Abstract: A root uptake model developed and validated for a uniform crop root zone in a semiarid agroclimate is tested for its efficacy in predicting moisture depletion in a multilayer crop root zone in a subtemperate, subhumid ...

Abstract: The core of salinity problems starts from the fact that irrigation waters contain some amount of dissolved salts. Soil moisture salinity is dependent on soil type, climate, water use, and irrigation. The root water-uptake ...

Abstract: This paper presents a new control surface, which we have named auxiron, that helps a solar-powered aircraft to orient itself according to the position of the sun in the sky to collect more solar power. The auxiron also ...

Abstract: Soil-water movement due to root-water uptake, is a key process for plant growth and transport of water in the soil plant system. There are different root-water uptake models to determine the extraction rate of soil moisture ...

Abstract: An empirical relationship is developed for the nonlinear root water uptake parameter in the O-R moisture uptake model from easily measurable plant physiological parameters, such as maximum daily transpiration, maximum root ...

Abstract: Root water uptake is often modeled as a sink term in the Richards equation to account for evapotranspiration losses. The sink term is assumed to be a power law function in the nonlinear root uptake model (O-R model) to ...

Abstract: The crop water stress index (CWSI) is a reliable indicator of water status in plants and has been utilized for stress monitoring, yield prediction, and irrigation scheduling. Despite this, however, its use is limited because ...
