Study of Changes in Soil Moisture and Salinity Under PlasticMulch and Drip Irrigation in Pistachio Trees
In this study, changes in soil moisture and salinity contents in drip irrigation combined with white and black plastic mulches compared to no mulch (control) was evaluated. The experiment was carried out in two commercial pistachio orchards (Ohadi cultivar) with irrigation frequencies of 8 to 12 days with a total water consumption 4100 and 6170 m3ha−1. The study was conducted in a complete rand...
متن کاملPlant identity and shallow soil moisture are primary drivers of stomatal conductance in the savannas of Kruger National Park
Our goal was to describe stomatal conductance (gs) and the site-scale environmental parameters that best predict gs in Kruger National Park (KNP), South Africa. Dominant grass and woody species were measured over two growing seasons in each of four study sites that represented the natural factorial combination of mean annual precipitation [wet (750 mm) or dry (450 mm)] and soil type (clay or sa...
متن کاملSpatial soil moisture scaling structure during Soil Moisture Experiment 2005
Soil moisture state and variability control many hydrological and ecological processes as well as exchanges of energy and water between the land surface and the atmosphere. However, its state and variability are poorly understood at spatial scales larger than the fields (i.e. 1 km2) as well as the ability to extrapolate field scale to larger spatial scales. This study investigates soil moisture...
متن کاملStomatal response of an anisohydric grapevine cultivar to evaporative demand, available soil moisture and abscisic acid.
Stomatal responsiveness to evaporative demand (air vapour pressure deficit (VPD)) ranges widely between species and cultivars, and mechanisms for stomatal control in response to VPD remain obscure. The interaction of irrigation and soil moisture with VPD on stomatal conductance is particularly difficult to predict, but nevertheless is critical to instantaneous transpiration and vulnerability to...
متن کاملHourly and seasonal variation in photosynthesis and stomatal conductance of soybean grown at future CO
It is anticipated that enrichment of the atmosphere with CO 2 will increase photosynthetic carbon assimilation in C3 plants. Analysis of controlled environment studies conducted to date indicates that plant growth at concentrations of carbon dioxide ([CO 2 ]) anticipated for 2050 ( ~ 550 m mol mol 1 ) will stimulate leaf photosynthetic carbon assimilation ( A ) by 20 to 40%. Simultaneously, con...
