That will sure be some rich soil once it all composts! Do you plant crops for the pigs? I'm thinking turnips.The mud in a 16x16 piglet pen turned an entire round hay bale into decayed mud slush! So I dumped about 8 yards of tree branch mulch on the slush yesterday. Then a thick layer of last years hay. The mulch is an excellent barrier to keep the hay from mud contact and speeding up the decay.
Of course pigs like to till it up. Just got to feed them at free will to keep them with full bellies and too stuffed to search for what not under the hay!
