Ehh if you are just going to bury it kiln drying wouldn't really be that helpful. Wood in open air will dry out pretty well just sitting for two years. Commercial wood is only really kiln dried so that nobody has to store it for a year or two first and they can sell it before as much of it warps and twists due to being cut while green which makes less of it able to be sold. With a large enough pile, even if it is left uncovered, only the top couple logs or boards will get wet from the rain and if a small percentage of it rots or grows some fungus, well it wasn't there to get built into other things anyways so it doesn't matter.
