: Experiments found that yields for silage maize using meat and bone meal (MBM) were comparable to those treated with traditional mineral NPK.
: Beyond just adding NPK, these combined waste resources provide organic matter that improves soil structure, microbial diversity, and water retention—benefits that synthetic fertilizers lack. Combined Waste Resources as NPK Fertiliser
The research titled primarily refers to the work of researcher Eva Martina Brod from the Department of Plant and Environmental Sciences at the Norwegian University of Life Sciences . Her work, specifically in her master's thesis and subsequent publications, explores how different waste streams can be blended to create effective recycled fertilizers. Core Findings & Effectiveness : Experiments found that yields for silage maize
: 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 Her work, specifically in her master's thesis and
: 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.
