Mechanical site preparation methods that used tools mounted on lightweight excavators and provided localised intensive were tested in eight experimental sites across France where the vegetation was dominated either by (L.) Moench or Kuhn. Two (Deep Scarifier: DS; Deep Scarifier followed Multifunction Subsoiler: DS+MS) pine ( L., var. (Loudon) Hyl. Aiton) oak (Matt.) Liebl. L.) plantations...

Understanding the roles of natural drivers in greenhouse gas (GHG) emissions arable fields is crucial for adequate agricultural management. This study investigated combined effect two tillage treatments (NT - no-tillage; CT with mouldboard ploughing) and environmental (air pressure, air temperature) soil factors (total organic carbon, gravimetric water content penetration resistance) on carbon ...

To reduce muddy ̄ooding in northern France, where soils are typically silty and highly sensitive to crusting, it is necessary to decrease the volumes of sediment-laden runoff coming from upslope agricultural source areas. To investigate the consequences of upslope agricultural practices on downslope muddy ̄ooding, we compared the effects of no-tillage treatment (NT), light-duty mouldboard ploug...

The domestication of sheep, goats and cattle by the first farmers of the Fertile Crescent of western Asia, some ten thousand years ago, had unexpected consequences. Originally intended simply to secure for sedentary cerealcultivators a captive meat supply and a convenient source of materials such as sinew and horn, domesticated livestock came to provide novel services to human populations in li...

dryland winter wheat (triticum sativum l.) generally grown in rotation with fallow or chickpea (cicer arietinum l.) constitutes a major crop in the west region of iran. information is limited on the success of more intensive dryland cropping systems while applying conservation tillage management. an experiment was conducted to determine the effect of five tillage systems on soil physical proper...

Tillage practices and weather affect the release of greenhouse gases but there have been few integrated studies of the quantities released or the mechanisms involved. No-tillage may increase emissions of nitrous oxide (N2O) and the ®xation of carbon by decreasing carbon dioxide (CO2) emissions. Tillage may also decrease the oxidation rate of atmospheric methane (CH4) in aerobic soil. These effe...
