Fate of atrazine in sandy soil cropped with sorghum.
A field study was conducted to determine the fate of atrazine (6-chloro-N2-ethyl-N4-isopropyl-1,3,5-triazine-2,4-diamine) within the root zone (0 to 90 cm) of a sandy soil cropped with sorghum [Sorghum bicolor (L.) Moench] in Gainesville, Florida. Atrazine was uniformly applied at a rate of 1.12 kg ai. ha(-1) to a sorghum crop under moderate irrigation, optimum irrigation, and no irrigation (ra...
متن کاملMossbauer Study of the Attenuation of Iron in an Irrigated Greensand Lysimeter
-Fe 57 Mfssbauer spectroscopy has been used to determine the nature of iron-containing minerals in Lower Greensand samples from an experimental lysimeter at Uffington, Oxfordshire, both before and after a three-year irrigation with a synthetic heavy metal leachate. Analysis of the spectra measured at 300 ~ 77 ~ and 4.2~ and at 4.2~ in an applied field of 45 kOe shows that iron is present in the...
متن کاملLysimeter experiments with metolachlor in Tor Mancina (Italy)
The paper describes one of the four datasets used to test pesticide leaching models within the Working Group Modelling of the EC European Program COST Action 66 `Fate of Pesticides in the Soil and the Environment'. The Tor Mancina dataset is the result of a 3-year lysimeter experiment carried out near Rome (Italy) on a clay-loam calcareous ̄uvisol, which aimed to asses the risk of groundwater c...
متن کاملThe Fate of Herbicides in Soil
The agrochemical spreading is a common and essential agricoltural practice to obtain high quality, large harvests. Agrochemicals are classified according to the target organisms designed to be controlled (insects, weeds, fungi). Of all the target organisms, weeds cause by far the greatest economic loss due to their interference in crop production. It is not surprising therefore, that herbicides...
متن کاملEcotoxicity and fate of a silver nanomaterial in an outdoor lysimeter study
Sewage sludge is repeatedly applied as fertilizer on farmland due to its high nutrient content. This may lead to a significant increase of silver nanomaterials (AgNM) in soil over years. Therefore, our aim was to investigate the ecotoxicity and fate of AgNM under environmentally relevant conditions in outdoor lysimeters over 25 months. Two AgNM concentrations (1.7 and 8.0 mg/kg dry matter soil)...
