| 摘要 |
<p>The present invention relates to methods for establishing for yield maps for use in agricultural management. The method involves harvesting a field using a harvesting machine (1) equipped with a plurality of sensors (47, 70, 89, 92, 106, 120, 130) monitoring crop and/or harvester related parameters, such as the mass flow rate of the crop. The data are logged by an onboard computer (101) and combined with data from a speed sensor (100) and a positioning sensor (99) for establishing maps showing the spatial variation of the monitored parameters.</p><p>Other data provided by one or more of the sensors are used for validating or ignoring the data for use in the map. In the case of a combine harvesting grain, this may involve data from a sensor (89) indicating the presence of lodged crop in front of the header (14).</p> |
