University of Pretoria (UP) researchers, in collaboration with the Council for Scientific and Industrial Research (CSIR), have developed innovative maps to assist maize farmers in Gauteng with precision weeding. These maps, created from Copernicus Sentinel-2 satellite images, distinguish between maize plants and weeds, allowing farmers to target weed removal more effectively and reduce the use of harmful chemicals. Master’s student Yoliswa Mkhize led the project under the guidance of Professors Abel Ramoelo and Moses Azong Cho, highlighting the potential for similar applications in other crops across South Africa. The initiative aims to enhance agricultural efficiency while minimizing environmental impact and was published in the journal Physics and Chemistry of the Earth; also have a look at the infographic that explains the research. Information on the CSIR's capabilities related to precision agriculture can be accessed here and here, or view the video on their work below.

Additionally, a film documenting this research will be produced by Voice of America, with filming scheduled for October 30, 2024, at the Department of Geography, Geoinformatics and Meteorology computer lab and the University of Pretoria's farm. This collaboration underscores UP's commitment to sharing innovations in precision agriculture with broader audiences.
