EFFECT OF SAWDUST ON SPLASH EROSION IN LABORATORY CONDITION

Abstract

Lunt (1955) obtained the bulk density decreased, moisture increased and total nitrogen and organic carbon increased in all treatments amended with wood chips as compared to check plots. Sawdust mulch could increase the soil oxygen diffusion rate, maintain a more uniform soil temperature, reduce the surface crusting and soil bulk density, and increase the aeration porosity and soil moisture (Johnson, 1944; Lareau, 1989; Khan et al, 2000; Tran, 2005). [...]studies on the efficacy of sawdust on changing splash erosion in rangeland condition did not record. [...]this study aimed to determine the efficiency of sawdust with cover 30, 50, 70 and 90 % on splash erosion in laboratory condition.
