George,
I use dirt from the garden, as said previously microwave it to kill any thing in it. Then I let it dry completely. when dry sieve it to remove larger items. But keep them in a separate pot. when you have nothing but fine dust add this to a separate pot. any very small bits of vegetation I keep as well. Next make a slurry with the earth, dry filler and white glue, don't make it to wet then apply to the base let it dry for a while then lay some cling film over it and press the vehicle into it and using spare pieces of track or wheels press these in as well this should give you a good simulation of traffic and stop your vehicle sitting on top.
here is an example of mud I created a while ago. HTH.
