In the theoretical part of this thesis there is summarized basic knowledge about precision agriculture, soil condition monitoring, mapping yield and state of vegetation. The practical part deals with evaluation of yield heterogeneity, creating yield maps, and verification of Isaria online sensor system for variable application of nitrogen fertilizers. The methodology of the work was based on the collection of data from the Isaria sensor system and the yield data from combine harvesters on the land of Zdounky center of SALIX MORAVA a.s. during 2016. The available documents were processed using tools in geographic information systems and then statistically compared to each other, including the underlying maps of the yield potential and satellite data of remote sensing. The significance of dependencies of the above mentioned factors was evaluated by correlation analysis and linear regression. The results show that the varying degrees of dependence were found between variables. |
