The goal of this study was calibration of the ECH20 soil moisture sensor EC-5 and the sensor SM200 for selected soils of the Czech Republic. Based on the soil maps of the Czech Republic and various cl...
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...
TDR (Time-domain reflectometry) is an advanced method for monitoring the water content in fields.TDR measurements can provide accurate information about vegetation effects on both spatial and temporal...
There was a heavy rain fall on Nov. 19-20 and Dec. 26-27, 2006 in Ibaraki-prefecture. We examined wheat growth and soil conditions in a large paddy field in Inashiki-city, Ibaraki-prefecture, where p...
We adopted the 'inter-row strip tillage' (IST), in which furrows between rows are tilled and seed is sown on the ridge which is covered with the tilled furrow soil, to the soybean cultivation in upl...
This research was carried out from 1993 through 1995 for a two-year period in dry farming areas of Haymana/Ankara. The aim of the research was to determine the available water content of the 0-60 and ...
The canopy temperature of rice at the flowering stage and the soil water content were investigated under different soil water treatments (the soil water contents were 24%, 55%, 90% and 175% at the flo...
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 ...
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 ...
