Soil moisture sensors (sometimes referred to as volumetric water content sensors) measure the water content of soil. These sensors can be used to estimate the amount of stored water in a profile or how much irrigation is required to reach a desired amount of water in the soil. These sensors...
Volumetric water contentAlthough soil moisture sensor-based automated irrigation systems enable researchers to grow plants efficiently and quantify drought stress via constant control of volumetric water content (VWC), growers, in practice, typically irrigate plants using excessive amounts of water based ...

Response of soil moisture to fertilization in maize fields Compared with the treatment without fertilization, the effects of fertilization on the water content in the 0–200 cm soil layer (Fig.3a) were not homogeneous. Organic fertilizer (O) alone significantly increased the soil water content (3....
The moisture content of soil greatly affects its thermal conductivity (Demir et al., 2009). The voids in the soil get filled with water, which subsequently increases the bridging between the soil particles thus, improving the thermal conductivity. Sodha et al. (1990) investigated the EAHE pipe...
volumetric water content at our site due to the heating treatment5. In seasonally dry ecosystems such as this Mediterranean site, soil moisture can affect microbial community structure and function throughout the soil profile53; however, we did not find significant correlations between soil moisture ...
water status of 30 wine grape cultivars grown side by side during soil dry down from above field capacity to close to the permanent wilting point. We aimed to test two hypotheses: (i) grapevine Ψpdequilibrates with Ψsoilacross the soil moisture spectrum (i.e., Ψpd = Ψsoil); ...
Three soil properties were also measured at each microsite: (1) volumetric water content within the top 3.8 cm of the soil (TDR 300 soil moisture meter; Spectrum technologies; USA), (2) soil resistance to penetration at 5 mm depth (as a measure of soil compaction) using a hand-held...
The fitting soil moisture for maintaining a high level of Pn and WUE was in range of 15.3%–26.5% of volumetric water content (VWC), of which the optimal VWC was 23.3%. Under the condition of fitting soil moisture, the light saturation point of leaves occurred at above 800μmol·m2·s1...
