Using palm-mat geotextiles for soil conservation : II. Effects on in situ soil particle size distribution and nutrient concentration

Auteur(s) et Affiliation(s)



Description :
Field experiments were conducted at Hilton, east Shropshire, U.K. during 2007-2009, to study the impacts of palm-mat geotextiles on topsoil particle size distribution and changes in selected nutrients (total P, K, Ca, Mg, S, Zn, Cu, Fe, Mn, Mo and Cl). Geotextile-mats constructed from Borassus aethiopum (Borassus palm of West Africa) and Mauritia flexuosa (Buriti palm of South America) leaves are termed Borassus mats and Buriti mats, respectively. Ten runoff plots were established, 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 mats. The AA. conclude that despite significant (P < 0.05) decreases in soil clay and total Ca contents, use of Borassus mats as buffer strips was very successful in conserving or improving other selected soil properties.
