A by-product of my stump grinding businees is wood chips. The nice part is most of the chips have some dirt mixed in.What I do is spread the mix over the ground about one foot thick and when the
weeds grow through I add another foot of mix. My original concern was the PH but a wise old farmer pointed out to me that the PH will be neutral when the chips are completly composted. My dump truck holds eight yards and some days I make four or five trips. The thing that suprized me the most was how fast the stuff actually decomposes, within a year I can turn it all under and
plant the ground. This fresh soil seems to grow great hay. I try to use a grass, trefoil, clover mix because of the nitrogen fixing of the clover and trefoil. After three years of hay I hope to
plant other crops and rotate my plantings.
My other fertilizer producers are also organic. They take hay and grain in one end and put out round fertilizer balls out the other end. The problem is you have to shovel the stuff out of thier stalls. And
weeds, horse manure sure does give you
weeds.
