Abstract

Short term changes (5 years) of water infiltration in a clay soil were studied under protection from grazing vs. grazed conditions. Infiltration experiments, using rainfall simulating INFILTRAMETER (Meeuwig, modified form) inside and outside 8 randomly selected exclusures from among 96, were conducted. Infiltration depth indices were measured on experimental plots during 1988. On the basis of KOSTIAKOV EQUATION, regression analysis on collected data was performed equation coefficients for instantaneous, cumulative, and hnal INFILTRATION RATEs, being computed. The results indicated that instantaneous and final INFILTRATION RATEs had increased in protected areas, in grazed as well as in two sites outside exclusures No. 65 and 41. Increasing instantaneous and final INFILTRATION RATEs in grazed sites on vegetation type 4 (fig.1), was due to crust breaking through trampling, increased density of annual grasses, annual and perennial forbs as well as more rocks and pavement cover. Increased INFILTRATION RATE in grazed site on vegetation type 6 (fig.1) was mainly related to grazing protection by rural community during the experimental years. Comparing to protected site in this site canopy cover of perennial forbs increased inside exclusure. On the average, final INFILTRATION RATE in 8 vegetation types under protection from grazing increased 54.1 percent (2.09 cm/hr). Correlation coefficients between final INFILTRATION RATE, canopy cover and litter were 0.70 and 0.67 respectively (%5 significant level).
