Measurement of the matric potential of soil water in the rhizosphere [PDF]
The availability of soil water, and the ability of plants to extract it, are important variables in plant research. The matric potential has been a useful way to describe water status in a soil-plant system. In soil it is the potential that is derived from the surface tension of water menisci between soil particles.

Calibration of Watermark soil moisture sensors for soil matric potential and temperature
Plant and Soil, 1992Rapid, accurate, and automated measurement of soil matric potential is desirable. Evidence suggested that the Watermark resistance block might be an appropriate and inexpensive tool, so we conducted an evaluation of its relevant characteristics. A number of these blocks were calibrated under laboratory conditions to determine their individual and ...

Quantifying Coupling Effects Between Soil Matric Potential and Osmotic Potential
Water Resources Research, 2023AbstractSoil matric potential and osmotic potential are widely accepted as two independent components of total soil water potential. However, laboratory observations repeatedly demonstrated that matric potential can vary with salt concentration, implying a potential coupling between matric potential and osmotic potential.

The Influence of a Water Absorbing Geocomposite on Soil Water Retention and Soil Matric Potential [PDF]
Climate change induces droughts that are becoming more intensive and more frequent than ever before. Most of the available forecast tools predict a further significant increase in the risk of drought, which indicates the need to prepare solutions to mitigate its effects. Growing water scarcity is now one of the world’s leading challenges.

Changes in the Matric Potential of Soil Water With Time and Temperature
Soil Science, 2010The temperature dependence of the matric potential of soil water was investigated as part of a study of the effects of climate change on soil physical properties. Undisturbed samples of topsoils were collected in cylinders. The pore water suction near the center of each cylinder was measured using two miniature tensiometers.

Effect of Soil Matric Potential on Urea Hydrolysis
Soil Science Society of America Journal, 2014Soil water availability affects NH 3 loss from surface applied urea, partly due to its influence on urea hydrolysis rates. However, the quantitative effects of soil water on hydrolysis rates are not well understood.

Influence of Soil Bulk Density on Matric Potential
Soil Science Society of America Journal, 1962Abstract Unsaturated soil samples were compressed at three different moisture contents and temperatures to evaluate these interrelations with soil moisture matric potential. It was found that in all cases increasing bulk density, at constant moisture content and temperature, resulted in an increase in soil moisture matric potential ...

An implicit model for soil thermal conductivity and matric potential
2021<p>Soil thermal conductivity (&#955;) is affected by the energy status of water and is closely related to soil matric potential (h). In this study, a soil water retention curve and a soil thermal conductivity curve were linked via the critical point that separated the adsorption water and capillary water regimes. Based on existing
