Abstract
Afield study was carried out to determine the effect of machinery compaction and tillage systems on infiltration rate of sandy soils. Mean cumulative infiltration of soils was 5.12 cm h
-1
for rotary plow and 7.22 cm h
-1
for chisel plow treatments, whereas the mean infiltration rate of soils was 6.95 and 10.30 cm h
-1
for rotary and chisel plow treatments, respectively. Among the different compaction treatments, two-pass treatment caused 13 and 42% reduction in infiltration rate of soil under rotary and chisel plow, respectively. The difference in infiltration rate of soils between two-and three-pass treatments was significant. This study has indicated a potential for water conservation in sandy soils if simple conventional agricultural implements are used for soil compaction.
