Micrometeorological and hydrological measurements were made over one growing season using automatic weather stations and weighing lysimeters at several locations within a multiple land-use agricultural catchment in Southern Ontario. This paper compares modelled potential evapotranspiration (PET) and measured actual evapotranspi-5 ration (AET) values obtained from the soil weighing lysimeters, a...

The impact of climate variability on the water cycle in desert ecosystems is controlled by biospheric feedback at interannual to millennial timescales. This paper describes a unique field dataset from weighing lysimeters beneath nonvegetated and vegetated systems that unequivocally demonstrates the role of vegetation dynamics in controlling water cycle response to interannual climate variabilit...

Many greenkeepers and authorities are concerned about the environmental risks resulting from pesticide use on golf courses. We studied leaching surface runoff of fungicides metabolites for two winter seasons after fall application boscalid, pyraclostrobin, prothioconazole, trifloxystrobin, fludioxonil in field lysimeters at NIBIO Landvik, Norway. The applications were made creeping bentgrass gr...

ABSTRACT Yellow passion fruit is a species widely cultivated throughout the Brazilian semi-arid territory, but its yield affected by quality of waters this region. In context, objective was to evaluate gas exchange and production cv. BRS Rubi do Cerrado irrigated with different cationic natures. The study conducted in drainage lysimeters under greenhouse conditions Campina Grande, PB, Brazil, r...

Abstract. Water fluxes at the soil–atmosphere interface are a key piece of information for studying terrestrial water cycle. However, measuring and modeling in vadose zone poses great challenges. While direct measurements require costly lysimeters, common soil hydrologic models rely on correct parametrization, representation involved processes, selection initial boundary conditions. In contrast...

The Bowen ratio-energy balance (BREB) is a micrometeorological method often used to estimate latent heat flux because of its simplicity, robustness, and cost. Estimates of latent heat flux have compared favorably with other methods in several studies, but other studies have been less certain, especially when there was sensible heat advection. We compared the latent heat flux of irrigated alfalf...
