A novel heat-pulse probe for measuring soil thermal conductivity: Field test under different tillage practices

Open hardware portable dual-probe heat-pulse sensor for measuring soil thermal properties and water content

Laboratory Evaluation of the Dual-Probe Heat-Pulse Method for Measuring Soil Water Content

to evaluate the level of accuracy and precision that can be achieved with the DPHP method. Tarara and Ham The dual-probe heat-pulse (DPHP) method provides a means of (1997) conducted a laboratory experiment in which estimating volumetric soil water content ( ) and change in volumetric water content ( ) from measurements of volumetric heat capacity. DPHP-based estimates were compared with values...

Pulse accumulation, radial heat conduction, and anisotropic thermal conductivity in pump-probe transient thermoreflectance.

The relationship between pulse accumulation and radial heat conduction in pump-probe transient thermoreflectance (TTR) is explored. The results illustrate how pulse accumulation allows TTR to probe two thermal length scales simultaneously. In addition, the conditions under which radial transport effects are important are described. An analytical solution for anisotropic heat flow in layered str...

Tillage and soil quality Tillage practices for sustainable agriculture and environmental quality in different agroecosystems

For centuries tillage has been used to prepare suitable seedbed to grow crops, and to control weeds and incorporate fertilizers, pesticides, manures and other amendments. In early years conversion of native ecosystems by tillage helped to unlock nutrients stored in soil organic matter, and thus `mine' naturally fertile soils to grow crops with minimum inputs for the growing population. However,...

Impacts of different tillage practices on some soil microbiological properties and crop yield under semi-arid Mediterranean conditions

Effects of six tillage practices on some soil microbiological properties and crop yields were evaluated for a clay soil (Typic Haploxererts) under semi-arid Mediterranean conditions in a three year study (2006-2009). The experiment was designed as a completely randomized-block with three replications. Treatments were: conventional tillage with residue incorporated (CT1), conventional tillage wi...
