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").
