Benefit To Soybean Farmers
Soybeans are grown on significant acreage in every county in Maryland; however, production in several Maryland counties (and throughout the northeast) is on smaller, fragmented fields. These small, often irregularly-shaped fields, can make it a challenge for farmers to apply necessary crop protection products (such as herbicides and fungicides) with modern ground spray equipment; and aerial applications with helicopters or airplanes may not be suitable for every field as a result of size, shape, topography, and/or proximity to field edge vegetation or buildings.
With the rapid advancement of drone technology, the possibility of aerial pesticide applications with drones is now realistic, and as a result, drone applicator companies are popping up and offering this commercial pesticide application service to farmers. However, there are several unanswered questions with this new method of application and there is very little research regarding spray coverage and efficacy from drone applications. Likewise, even less is known about the efficacy of aerial seeding cover crops into standing soybeans using drones. A literature review of the subject returns only a handful of references, indicating that very little research has been conducted. The studies that have investigated using drones as sprayers focus on the engineering and physical constraints of drones (lift capacity, battery life, GPS, user interface, etc.) and not as much on the agronomic issues, such as spray coverage or their practical application in row crop agriculture1-5.
This project aims at collecting data to start to answer some of these questions. We propose partnering with a commercial drone applicator and local farmers to; 1) evaluate spray coverage achieved with drone application in soybean; 2) evaluate cover crop establishment flown on standing soybeans using a drone applicator on cooperating local farms. Results from this project will be published in several forms to disseminate the information to both growers and peers in academia (objective 3). This proposal is for the second year of this study (2021), building on preliminary data that we collected in 2020.
