GPS in Agriculture: Precision Farming and the Future

Modernizing agriculture is critical to meeting the current global food demand. Precision farming is a rapidly evolving technology that will help address the issue of food scarcity. Precision farming is increasingly popular, with a projected market value of $9.53 billion by 2023. With precision farming at the forefront, farmers are now leveraging GPS technology to enhance productivity and efficiency in their operations. Global Positioning System (GPS) and GPS tracking provides new avenues of asset tracking and monitoring, allowing for precision tracking of farming tools and raw materials required to that end.

Let’s delve into the countless ways GPS is transforming modern agriculture and explore the possibilities it holds for the future in detail here.

What is GPS, and how does it work in Agriculture Sector?

GPS (Global Positioning System) uses a network of 24 satellites orbiting the Earth to provide accurate positioning information. In agriculture, GPS receivers are used to obtain location data that can be utilized in various ways to improve farming operations.

To determine the precise location of a field, GPS receivers receive signals from multiple satellites. Each GPS satellite broadcasts on at least two frequency bands: L1, 1575.42 MHz, and L2, 1227.6 MHz (newer satellites also broadcast on L5, 1176 MHz). The satellites can calculate the exact position on the earth's surface by triangulating the signals received from GPS trackers or receivers (same with smartphones). The accurate positioning data is then used in conjunction with specialized software and equipment to guide farming activities.

GPS receivers can be installed on tractors, combine harvesters, sprayers, and other agricultural machinery to enable precise navigation and automated operations. These receivers communicate with the machinery's control system, allowing for accurate guidance, steering, and application of inputs based on predefined maps or real-time data. It provides accurate location information, and GPS technology ensures that every pass the machinery makes is precise, minimizing overlaps and gaps.

GPS and Precision Farming
GPS technology in farming practices has opened up a wide range of applications in precision farming. These applications allow farmers to make data-driven decisions and optimize their operations for maximum productivity and sustainability.

1. Field Mapping and Soil Sampling

GPS technology enables farmers to accurately map their fields and create digital representations of their land. They can use that information with soil sampling data. So, farmers can gain valuable insights into the variability of soil properties across their fields. It allows practitioners to create more precise nutrients management plans, ensuring that fertilizers are applied at the right rates and in the right locations.

2. Variable-Rate Application

With GPS technology, farmers can create prescription maps that guide machinery to apply inputs, such as fertilizers and pesticides, at varying rates based on the specific needs of different areas within a field. It is a targeted approach that ensures the proper allocation of resources, reduces waste, and minimizes environmental impact.

3. Automated Steering

GPS-enabled automated steering systems guide machinery along predetermined paths with sub-inch accuracy. As we all know, automation reduces operator fatigue and minimizes human error, resulting in more precise operations and improved efficiency.

4. Yield Monitoring

GPS technology allows farmers to accurately measure and map crop yields across their fields. After collecting data from yields, farmers can identify areas with high or low yields, enabling them to investigate the causes and make informed decisions to optimize productivity.

5. Crop Health Monitoring

GPS-enabled sensors can be used to collect real-time data on crop health indicators, such as chlorophyll levels and canopy temperature. These indicators can detect early signs of stress or disease and help take proactive measures to prevent or mitigate crop losses.

How to get GPS trackers for Agricultural Use?

GPS technology can easily be implemented using small GPS tracking devices, specially designed to offer GPS based tracking and navigation. GPS trackers cost between INR 1000 to INR 5000 and can be easily connected with a smartphone to offer round the clock tracking and navigation facilities. These GPS tracker and Plug and use and can be attached to farming tools, machinery and assets to get real-time visibility over a long range, most suitable for outdoor settings.
