Sooby , if you have to buy nitrogen to add to the soil to replace the nitrogen removed by the decomposing wood chips/fines ......what is the point ? I could see having the fines decomposing in a compost heap until ready to use but still makes no sense to me to have to spend money on the fines and then money on the nitrogen needed to add in to replace the nitrogen used by the decomposing fines . Why not just use compost ?
