Waste products as alternative phosphorus fertilisers part I: inorganic P species affect fertilisation effects depending on soil pH

Kategori: Fosfor, Gjødsel, Næringsstoffer

One of the bottlenecks to efficient phosphorus (P) recycling is limited understanding of the relationships between inorganic P species in waste products and their P fertilisation effects. In this study, we characterised inorganic P species in seven waste products (two biomass ashes, meat bone meal, fish sludge, catering waste and two food waste-based digestate products) and two manure products (dairy and chicken manure) by: (1) Sequential chemical fractionation, (2) X-ray powder diffraction and (3) solid-state 31P MAS-NMR spectroscopy.
