Rainfall exclusion in an eastern Amazonian forest alters soil water movement and depth of water uptake.
Deuterium-labeled water was used to study the effect of the Tapajós Throughfall Exclusion Experiment (TTEE) on soil moisture movement and on depth of water uptake by trees of Coussarea racemosa, Sclerolobium chrysophyllum, and Eschweilera pedicellata. The TTEE simulates an extended dry season in an eastern Amazonian rainforest, a plausible scenario if the El Niño phenomenon changes with climate...
متن کاملValidation of a spatial–temporal soil water movement and plant water uptake model
Management and irrigation of plants increasingly relies on accurate mathematical models for the movement of water within unsaturated soils. Current models often use values for water content and soil parameters that are averaged over the soil profile. However, many applications require models to more accurately represent the soil–plant–atmosphere continuum, in particular, water movement and satu...
متن کاملThe mechanism of soil water movement as inferred from 0 stable isotope studies
The seasonal movement of soil water through a deep vadose zone of a sandy hill was studied in the central part of The Netherlands. The behaviour of soil water was tracked by monitoring soil water fluctuations and changes in the environmental tracer 0 in vertical profiles at test sites with grassland, heathland and forest. In the temperate climate of the study area a soil moisture deficit develo...
متن کاملEvaluating the Capability of the NLEAP Model to Predict the Movement of Moisture and Nitrat Accoumulation in the Soil
The relationship between the accumulation of nitrate in the soil and its concentration in groundwater and in various plant systems is still not fully understood, but it indicates a high correlation between nitrate leaching and environmental and managerial factors. In this study in order to model the movement of nitrate in the soil profile and loss of fertilizer in the root zone using NLEAP GIS ...
متن کاملInfluence of polyacrylamide application to soil on movement of microorganisms in runoff water.
Polyacrylamide (PAM) use in irrigation for erosion control has increased water infiltration and reduced soil erosion. This has improved runoff water quality via lower concentrations of nitrogen, phosphorous, and pesticides, and decreased biological oxygen demand. Since non-toxic high molecular weight anionic PAMs removed clay size sediment particles in flowing water, we hypothesized that PAM wo...
