Wouldn't the wood shavings be the same as sawdust? One year I went to a sawmill and carried home buckets of it to put on my garden. My strawberries were beautiful that year! Pure nitrogen.

It's my understanding that nitrogen would be tied up for a while as it is needed for the shavings or sawdust to be broken down, then released into the soil when that process is over. Sawdust only contains 1% or less of nitrogen. Your bountiful crop might have been the result of the water holding ability of the soil or the ability of the roots to penetrate into the soil more easily. My current soil problem is the result of too much nitrogen so I am trying to neutralize it.
