Popis:	Spatially variable field operations depend on various parameters such as in-field variations of soil and crop yield. A yield map can provide local information on nutrient absorption, variability of soil and effects of special treatment strategies. In order to monitor the spatial variations of yield the combine harvester has to be equipped at least with data acquisition for locating and measuring grain flow and area productivity. Accuracy of yield mapping can be increased by additional measuring of grain moisture, actual cutting width and the dynamics of the grain transport within the combine. This paper comments on special technical problems encountered during yield mapping on a combine and presents the technical equipment. The suitability of the sensors has been examined in laboratory and field tests.
