Demonstration experiment using wireless data communication to send readings to a large-size display. Knowledge of soil characteristics is highly important for agriculture. To familiarise students with this topic, two sub-experiments use pH readings to demonstrate how different soils from different places can be (sub-experiment "Characteristic pH values for soils") and how varied the soil can be down below the surface (sub-experiment "Soil profiles").
