In our laboratory, soil texture (fine sand, silt and clay) can be analysed using sedimentometry with the Sedigraph instrument. Spectrophotometers are used for plant pigment or soil microbial enzyme composition or plant nutrient concentrations. Finally, X-Ray fluorescence is used as a screening technique to determine the ca. 50 most abundant elements starting in the periodic table of elements with light elements like Na until heavy elements like U.
