LifePlan plot soil moisture data

Dataset ID
LifePlan 07
Abstract
Slope orientation and slope angle result in differences in the quantity of solar radiation received by the land surface at clear skies. The differences in the energy received, in turn, impact evapotranspiration and soil plant available water. To scope the degree of differences in surface root zone moisture availability, three soil moisture and temperature sensors (TMS-4) were placed from highest to lowest elevation along a steep slope within the Lifeplan plot (mixed broadleaf - conifer montane rain forest). In addition, at the base of the slope, three Decagon EC 10 HS sensors, connected to a Decagon Em5b logger were installed in at 25, 50 and 100 cm depths to supply soil moisture data against modelled water availability values.
Purpose
Detect differences in surface soil moisture along a hillside to define an adequate sampling design for soil microbial diversity and soil carbon sampling.

Methods
TMS-4 sensors inserted perpendicular to the soil surface along a slope of ca. 45 deg. for continuous logging of soil moisture at 10 cm depth; temperature at -6 cm, 2 cm and 15 cm above the soil surface are also recorded at 15-min interval.
One set of three Decagon EC 10 HS sensors, connected to a Decagon Em5b logger, installed at 25, 50 and 100 cm depths at the foot of the slope. Removed after equipment failure.
Quality Assurance
Sensors were calibrated in the factory and have been recording since ...
