Neonicotinoid concentrations in arable soils after seed treatment applications in preceding years.
BACKGROUND Concentrations of the neonicotinoid insecticides clothianidin, thiamethoxam and imidacloprid were determined in arable soils from a variety of locations in England. RESULTS In soil samples taken from the central area of fields, concentrations of clothianidin ranged from 0.02 to 13.6 µg kg(-1) . Thiamethoxam concentrations were between <0.02 and 1.50 µg kg(-1) , and imidacloprid con...
متن کاملOrganic Residues A Resource for Arable Soils
Odlare, M. 2005. Organic Residues – a Resource for Arable Soils. Doctor’s dissertation. ISSN 1652-6880, ISBN 91-576-6970-8. An increased recirculation of urban organic residues to arable soils has several environmental benefits, but there is a need for reliable test systems to ensure that soil quality is maintained. In this thesis, soil microbial, chemical and physical properties were included ...

متن کاملHigher diversity of Rhizobium leguminosarum biovar viciae populations in arable soils than in grass soils.
The bacterial genetic diversity after long-term arable cultivation was compared with that under permanent grassland using replicated paired contrasts. Pea-nodulating Rhizobium leguminosarum populations were sampled from pairs of arable and grass sites at four locations in Yorkshire, United Kingdom. Isolates were characterized using both chromosomal (16S-23S ribosomal DNA internal transcribed sp...
متن کاملRing Current Dynamics during the 13–18 July 2000 Storm Period
We study the development of the terrestrial ring current during the time interval of 13–18 July, 2000, which consisted of two small to moderate geomagnetic storms followed by a great storm with indices Dst = −300 nT and Kp = 9. This period of intense geomagnetic activity was caused by three interplanetary coronal mass ejecta (ICME) each driving interplanetary shocks, the last shock being very s...
