Agriculture is India's largest industry, accounting for almost 75 percent of the country's GDP through farming and other agricultural services. With the improvement of technology and instruments, agriculture has experienced a boom. Tractors and, more recently, other machinery have replaced animal sowing. Crop cutting is no longer a labor-intensive task.

Technology has shown to be the magic boon for the agriculture industry in similar ways. The government has declared the sector's digital development, which will allow digital start-ups to intervene and revolutionize the industry.

Remote Sensing and Internet of Things

Farmers and other stakeholders may make management decisions based on landscape-level statistics that include soil type, water table depth, land cover, resource usage, ecosystem data, pest and disease data, and weather using remote sensing technologies. While this information can originate from sensors on the ground or satellites, there is growing potential to employ unmanned aerial vehicles (UAVs) or drones to monitor local land usage and gather satellite data in real-time utilizing the Internet of Things (IoT).

3D printers

3D printers have the potential to revolutionize agriculture in India if they are implemented. Farmers will be able to create critical farming chemicals such as herbicides, insecticides, and veterinary medications on their own farms using this technology. It won't take up any more time because it can be made anywhere, at any time. Three key components are required for 3D printing: a software app, a 3D printer, and chemical inks. In India, the technology is currently unavailable. However, if this low-cost technology makes its way to India, it has the potential to revolutionize agriculture.

Hydroponics

Even in metropolitan locations, the combination of two technologies may generate food in a sustainable manner. The technology incorporates hydroponics, or the practice of growing plants in water without the need for soil, as well as fish farming. Given the growth in population, it is estimated that by 2050, more than 70% of the land would be urbanized. In these situations, the world requires an alternative to traditional agriculture. Aquaponics is one such option. It's a circular system that not only delivers nutrients to plant roots via water but also generates a system that uses less water and energy.

Hyperspectral imaging sensor

In impoverished nations, a new low-cost hyperspectral imaging sensor for cellphones might make it simple to identify agricultural illnesses early and reduce crop losses dramatically. This technology can be used to scan plants for illness signals, which can then be matched to databases of suspected diseases and actions recommended. Scalers may add new illnesses to the database as they are identified, allowing the database to grow and provide an early warning system.

Signaling plants

Sentinel plants, also known as signaling plants, are used in agriculture systems to detect biotic and abiotic stress. They give early warning signs of crop stress, such as leaf color changes. Emerging pests and illnesses, nutritional deficits, and changes in soil conditions can all be detected early by these plants.
