In other words, the use of various data gathering techniques to increasing yield while decreasing costs. If time permits I will mention some of the other applications of technology. The first step in crop production optimization is usually yield mapping but this emerging technique could be described as a three step process. Data collection, Data analysis and Implementation. Data Collection Data collection actually involves the collection of a variety of types of information, usually geo-referenced, for the purposes of analysis.
Yield mapping is the process of acquiring accurate geo-referenced yield information.
Ideally, several years' data is helpful in obtaining the clearest picture of the factors influencing yield. The hardware involved in yield mapping is a significant point of contact between the producer and the technology. He must often deal with the difficulties of installation, configuration, calibration and operation if he is to obtain useful data. This can be both rewarding and frustrating. Yield mapping systems centre around a field computer which accepts data from the yield, moisture and other sensors, a global positioning receiver and a user interface.
