Accuracy of soil moisture measurement by tdr technique
time domain reflectometry soil moisture measurement error
2008/11/26
The error in the measurement of volumetric water content by the TDR technique results from the correlation imperfections between the directly measured values of soil refractive index, n, and the real ...
An automatic time domain reflectometry device to measure and store soil moisture contents for stand-alone held use
Time Domain Reflectometry TDR field device data logging soil moisture content
2008/11/26
A field setup was developed to measure soil moisture content on ten different positions using the Time Domain Reflectometry (TDR) technique. The setup has been designed to meet specific field demands...
Soil moisture and bulk electrical conductivity variability measured by TDR
TDR water content measurement soil heterogeneity random field parameters
2008/11/11
The result of numerous TDR measurements of heterogeneous soil water content are shown. Some statistical parameters of measured water content and bulk electrical conductivity fields are calculated. TDR...
Soil moisture storage and water-use efficiency of maize planted in succession to different fallow treatments
water use efficiency maize Pueraria phaseoloides Panicum maximum Euphorbia heterophylla
2008/11/11
Soil water storage and crop water use efficiency (WUE) were monitored in a randomised complete block design experiment set up on a 0.7 ha field plot with treatments that consisted of five fallow trea...
Spatial variability of soil moisture as information on variability of selected physical properties of soil
soil moisture soil bulk density infiltration rate TDR technique
2008/11/11
The paper presents a method for the estimation of variability of soil bulk density and of variability of infiltration rate on the basis of easily determinable variability of soil moisture. First, the ...
Spatial variability of soil moisture in grassland
soil moisture geostatistical methods fractal analysis
2008/11/11
The paper evaluates spatial moisture variation in research sites in Poland - Pszczew (Wielkopolska Province), Pawłowice (Dolny Śląsk Province), and in Slovakia - Tatranska Kotlina. The ...
