When people hear “precision agriculture,” they think of farming with a more precise approach. In a way, they are right; it involves the use of technology and tools to improve soil health, land fertility and productivity. Precision agriculture technologies, such as agricultural yield analysis and controlled fertilizer dosing, have been a part of the sector since the 1990s.
Sadly, according to a 2023 report from the U.S. Department of Agriculture (USDA), only 27% of U.S. farms or ranches incorporate precision agriculture practices in farming and animal management. However, with the U.S. government supporting precision agriculture technologies by sponsoring research, education and loan programs to create more tools for farmers, the adoption of precision agriculture is expected to increase. This article aims to raise awareness about precision agriculture by outlining its benefits and applications.
Joe’s parents are renowned farmers in their community. They follow traditional methods such as manual planting, fertilization application, and harvesting. The family has always boasted of bountiful harvests every season.
Unfortunately, productivity began to decline, and things took a turn for the worse. Fortunately, Joe, a graduate in agricultural science, returned to serve his community. While in school, he learned about precision agriculture and believed it was exactly what was needed to turn the family’s situation around.
Like Joe’s parents, many farmers face similar challenges, and the simple solution is to practice precision agriculture. Precision agriculture uses technology to ensure that crops and animals receive the right resources at optimal levels, thereby minimizing waste, production costs, environmental pollution and improving overall efficiency.
How Does It Work?
Precision agriculture utilizes information technology and software such as automated irrigation systems, drones, GPS, satellites, sensors and analytic software to gather data on soil health, animal health, crops, air, weather predictions, equipment and labor costs. Other functions include:
- Farmers can use real-time data obtained from sensors to measure soil moisture content, humidity, and temperature. They can also use drones and satellites to get detailed images of crops and plants.
- This information helps farmers make accurate decisions, such as determining the best time to plant based on weather conditions.
- It ensures that only the necessary resources are applied, minimizing waste.
Livestock and cattle farmers are also benefiting from precision technology. Using data collected from various sources, they can monitor the health of their animals in real-time.
Benefits of Precision Agriculture
After data collection, the next step is analysis, which helps farmers understand the health status of their animals, manage crop rotation, optimize soil treatment, and plan the best times for planting and harvesting. The Integration of sensors and other imaging technologies helps farmers identify which crops, plants, or soils need treatment. It also helps detect areas in need of intervention due to poor soil conditions, drought, or other issues.
These insights allow farmers to apply the right amount of fertilizer, manure, pesticides or water. Precision agriculture ensures minimal runoff of fertilizers or pesticides into groundwater or water bodies, promoting resource conservation and reducing environmental impact.
Application Of Precision Agriculture
In the past, precision agriculture was largely limited to large farms, which had the financial resources and infrastructure to adopt such technologies. Today, however, with advances in mobile apps, drones, cloud computing software, and sensors, even medium and small-scale farms, including family farms, can benefit from precision agriculture.
Here are some popular applications of precision agriculture:
- Soil and Crop Monitoring Sensors
Soil sensors measure nutrient levels, microbial activity, water content, and temperature in real-time. This provides farmers with valuable insights into soil health, especially in areas where the soil is suspected to be poor, enabling them to treat it as needed.
- Automated Irrigation Systems
Irrigation is triggered based on the data obtained from soil sensors and weather forecasts, optimizing the watering schedule. This reduces water wastage and promotes healthier crops.
- GPS-Guided Equipment
GPS technology helps tractors and other equipment operate with precision, minimizing overlaps during planting or harvesting and reducing operator fatigue, particularly on large farms.
- Robotics for Weeding and Harvesting
With precision agriculture, farmers can bid goodbye to manual weeding and harvesting. Robots equipped with artificial intelligence are now capable of weeding, planting, and harvesting crops. This reduces labor costs and increases efficiency while ensuring greater precision in these tasks.
- Remote Sensing and Aerial Imaging
Aerial sensors, drones and satellites monitor crop health, moisture levels, temperature, and pest infestation. This data helps farmers to make prompt, data-driven decisions. In pest management, sensors help determine the optimal amount of pesticides needed, preventing excess runoff into water bodies.
- Yield Monitoring Systems
An increase in productivity is the joy of every farmer. This system tracks and measures the number of crops harvested per area, helping farmers identify areas with high, low, or average productivity. Based on the data, it provides recommendations for improving efficiency.
- Data Analytics and Farm Management Software
Farm management software compiles data from various sources and helps farmers make strategic decisions that can increase profits. Many of these platforms include tools for crop modeling, predictive analysis and weather forecasting.
