Summary

Rocket lettuce from a field trial with biodynamic, organic and mineral fertilization with or without horn silica application was investigated with the image forming methods copper chloride crystallization, capillary dynamolysis and round filter chromatography with two approaches. Firstly, image evaluation by two individual evaluators was based mainly on analysing structural features in capillary dynamolysis, secondly, a panel of eight evaluators analysed both structural and Gestalt criteria of copper chloride crystals. With the first approach, the two manure fertilizers were differentiated from the minerally fertilized sample, while with the second approach, biodynamic fertilization was differentiated from organic and mineral fertilization, and samples with horn silica application were successfully identified. Apparently, biodynamic preparations affected Gestalt criteria more than structural aspects. Gestalt recognition may be a method to capture properties of the farm organism that emerge from the integration of different components.
