Precision agriculture (also called precision farming) is disrupting the traditional farming industry. In fact, according to precision agriculture studies, precision farming technologies have already increased farmers’ production by 4%, reduced fertilizer use by 7%, decreased herbicide applications by 9%, lowered fossil fuel use by 6%, and gained 4% savings in water.
Whether you’re a small-scale farmer looking to optimize your resources or an agricultural professional seeking to enhance productivity and sustainability on a larger scale, precision agriculture can be a great option. Understanding its uses, from farm mapping to crop condition monitoring and beyond, and its benefits is just the beginning of a journey toward harnessing its full power for your farm.
What is precision agriculture or precision farming?
Precision agriculture, also known as site-specific crop management or precision farming, transforms traditional farming into a high-tech operation driven by data and computational power. It involves using navigational technology to gather detailed information about soil conditions, crop status, and weather predictions to make informed farm management decisions.
Precision farming relies on two fundamental technologies: Global Positioning Systems (GPS) and Geographic Information Systems (GIS). These technologies work hand-in-hand to collect and analyze site-specific data. While GPS provides the positioning and tracking information necessary to accurately monitor farm machinery and crop status, GIS enables spatial and geographical data analysis and visualization. Together, they help facilitate decision support for within-field management.
However, to tap into the full potential of precision agriculture, farmers need more than just GPS; they need the precision of Real-Time Kinematic (RTK) corrections. RTK enhances GPS data by correcting signal distortions and providing centimeter-level accuracy. This level of detail is crucial for tasks requiring high precision, such as seed placement, fertilizer application, and creating detailed farm maps.
Without RTK, managing farms to meet modern needs can be laborious, costly, and imprecise. Most farmers need an accuracy of less than 10 centimeters to achieve accurate mapping. This often leads them to two options: installing a ground-based base station, which involves significant setup and an upfront cost of $4,000, or legacy RTK networks with prohibitive costs of almost $500 per month per drone.
With RTK from Point One Polaris, farmers get affordable and highly accurate RTK–even in remote areas. For many farmers, introducing drones equipped with RTK technology streamlines processes that once took days into a single flight, reducing inspection time to 30 minutes. This not only saves time and money but it also means more precise data collection.
Why do farmers need precision agriculture?
Traditionally, managing a farm involves a lot of guesswork and manual labor. In the past, workers had to trek miles on foot across their fields to collect data about their farms, a costly and inefficient method.
This outdated approach to monitoring and managing fields is not just expensive; it’s also imprecise. In contrast, precision agriculture offers a smarter, more efficient way to understand and respond to the needs of each plot of land.
With precision agriculture, farmers have the power to oversee and manage their fields remotely. Even small-scale farm owners can efficiently manage large tracts of land or multiple small plots without stepping foot on them. This technological leap forward not only enhances the efficiency of crop management but also brings about significant cost savings–all while boosting production.
Precision agriculture is also crucial in optimizing soil use and preserving its quality for future generations. This ensures a stable and sustainable food supply, which is crucial in addressing the global hunger challenge. By making each plot of land as productive as possible without degrading its health, precision agriculture is a beacon of hope for feeding the world’s growing population.
Take, for example, the process of vineyard inspection. Farmers can inspect crops for disease prevention and plant health using drone-based photogrammetry. By photographing entire fields with the RTK network from Point One, experts in winery technology and vineyard management can stitch those photos together for highly detailed maps. With the help of AI-based image recognition software, winemakers can identify common diseases like powdery mildew and pinpoint the specific vines affected for precise treatment.
