In this work TF values for Sr and Cs were measured for reference plants grown in lysimeters containing soils representative of large agricultural areas in Brazil: Ferralsol, Nitisol and Acrisol. These results were discussed in the light of pedological analyses and results from the follow sequential chemical extraction protocol: 1) slightly acidic phase containing readily bioavailable elements; ...

The calculation of evapotranspiration and its components transpiration and evapotranspiration is of crucial importance in dynamic crop-weather models, irrigation models and SVAT models. Although many approaches were developed and adapted for various applications and based on available input data, there is still a remarkable range of uncertainty related for a representative calculation. However,...

Abstract This study investigates the contamination potential of herbicides to groundwater with help numerical modeling (HYDRUS‐1D) and stable carbon isotopes for characterizing biodegradation. Four herbicides, metolachlor, terbuthylazine, prosulfuron, nicosulfuron, were applied over a period 4.5 years on two lysimeters located in Wielenbach, Germany, monitored by lysimeter drainage. These conta...

The growth and biomass production by willow (Salix viminalis L.) was studied in lysimeters containing Oxford clay landfill cap soil with different amendments, bulk densities and watering regimes. Three years from planting, stem biomass in well-watered plants was least (0.28 kg plant(-1)) with high bulk density soil (1480 kg m(-3)) and no nutritional amendment but was increased 10-fold (2.53 kg ...
