Precision Agriculture
Precision agriculture, or site-specific farming, is a system to better manage farm resources. It requires the use of new technologies, such as global positioning (GPS), remote sensing (RS), satellites or aerial image, geographic information systems (GIS), yield monitoring devices, and variable rate technologies (VRT) to assess and understand variations. Collected information allows farmers to identify, analyze, and manage the spatial and temporal variability of soil and plants for optimum profitability, sustainability, and protection of the environment.
GIS are a powerful information technology for analysis and management of spatial data and mapping. RS to identify and GPS to locate and define spatial features or activities contribute to the quality of site-specific practices. VRT allows targeted, site-specific input applications. Yield monitoring records crop productivity as an historical database for crop management.
