Deactivated: Soil Moisture Sensor Protocol

The Soil Moisture Sensor Protocol measured the water content of the soil based on the electrical resistance of soil moisture sensors. Using meter readings from soil moisture sensor blocks, students developed a calibration curve to determine soil water content at depths of 10 cm, 30 cm, 60 cm and 90 cm.
