Sprinkler irrigation has been widely used for winter wheat crops in the North China Plain (NCP) to maintain high crop yield and enhance water use efficiency because resources are scarce. Determining accurate evapotranspiration (ETc) coefficient (Kc) of is critical optimizing sprinkler management. In this study, an eddy covariance system was deployed a field measure energy balance components (net radiation Rn, soil heat flux G, sensible H, latent LE) calculate ETc Kc. The growth parameters...
Air velocity (AV) is one of the main environmental factors involved in thermoregulation, especially at high ambient temperatures. To elucidate effect AV on performance and thermoregulation 4- to 7-wk-old broiler chickens, an experiment was conducted using 4 different (0.8, 1.5, 2.0, 3.0 m/s) constant temperatature (35 ± 1.0°C) RH (60 2.5%). BW, feed intake, fecal urinary excretions were monitored individuals used calculate amount energy expended for maintenance. Infrared thermal imaging...
Recent decades have seen significant progress in the genetic selection of fast-growing meat-type broiler chickens. However, fast growth has coincided with inferior development visceral systems, especially cardiovascular organs, contributing to difficulties coping heat stress. Global mean surface temperatures are expected rise during coming years and climate control systems expensive. This situation, where rate production increases on a yearly basis future foresees increasing temperatures,...
Abstract Evaporation from water bodies strongly depends on surface salinity. Spatial variation of salinity saline commonly occurs across diluted buoyant plumes fed by freshwater inflows. Although mainly studied at the pan evaporation scale, effect has not yet been investigated means direct measurement scale natural bodies. The Dead Sea, a large hypersaline lake, is onshore springs that form local plumes, offering unique opportunity to explore this effect. Surface heat fluxes,...
In cotton, an optimal balance between vegetative and reproductive growth will lead to high yields water-use efficiency. Remote sensing estimations of vegetation variables such as crop coefficient (Kc), Leaf Area Index (LAI), height during plant development can improve irrigation management. Optical Synthetic Aperture Radar (SAR) satellite imagery be a useful data source since they provide synoptic cover at fixed time intervals. Furthermore, better capture the spatial variability in field...
The potential to induce improved thermotolerance in broiler chickens is of great importance. Thermal conditioning one the management tools used improve thermotolerance, enabling broilers cope with extreme environmental conditions. This study investigated effects exposing chicks low ambient temperature (Ta) on-chick body (Tb), surface (Ts) temperatures and total sensible heat loss (SHL) by convection radiation from 2 main radiative organs, face legs. At 3, 4, or at both 3 4 d age, were...
Public domain synthetic-aperture radar (SAR) imagery, particularly from Sentinel-1, has widened the scope of day and night vegetation monitoring, even when cloud cover limits optical Earth observation. Yet, it is challenging to combine SAR images acquired at different incidence angles ascending descending orbits because backscatter dependence on angle. This study demonstrates two transformations that facilitate collective use Sentinel-1 regardless acquisition geometry, for agricultural...
Recent advances in remote sensing and machine learning show potential for improving irrigation use efficiency. In this study, two independent methods to determine the dose processing tomatoes were calibrated, validated, tested an experiment. The first method used multispectral imagery acquired from unoccupied aerial vehicle (UAV) estimate FAO-56 crop coefficient, Kc. second artificial neural network (ANN) trained on eddy covariance measurements of latent heat flux meteorological variables a...
Evapotranspiration (ET) is crucial for water resource management, agricultural planning, and understanding land-atmosphere interactions. Numerous approaches are available estimating ET at various spatial temporal scales, including ground-based measurements, mechanistic models, remote sensing. In this study, we aimed to enhance the accuracy applicability of Sentinel (Sen-ET) plugin in diverse field crops Israel. The primary objectives were validate Sen-ET method using eddy covariance (EC)...
Abstract Deviations in the Priestley‐Taylor (PT) coefficient α PT from its accepted 1.26 value are analyzed over large lakes, reservoirs, and wetlands where stomatal or soil controls minimal absent. The data sets feature wide variations water body sizes climatic conditions. Neither surface temperature nor sensible heat flux alone, which proved successful characterizing some crops, explain measured deviations water. It is shown that relative transport efficiency of turbulent vapor key to...
