Some Possibilities of Studying the Precision Farming in Estonia, Methods and Results Ofcomplex Investigation

It is a fact that crops growth conditions vary greatly in the same field. Provisionally actual growth conditions are made up of many components, i.e. variation of natural conditions (climate & soil), results of effect of machinery on soil ( soil compaction) and unfavourable conditions for plant growing. In Estonia rather widely used ATV are causing remarkable damage to landscapes. All collected data were georeferenced by means of a GPS-receiver and postprocessed for position correction. For ATV damages assessment the trajectory was recorded. On damaged sites both area and form of damage were assessed. The collected data were compared to the digital soil map. Economic loss on the average, due to unfavourable conditions for plants growth in the case of winter rye "Portal" was 131 euros per ha, for Melilotus 18.5 euros per ha and for spring barley "Anni" 1000 euros per ha.
