Principle

Information concerning the quality of soils is of great importance for agricultural production. The students are familiarised with this subject via two experiments with pH measurements that show how much soils may differ from each other (experiment  "Characteristic pH values of various soils") and how significant the differences within a soil itself may be (experiment "Soil profile").
