Technical Abstract: The article describes the concepts of precision agriculture technology including the acquisition process of geo-referenced data, the data manipulation and decision making process, and the site specific application of agricultural inputs. Examples using yield maps obtained for corn and soybean crops in 1993 and 1994 are shown as well as grid soil sampling maps sobtained for phosphorus and organic matter for the same field, located nea Centralia, MO. The current application of this technology in the state of Missouri, with emphasis on the research projects developed by the USDA-ARS Cropping Systems and Water Quality Research Unit, are briefly described. The current use and development of electronic sensors for application in precision agriculture are briefly discussed. The article concludes with a short session on the future of technology and the challenges that it faces for being fully accepted by farmers in the USA and around the world.
