The hormone 17beta-estradiol (E2) can cause endocrine disruption in sensitive species at part per trillion concentrations. The persistence and transport pathways of manure-borne E2 in agricultural soils were determined by comparing its occurrence with the transfer of water and the transport of non-sorbing fluorobenzoic acid (FBA) tracers. This comparison was done using capillary wick lysimeters...

Given the water scarcity becoming endemic to a large portion of the globe, arid region irrigation has resorted to the use of treated, partially treated, or even untreated wastewaters. Such waters contain a number of pollutants, including surfactants. Applied to agricultural lands, these surfactants could affect the fate and transport of other chemicals in the soil, particularly pesticides. A fi...

The lowlands in northeast Germany are among the driest and at the same time the most densely wooded regions in Germany. Low annual precipitation between 500 and 600 mm and the light sandy soils with their low water storage capacity and high porosity lead to limited water availability. Therefore the hydrological functions of forests play an important role in the fields of regional water budget, ...

The progress made in developing information and communication technologies (ICTs) the fact that water resources are becoming increasingly scarce make precision agriculture a very valuable tool for efficient sustainable crop management, particularly irrigation fertilisation. In line with this, balance estimate is considered one of most accurate methods estimating crops’ requirements. Agromotic E...

Original scientific paper In this paper a numerical model was used to evaluate water flow in free drainage lysimeters with respect to soil anisotropy (hydraulic conductivity). Lysimeters were installed in undisturbed soil profile on two soil types with different anisotropy (low and high). The soil types were classified as Luvic Stagnic Phaeozem Siltic and Haplic Gleysol Calcaric Eutric Siltic. ...

Soil microorganisms colonizing soil water sampling devices (lysimeters) reduced concentrations of biodegradable organic chemicals, including 2,4-dichlorophenoxyacetic acid methyl ester, alachlor, methyl m-chlorobenzoate, and metolachlor as water entered through porous ceramic cups. In some cases, losses exceeded 99%. Additions of either a biocide (sodium hypochlorite) or a bacteriostat (copper ...

Preferential and lateral subsurface flow (LSF) may be responsible for the accelerated transport of water solutes in sloping agricultural landscapes; however, process is difficult to observe. One idea compare time series soil moisture observations field with those lysimeters, where vertically oriented. This study aims at identifying periods deviations contents pressure heads measured a weighing ...

Rain gardens are increasing in use as the shift from gray to green infrastructure continues. Water that enters a rain garden is removed by three mechanisms: overflow an outlet, percolation underlying soil, and evapotranspiration (ET) atmosphere. Despite importance of ET aiding recover void space during time between storm events, it not often measured or calculated because so difficult do so. Th...

Considering profitability in pasture-based systems, investigating parameters affecting crop coefficients for irrigation management becomes important. In this experiment, we determined the coefficient of ‘Marandu’ palisadegrass based on accumulated degree-days and estimated plant water consumption under single (‘Marandu’ alisadegrass) mixed + black oats Italian ryegrass) cropping regimes. The re...
