“…Field boundaries represent physical barri ers that interrupt soil flux by tillage (Papendick and Miller, 1977;Dabney et al, 1999;Van Oost et al, 2000a). These lines of zero flux produce a net soil accumulation on the upslope side or a net soil loss on the lower slope side.…”

Tillage erosion has been identified as an irrportantglobal soil degradation process that has to be accounted for when assessing the erosional irrpacts on soil productivit;l, environmental quality or landscape evolution. In this paper, we present a summary of available data describing tillage erosion. This provides insights in the controlling factors determining soil redistribution rates and patterns by tillage for various irrplements used in both mechanized and non-mechanized agriculture.Variations in tillage depth and tillage direction cause the largest variations in soil redistribution rates, although other factors, such as tillage speed and irrplement maracteristics, also play an important role. In general, decreasing tillage depth and ploughing along the contour lines substantially reduce tillage erosion rates and can be considered as effective soil conservation strategies. Implement erosivities reported in literature, characterized by the tillage transport coeffi cient, are very consistent and range in the order of 400--800 kg m-1yr-1 and 70-260 kg m-1yr-1 for mechanized and non mechanized agriculture, respectively. Comparison of tillage erosion rates with water erosion rates using a global data set indicates that tillage erosion rates are at least in the same order of magnitude or higher than water erosion rates, in almost all cases. Finally, we discuss how tillage erosion increases the spatial variability of soil properties and aff ects soil nutrient cycling. Considering the widespread use of tillage practices, the high redistribution rates associated with the process and its direct effect on soil properties, it is clear that tillage erosion should be considered in soil landscape studies.

Danilo Godone holds a PhD in "Agriculture, Forest and Food Sciences", doctorate's topic was cryosphere's phenomena monitoring by geomatic methodologies. Currently he is a PostDoc grant holder, at Turin University, studying geomatic contribution in land management and analysis. His main research interests are, however, landslide, glacier and, more generally, natural disasters monitoring. During his activities he has developed skills in GIS, also by developing customised tools by Visual Basic programming, and land surveying with GPS or Laser Scanners. He is a member of NATRISK -Research Centre on Natural Risks in Mountain and Hilly Environments, in the same University. He acts as a freelance consultant, in the same topics, for other research bodies, training agencies and professionals, too.Dr. Silvia Stanchi holds a PhD in "Agriculture, Forest and Food Sciences", with a focus on fractal theory approaches for the study of soil aggregation and structure. Currently, she is a PostDoc at Turin University working on soil hazards and vulnerability in mountain areas.

Effectiveness of vegetation barriers for marly sediment trapping

Vegetation barriers can be effective in trapping eroded sediment, but little knowledge exists on the characteristics of vegetation barriers efficient in trapping all sediments from an eroded zone upslope. The objective of this study is to quantify the effectiveness of vegetation barriers for marly sediment trapping. Relationships between eroded zones and vegetation barriers -composed of low vegetation, that is to say herbaceous and under-shrub layers -located downslope and sufficient to stop all the sediments eroded above, have been studied in the Brusquet experimental marly catchment in the French southern Alps. Forty plots with surface areas less than 500 m 2 were studied. The eroded zones and the vegetation barriers were characterized by their surface areas, between which an average linear relationship exists. Results also showed that, for a marly plot with a given surface area, a downslope vegetation barrier covering only 20 per cent of this plot can be sufficient to trap all the sediments eroded above it.
