Davis Soil Moisture and

Temperature Station

Protocol

Purpose

To log soil data using a Davis soil moisture and

temperature station

Overview

Soil moisture and temperature sensors are

installed at multiple depths and a station is

set up to measure and record measurements

at 15 minute intervals. These measurements

are transferred to your school’s computer and

then submitted to GLOBE via email data entry.

Gravimetric soil moisture measurements must

be taken to develop calibration curves for the

soil moisture sensors.

Student Outcomes

Students can view data for their soil that are

continuous and show variations within a day.

This enables detailed study of soil moisture and

temperature variations with time and depth.

Science Concepts and Scientiﬁc Inquiry

Abilities

Science Concepts and Scientiﬁc Inquiry Abilities are

gained through analyzing the data collected with

the weather station. Refer to the Gravimetric Soil

Moisture and Soil Temperature Protocols for the

Science Concepts and Scientiﬁc Inquiry Abilities

listed in their gray boxes.

Time

2 hours for site deﬁnition and set-up

Initial calibration requires doing the Gravimetric

Soil Moisture Protocol for at least the 30 cm

depth about 15 times over six or more weeks.

This will take 15 - 45 minutes each time.

15 minutes to use email data entry to prepare

and submit data to GLOBE periodically.

Level

Middle and Secondary

Frequency

Data reporting approximately once every week

Soil moisture sensor replacement and calibration

every two years

Materials and Tools

Soil moisture and temperature station and a

weather station with data logger

Computer capable of running weather

station software

Appropriate soil auger

Meter stick

Four soil moisture sensors

4-L soil holding/mixing buckets Water for

making mud balls (0.5 L)

One 120 cm x 2 cm PVC guide tube

Soil packing stick (e.g. an old broom

handle)

Pen or pencil

Calculator and graph paper or computer
