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...

Reduction of migration of fecal coliforms (FC) and streptococci (FS) by limiting the leaching in effluent-irrigated soil was tested in lysimeters packed with quartz sand without or with added biosolids compost or with one of two clayey soils. The 200-L, 70-cm-deep lysimeters were either planted with a Eucalyptus camaldulensis or an Oroblanco citrus tree (in the sand only), or not planted. The E...

this study was undertaken to investigate the feasibility of treating industrial wastewater using soil and plant system. nine cylindrical plastic-lysimeters (60 cm diameter and 100 cm height) equipped with a drain pipe at the bottom were filled by granular sandy-loam soil. sunflower, oat and fescue were planted each in three lysimeters, in order to investigate the effectiveness of plants in lead...

The increasing demands for environmental protection and sustainable food production require an increase in the use of natural and non-toxic materials for agriculture. In this study, the feasibility of using surfactant-modified zeolite (SMZ) in comparison with zeolite clinoptilolite (Cp) application to reduce nitrate leaching and enhance crop growth was investigated. The effects of size (millime...

Evapotranspiration (E,) was estimated for plant, first ratoon and second ratoon crops in a sugarcane field by means of the water balance in a large plastic-lined lysimeter (405 m2) and three small weighed lysimeters (each 3,71 m2). For the first 230 days of the plant crop of the experiment the mean daily estimates of E , from the large and small lysimeters were 4,14 mm and 4,16 mm respectively....

The main physical and chemical controls on nitrogen (N) fluxes between the root zone and the water table were determined for agricultural sites in California, Indiana, Maryland, Nebraska, and Washington from 2004 to 2005. Sites included irrigated and nonirrigated fields; soil textures ranging from clay to sand; crops including corn, soybeans, almonds, and pasture; and unsaturated zone thickness...

Data for water vapor adsorption and evaporation are presented for a bare soil (sandy loam, clay content 15%) in a southern Spanish olive grove. Water losses and gains were measured using eight high-precision minilysimeters, placed around an olive tree, which had been irrigated until the soil reached field capacity (!0.22 m m). They were subsequently left to dry for 10 days. A pair of lysimeters...

Plant growth largely depends on microbial community structure and function in the rhizosphere. In turn, microbial communities in the rhizosphere rely on carbohydrates provided by the host plant. This paper presents the first study on ozone effects in the plant-rhizosphere-bulk soil system of 4-year-old beech trees using outdoor lysimeters as a research platform. The lysimeters were filled with ...

ABSTRACT Scarcity of good quality water is a limiting factor for irrigated agriculture, especially in semi-arid regions, which induces the use waters with high salt concentration crop irrigation. In view above, objective this study was to evaluate phytomass accumulation and production components colored cotton genotypes during different development stages, under conditions salinity, plants grow...

The goal of the European Nitrate Directive 91/676/CEE is to mitigate or prevent water pollution associated with nitrogen (N) cascade. Vegetable crops have a high risk nitrate leaching during autumn and winter. Information about fate N from artichoke (Cynara cardunculus L. var. scolymus (L.)) residues reviewed then supplemented three-year study 15N-labelled in an artichoke-cauliflower (Brassica ...
