Field water balance measurements using monolithic lysimeters were used in validating the Cupid-DPE model for predicting water loss partitioning during sprinkler irrigation from a moving lateral system fitted with impact sprinklers and spray nozzles. The model combines equations governing water droplet evaporation and droplet ballistics with a comprehensive plant-environment energy balance model...

This study was conducted July of 2012 in Iowa, in WARM (<26.7 °C) and HOT (≥26.7 °C) weather. Four sprinkling methods were compared, with one treatment being randomly assigned to each load: control- no sprinkling (not applied in HOT weather), pigs only, bedding only, or pigs and bedding. Experiment 1 used 51 loads in WARM- and 86 loads in HOT weather to determine sprinkling effects on pig measu...

The domestic and foreign research in the field of rice cultivation carried out over past 10-15 years has identified four main promising technologies that can reduce cost produced: 1 - intermittent flooding; 2 periodic moistening without creating a layer water; 3 sprinkling, including surface irrigation; 4 drip irrigation. Drip irrigation is most priority area research, since it significantly ra...

This paper presents research which has defined a new typology of urban patterns (sprinkling), different from the internationally recognized standard urban sprawl, as well as various indicators that have been implemented to measure sprinkling. It is important to highlight that the damage caused to the environment and communities by urban sprinkling is much more serious and irreversible than that...

The spay under pressure is an effective save of water, this task should be automated and controlled in order to limit the waste of water and the facilities of damages. For this reason, it's necessary to find a mathematic model describing the irrigation process. In order to facilitate this step the fuzzy model of takagisegeno is the best approaches to the representation of nonlinear systems. Var...

the spray under pressure is an effective save on water. This task should be automated and controlled in order to limit the water waste and the facilities of damages. For this reason, it's necessary to find a mathematical model describing the irrigation process. In order to facilitate this step the TakagiSugeno fuzzy model is the best approaches of nonlinear systems representation. Various techn...

r a 200 .011 .: +86 27 .edu.cn Summary Tritium and bromide were used as applied tracers to determine groundwater recharge in Hebei Plain, North China, to evaluate the impacts of different soil types, land use, irrigation, and crop cultivation practice on recharge. Additional objectives were to evaluate temporal variability of recharge and the effect on results of the particular tracer used. Thi...

A greenhouse study was conducted in sand cultures to compare the effects of saline irrigation waters applied by two different methods, flooding and above-canopy sprinkling, on selenium (Se) accumulation by the forage brassicas, kale (Brassica oleracea L., cv. ‘‘Premier’’) and turnip (B. rapa L., cv. ‘‘Forage Star’’). The composition of the irrigation water was designed to simulate saline (7 dS ...
