The partitioning of bulk precipitation (PR) in forest ecosystems and its chemical composition depends on both meteorological factors, such as amount intensity, evaporation rate, wind speed, stand structural density, canopy structure, bark texture, spatiotemporal distribution density foliage. We analysed fluxes water element contained therein a mature European beech (Fagus sylvatica L.) sandy so...

Rigorous studies on long-term changes of heavy metal distribution in forest soils since the implementation of emission controls are rare. Hence, we resampled 97 old-growth beech stands in the Vienna Woods. This study exploits an extensive data set of soil (infiltration zone of stemflow and between trees area) and foliar chemistry from three decades ago. It was hypothesized that declining deposi...

As a raindrop falls from the atmosphere, over vegetation and forest canopies, and enters soils and streams it experiences a dynamic exchange of carbon constituents with the surrounding environment. Understanding the magnitude and dynamics of carbon export in above and below ground flow paths is critical for constraining the influence of terrestrial and aquatic ecosystems on global carbon cyclin...

Stemflow can be an important pathway for the drainage of precipitation and related solutes through tree canopies to forest soils. As stemflow must drain along bark surfaces, effects structure on chemical composition is merited. This study examines relationship between chemistry surface six species varying morphology (four deciduous broadleaf trees two evergreen coniferous trees) at a montane ur...

Throughfall was measured for a year at five-min intervals in 11 collectors randomly located on two plots in a second-growth redwood forest at the Caspar Creek Experimental Watersheds. Monitoring at one plot continued two more years, during which stemflow from 24 trees was also measured. Comparison of throughfall and stemflow to rainfall measured in adjacent clearings indicates throughfall and s...

Rigorous studies of recovery from soil acidification are rare. Hence, we resampled 97 old-growth beech stands in the Vienna Woods. This study exploits an extensive data set of soil (infiltration zone of stemflow and between trees area at different soil depths) and foliar chemistry from three decades ago. It was hypothesized that declining acidic deposition is reflected in soil and foliar chemis...

recently, the most important topic in water management was to determine the effects of urban forests and green space on partitioning gross rainfall (gr) into the rainfall interception (i), stemflow (sf), and throughfall (tf). the main aim of this research was to quantify the seasonal variations [growing season (gs), and non-growing season (ngs)]) in i by individual fraxinus rotundifolia trees i...

A systematic collection of throughfall (rain passing through the canopies), stemflow (rain flowing over the stems), and soil percolates was carried out in a Acacia dealbata plantation during one year, and its allelopathic capacity was biotested using Lactuca sativa L. var. Great Lakes. The results showed an allelopathic effect related to flowers: Germination of L. sativa was inhibited 30% by th...

Vegetation cover plays an essential role in the vertical and horizontal distribution of rainwater. As rainwater passes through canopy, it can be divided into interception loss, throughfall, stemflow. In areas where yerba mate is cultivated, loss influences variability water reaching soil, surface runoff, nutrient cycling. The objective this study was to evaluate stemflow, ( Iex paraguariensis )...

Stemflow is vital for supplying water, fertilizer, and other crop essentials during sprinkler irrigation. Exploring the spatial temporal variations of stemflow its influencing factors will be essential to preventing soil water nutrient ion’s migration deeper layers, developing, optimizing effective irrigation schedules. Based on two-year experimental data, we analyzed variation patterns (stemfl...
