-based agricultural projects in progress. Consider the following examples from your daily life:

• The Government of India also announced a certification programme for agricultural drones on January 26, 2022. These drones are now permitted to carry a payload devoid of any chemicals or other liquids used in drone spraying. When spraying these solutions, make sure to abide by all rules and regulations.
• The Indian government recently offered the Farm Machinery Training and Testing Institutes, ICAR Institutes, Krishi Vigyan Kendras, and State Agriculture Universities a 100% subsidy up to March 2023, whichever is less, to encourage the use of drones for agricultural purposes and decrease the labour burden on farmers.
• In addition, a reserve budget of Rs. 6000 per hectare would be established for hiring drones from specialized hiring facilities (CHC). The farmers will be able to acquire and use this sophisticated equipment at a low cost with the aid of the subsidies and the emergency funding.
• The International Crops Research Institute received permission from the Indian government to utilize drones for agricultural research on November 16, 2020. The government hopes that by taking this action, it will inspire aspiring scientists and businesspeople to consider low-cost drone solutions for the more than 6.6 lakh Indian villages.
• Even though the usage is conditional, it is nonetheless a bold step. Drones are anticipated to have a significant impact on agriculture, especially in sectors like precision agriculture, agricultural yield increase, and locust management, according to Amber Dubey, Joint Secretary, Ministry of Civil Aviation.

Benefits of Drone Use in Agriculture
Drone technology in agriculture is a permanent fixture.  Recent studies predict that by 2025, the global drone industry for agriculture would increase at a compound annual growth rate of 35.9% and reach $5.7 billion.
Drone technology in agriculture is a permanent fixture. Farmers may be able to work faster and more effectively with the aid of this new technology. Drone use in agriculture is expected to grow as the industry matures, so it is advisable to adopt responsible usage practises.

Examination of soil and fields
Drones used in agriculture can examine soil and fields to plan fields more efficiently. They can be used to mount sensors that assess soil fertility, soil nutrient concentration, soil erosivity, terrain, and soil conditions.

Crop observation
Crop surveillance is the monitoring of a crop's development from the time the seeds are sown until the crop is ready to be harvested. This includes timing the application of fertilisers, keeping an eye out for diseases and pests, and tracking the impact of weather. The only way a farmer can guarantee a timely harvest, particularly when working with seasonal crops, is through crop surveillance.
At this point, any mistakes could lead to a failed crop. The upcoming farming season can be understood and planned for with the use of crop surveillance. Drones can help with effective crop surveillance by scanning the area using infrared cameras. The health of the plants there can then be improved by farmers taking immediate action based on the information they get.

Plantation
Drones can assist in planting crops and trees, a task previously carried out by farmers. This technology will assist save on both labor costs and gasoline costs. In the near future, cost-effective drones are expected to take the place of large tractors because they harm the environment and generate hazardous chemicals.

Livestock management
Because large cattle have high-resolution infrared cameras incorporated into their sensors, which can swiftly spot sick animals and take appropriate action, they can be monitored and handled by drones. As a result, the impact of drones on precise dairy production will quickly replace the current standard.

Crop spraying
When compared to conventional methods, agri-drones can spray chemicals on crops quickly since they have reservoirs that can be replenished with fertilizers and insecticides. As a result, drone technology may bring in a new era of precision farming.

Check crop health
Agriculture is a large-scale endeavor that involves acres of land. To keep track of the condition of the soil and the crop that has been planted, regular surveys are required. If done manually, it might take days, and even then, mistakes could be made by humans. The same task can be completed by drones in a few hours. Drones can use infrared mapping to collect data on the condition of the crop and the soil.

Avoid excessive chemical use
Particularly when it comes to decreasing the overuse of herbicides, insecticides, and other chemicals, drones can be quite useful. These substances do in fact aid in crop protection. But using them excessively can be harmful. Drones are able to identify even the tiniest indicators of pest infestations and provide precise information on the intensity and territory of the attack. This can assist farmers in determining the necessary dosage of chemicals to employ so that the crops are only protected, not harmed.

Prepare for weather glitches
The weather has the potential to be both a farmer's best friend and worst enemy. It is quite challenging to get ready for any change in patterns because they cannot be precisely foreseen. Future weather conditions can be forecast using drones. Already, better forecasts are being made using storm drones. Farmers can also make better preparations by using this knowledge. The crop to be planted that would be best suited for the season, as well as how to care for planted crops at a later stage, can be planned using advance notice of storms or lack of rain.

Monitor growth
Crops need to be surveyed and monitored even when everything is going according to plan to make sure the proper yield will be available when it's time to harvest. It is also crucial for planning the future, whether it is for picking cyclical crops or figuring out the best pricing for the open market. Drones can provide accurate data on every stage of crop growth and can warn farmers of any deviations before they become a catastrophe. Furthermore, multispectral imaging can reliably spot subtle differences between healthy and unhealthy crops that the naked eye can miss.For instance, compared to healthy crops, stressed crops will reflect less near-infrared light.

Geofencing
The thermal video cameras on drones can quickly identify people or animals. Drones can thereby protect crops from animal damage, especially at night.

Advantages of agri-drones

Security
Drone pilots with the appropriate training fly the drones. Therefore, there is no possibility of misuse.

High performance
Drones operate instantly and can complete tasks twice as quickly as people.

Water-saving
Agricultural drones use ultra-low volume (ULV) spraying technology, which uses less water than conventional spraying techniques.

Low cost and simple maintain
Agri drones are reliable, inexpensive, and require little upkeep. A detachable container, a cheap frame, and precision pesticide spraying are some of the essential features.

Agri drones limitations

Connection problem
Online availability is frequently nonexistent in rural places. In such cases, a farmer will need to make an investment in internet connectivity, which might become an ongoing cost.

Based on the weather
Good weather is crucial for drone operations. Drone flight is not advised while it is raining or windy outside.

Information and ability
Although using new technology is a wonderful change, doing so frequently requires the necessary skill set and understanding. It could be challenging for the average farmer to understand how a drone operates. He must either acquire the information or keep using a professional.
