Abstract

Infiltration rates were measured for alfalfa, (Medicago saliva L.,
cv. WL514) subjected to treatments where wheel traffic was varied
in terms of area covered and time of application on a Wasco sandy
loam (coarse-loamy, mixed, nonacid thermic Xeric Torriorthent).
Traffic treatments were (i) No-traffic, (ii) Preplant, (iii) Repeated,
and (iv) traffic similar to what a grower would apply. Infiltration
rates increased for all treatments, with increases being 240% for
treatments without harvest traffic and 140% for treatments with harvest
traffic Increases in infiltration were related to decreases in
stand density. Slight packing (traffic) applied before the soil was
flood-irrigated in 1983 increased infiltration rates 20% compared to
flooding loosened soil (no traffic). Harvest traffic resulted in slower
water movement in the soil.
