Infiltrability of this experimental site was lower than that of the undisturbed secondary forest reported by Moormann et al. [1975]. The analysis of variance of "F' ratio for cumulative infiltration is shown in Table 2. The cumulative infiltration (I) for different treatments are shown for 10 and 20 min, in Table 3, 30 and 45 min in Table 4, 60 and 90 min in Table 5 and
for 120 min in Table 6. There were significant differences among treatments even one year after initiating the project. One year after cultivation began, both 10- and 20-min cumulative infiltration were the highest for Leucaena based systems.
