Soil water content has an important impact on many fundamental biophysical processes. It affects the germination of seeds, plant growth and nutrition, microbial decomposition of the soil organic matter, nutrient transformations in the root zone, as

. Plant water stress can be measured either by the negative water potential in plant tissues or by the incremental heating of the crop canopy resulting from water stress. Other irrigation scheduling options rely on the measurement of soil water content or

quality was also tracked to establish an understanding of the relationship between soil water status and canopy aesthetics. Plant-available water, a subset of total soil water, has been correlated with a number of plant responses from leaf expansion to

). Root growth adjustments are crucial for efficient utilization of the available soil water and to get better yield under DI conditions ( Xue et al., 2003 ). Root traits such as root thickness, rooting depth, and root penetrating capacity through highly

Northern highbush blueberry is a shallow-rooted plant that can easily deplete available soil water within a few days without rain or irrigation ( Bryla and Strik, 2007 ; Bryla et al., 2011 ; Ehret et al., 2012 , 2015 ). Consequently, most

harvest yields increased to 15.25 Mg·ha −1 ·(3 yr) −1 . Several irrigation monitoring methods are available to growers when managing crop production including pan evaporation (PE), reference evapotranspiration (ET o ), or soil water measurements. Soil

Soil water repellency (SWR) is a condition in which a soil does not spontaneously wet when a drop of water is applied to the surface, indicating that the soil is hydrophobic ( Müller and Deurer, 2011 ). In recent years there has been greater

compacted soil, weed cloth, or gravel. Given these considerations, soil water samples extracted with suction lysimeters from below the root zone may serve as indicators of solute concentrations in leachate, but should be interpreted cautiously, especially

Irrigation application in orchards should be timed so that tree water status is maintained at a level sufficient for optimum production. Irrigation scheduling decisions based on plant responses rather than measurements of soil water status have
