Investigations of precision agriculture technologies with application to developing countries

Precision agriculture (PA), also known as "site-specific management (SSM)", "prescription farming", or "variable-rate technology", offers a practical option to address the rising food demand for optimal and sustainable agriculture. Effectively identifying and analysing the spatial and temporal changes in the fields requires the application of agriculture sciences and information technologies. To sustainably conserve natural resources, including water, air, and soil quality, while reducing production costs, various precision agriculture approaches have evolved worldwide. The application of sensor-based technology and remote sensing modifies conventional farming methods. The agricultural industry has grown remarkably due to this modernization of agriculture. This study analyses every technical facet of precision agriculture. It looks at different sensor types and pertinent technology related to precision farming. Precision agriculture and the tools and technologies needed to implement it are also discussed, with an eye on the needs of small-scale farmers in developing countries.
