Processed pig manure to replace mineral fertilizer
As reported by Nutri2Cycle, processing pig manure is gaining increased attention in Europe, especially in areas with large pig manure surpluses (e.g., The Netherlands, Belgium, Germany). Pig manure can be processed into products and become so-called bio-based fertilizers that contain high concentrations of carbon (C), phosphorus (P), potassium (K) and/or nitrogen (N), which are essential elements for plant growth.

Processing pig manure is gaining increased attention in Europe, especially in areas with large pig manure surpluses (e.g., The Netherlands, Belgium, Germany). Pig manure can be processed into products and become so-called bio-based fertilizers that contain high concentrations of carbon (C), phosphorus (P), potassium (K) and/or nitrogen (N), which are essential elements for plant growth. Theoretically, mineral fertilizer can be replaced by these bio-based fertilizers, which contributes to closing the nutrient loop. However, since bio-based fertilizers are recycled from bioactive raw materials, the presence of organic matter, fatty acids and microbes in the final products are inevitable. These trace substances may influence the agronomic efficacy of the products. This study by WUR, Ghent University and ZLTO analyses the effect that different refinement levels of bio-based fertilizers have on potato yield.
