: Experiments found that yields for silage maize using meat and bone meal (MBM) were comparable to those treated with traditional mineral NPK.
Waste-Derived Fertilizers: Conversion Technologies, Circular ... - MDPI 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
: 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
