Precision agriculture is a farming management concept that utilizes technology to gather, analyze and manage data in order to improve crop yield and efficiency. It relies on the use of information technology such as satellite imagery, sensors, and geographic information systems (GIS) to monitor and adjust inputs to crops on a field-by-field basis. This data is used to optimize inputs such as fertilizer, water, and pesticides, and to improve crop yield, reduce costs, and reduce environmental impact.
