Natural field systems exhibit a large degree of soil heterogeneity which affects
the movement of water and solutes and thus leads to highly varying observations
of water contcnt and solute concentra...
Calibration of Time Domain Reflectometry for Water Content in Peat Soil
Time Domain Reflectometry Water Content Peat Soil
font style='font-size:12px;'>
2009/10/22
Since peat soil differs from mineral soil in several respects, mineral-soil calibration
functions for time domain reflectometry (TDR) are not necessarily applicable.
This paper evaluates a number of...
