This capability is especially valuable in regions where water resources are limited, supporting sustainable agricultural practices.
Implementing Variable Rate Irrigation
Drones also facilitate variable rate irrigation (VRI), where water is distributed unevenly across a field based on the specific requirements of different areas. By identifying which areas need more or less irrigation, farmers can optimize water use, delivering precisely what each section of the field requires.
As the name implies, variable rate irrigation (VRI) adjusts the irrigation levels to deliver water precisely to your crops throughout their growth cycle. Drones can precisely detect and ensure whether the right amount of water or chemicals is applied to the right areas at the right time.
This not only conserves water but also promotes healthier crops and reduces operational costs.
Advancing Harvest Planning
Harvesting is one of the most critical phases in agriculture. Drones play an essential role in optimizing this process.
Yield Prediction
Using data collected throughout the growing season, drones can help farmers estimate crop yields more accurately. This predictive capability allows for better planning and resource allocation during the harvest.
Farmers can make informed decisions regarding labor, equipment needs, and logistics, thereby reducing waste and maximizing profits.
Studies have shown that drone analyses combined with machine learning produce highly accurate results in estimating crop yields. This allows farmers to determine how much produce they can expect before the harvest even begins. (Source: International Journal of Statistics and Applied Mathematics 2023; SP-8(5): 961-969)
Enhanced Harvesting Techniques
Drones can also assist in the physical harvesting process by mapping out fields and guiding machinery.
By providing a precise overview of the field, they can help operators identify which areas are ready for harvest, ensuring that the process is efficient and timely.
