WebMay 28, 2013 · This gradient is propagated through the plant along a continuous water column that is under tension, ultimately resulting in the uptake of water occurring at high … The soil-plant-atmosphere continuum (SPAC) is the pathway for water moving from soil through plants to the atmosphere. Continuum in the description highlights the continuous nature of water connection through the pathway. The low water potential of the atmosphere, and relatively higher (i.e. less negative) water … See more The transport of water along this pathway occurs in components, variously defined among scientific disciplines: • Soil physics characterizes water in soil in terms of tension, • Physiology of plants and animals … See more • Ecohydrology • Evapotranspiration • Hydraulic redistribution; a parameter now being considered in the soil-plant-atmosphere … See more
As Earth warms, more ‘flash droughts’ suck soil, plants dry
WebFeb 5, 2024 · AbstractAccurate estimation of the soil water balance of the soil-plant-atmosphere system is key to determining the availability of water resources and their optimal management. Evapotranspiration and leaching are the main sinks of water from the system affecting soil water status and hence crop yield. The accuracy of soil water … WebApr 14, 2024 · Water ages in plant transpiration reveal important processes of water dynamics in soil-plant-atmosphere continuum, which is regulated by water variability and availability in both precipitation inputs and root zone. However, the impacts of climate patterns and rooting depth on water age dynamics in transpiration are inadequately … d and a cycle decatur in
