: Experiments found that yields for silage maize using meat and bone meal (MBM) were comparable to those treated with traditional mineral NPK.
: The research demonstrates that combining wood ash (as a potassium source) with meat and bone meal (as a nitrogen and phosphorus source) can effectively provide primary nutrients for crops. Combined Waste Resources as NPK Fertiliser
: Using waste products like biogas digestate and wood ash can be an efficient disposal method and an environmentally friendly alternative to mineral fertilizers, especially for acidic soils. Challenges Identified in the Research : Experiments found that yields for silage maize
