, with duplicate treatments :(1) bare soil; (2) permanent grass; (3) bare soil with 1 m Borassus-mat buffer zones at the lower end of the plots; (4) bare soil with 1 m Buriti-mat buffer zones at the lower end of the plots; and (5) completely-covered with Borassus

Field experiments were conducted at Hilton, east Shropshire, U.K. during 2007–2009, to study the impacts of Borassus and Buriti mats on selected properties of the topsoil. Ten fixed plots were established, with duplicate treatments : (i) bare soil
; (ii) permanent grassed; (iii) bare soil with 1 m Borassus-mat buffer strips at the lower end of the plots; (iv) bare soil with 1 m Buriti mat buffer strips at the lower end of the plots; and (v) completely-covered with Borassus mats. Initial and final

to be the most important variables in reducing SLR (ratio of soil loss in bare plots to that in geotextile treated plots) for splash, C (%) for interrill and D (min) for rill and interrill erosion processes, respectively. Soil clay and silt contents and D are key
variables in decreasing RR (ratio of runoff from bare plots to that from geotextile treated plots) for interrill, and clay content for rill and interrill erosion processes, respectively.

and soil erosion. Although buffer strips of Borassus mats were as effective as whole plot cover of the same mats, the longevity of Borassus mats was nearly twice that of Buriti mats. Thus, use of Borassus mats as buffer strips on bare plots is highly
