A dual-probe heat pulse (DPHP) sensor is a robust tool that can measure soil thermal properties and associated physical processes. new DPHP based was developed to simultaneously properties, water content matric potential. series of experiments were performed evaluate the performance. The able each property with acceptable accuracy. accuracy potential determinations approximately 10% in log scal...

When high tensions are developed in the water columns within the xylem of a shoot, the shoot wilts. If such wilting is induced by plugging a stem with gelatin immediately upon cutting, very rapid recovery results if the plugged portion is cut off under water in such a way as to prevent the entrance of air into the stem. Such recovery was observed by DIXON and BARLEE (1) as long as no gas entere...

Ehretia asperula’s physiological responses to growth performance following oak-wood biochar application under water stress conditions (WSC) and no (non-WSC) were investigated in a pot experiment. Biochar (WB) was incorporated into the soil at concentrations of 0, 5, 10, 15, 20 tons ha?1 before transplanting asperula pots. One month after transplanting, plants put by withholding for ten days. Wa...

ABSTRACT-This experiment was carried out to study particle size distribution (PSD) of carbonates in soils and its effect on some calcareous soil properties in Khuzestan Province, Iran. Soil samples (n=72) were collected from different regions. To evaluate the effect of carbonates on water contents at pressure head of -1500kpa and PSD of soil samples, these properties were determined before and ...

In order to understand the limits and dynamics of methane (CH(4)) oxidation in landfill cover soils, we investigated CH(4) oxidation in daily, intermediate, and final cover soils from two California landfills as a function of temperature, soil moisture and CO(2) concentration. The results indicate a significant difference between the observed soil CH(4) oxidation at field sampled conditions com...
