The use of plastic sheet in soil erosion and conservation studies

, : The use of plastic sheet in soil erosion and conservation studies. Erosion, conservation, and small scale farming: 471-475

Use of plastic sheet to line ponds below runoff plots is proposed as a simple field method of assessing sediment loss from plots. The method is described for plots in Chiangrai Province, Thailand, where conservation measures were employed on reddish brown lateritic soil on a 40% slope. 2.1 t/ha and 71 t/ha soil loss was measured from grass stripped and control plots respectively.
