Composting of Dairy Manure and Grape Vine Prunings as a Tool to Better Manage Both Industries Waste and Reduce Their Environmental Impact

Why Look at Grapevine Prunings As a Compost Feedstock?

The objectives of this research and Extension project were:

  • To determine the impact of mixing grape vine prunings with dairy manure in a compost mix on the composting process and final product.
  • In particular, we were interested in determining if nitrogen gets fixated into the compost mix with increased carbon content.
