Robust and cost-effective system for measuring and logging of data on soil water content and soil temperature profile
Data-Logger Soil Temperature Soil Water Content Microcontrollers Sensors
2013/3/4
The paper describes the system for measuring and logging of data on soil water content and soil temperature profile. The system was tested in a field and shows great potential for performing continuou...
Effect of aggregate size on the water content estimated with time domain reflectance (TDR)
TDR calibration aggregated soil
2008/11/24
Time domain reflectance (TDR) gives reliable estimates of the water content of structure-less soil. The effect of soil structure on the performance of TDR has received relatively little attention in c...
Comparison of soil thermal properties in cultivated fields determined using soil water content measured by two methods
soil thermal properties soil water content TDR methods
2008/11/21
Results of the measurements of water content in the topsoil layer (1-6 cm) in fields with various crops obtained by gravimetric and reflectometric (TDR) methods have been used for the calculations of ...

Water is very important component forming practically all important properties of the agricultural products, the foods and the biological objects. Among the properties, the important role is played b...
Relationship between the impedance of a multi-pin probe and soil water content
impedance dielectric constant soil water content multi-pin probe model
2008/11/12
Based on the theory of the impedance-transform of transmission line, a mathematical model for calculating the impedance of a soil probe with a multi-pin structure was developed. It is found that the ...
Soil tensile strength as affected by time, water content and bulk density
soil tensile strength Brazilian test age-hardening
2008/11/11
We investigated the effect of soil water conditions and soil compaction on the age-hardening process of loamy sand and silty loamy sand in relation to the tensile strength. Soil samples from Germany (...
