Circular chromatography is a technique used by biodynamic farmers to analyse the vitality and characteristics of soils, fruits and plants. These images are generated through a chemical process, and a time-bound ritual, by reaction of silver nitrate with light and the substance to be analysed. In this way, substances manifest their characteristics in images that are visible expressions of their qualities and vital forces, and can be read according to aesthetic parameters such as beauty, harmony of colour and vitality of form, as with works of art. It is a qualitative rather than quantitative analysis,
During the culture tour I collected samples of the soils of the different stops and for each one I created an image, an expression of the vitality of those soils.
