Kaye, if the tractor tires compressed the soil over the leach field so that septic tank effluent pools in the ruts and is exposed to the atmosphere, then fill in the ruts with soil. The odorous hydrogen sulfide gas being released from the septic tank effluent will be eliminated (oxidized) by the oxygen in the air between the soil pores.
