Report on the Chemical Quality of Different Types of Manure (Processed and Unprocessed) Including P Solubility

The application of manure and manure-based products on agricultural soil must comply with the codes of Good Agricultural Practice. Fertiliser rates are ideally purely demand-driven. In addition, putative contamination with inorganic and organic pollutants needs to be taken into account and evaluated. This report characterises the elemental composition, P-solubility and heavy metal content of manure and manure-based fertilisers. The report summarises the effect of animal species, type of manure (slurry or solid) and processing of manure on the composition of fertiliser products.


The chemical analysis revealed a heterogeneity of the products which is typical of manure. In general, the total P content varied between 0.1 and 1.1% (of dry matter) and the heavy metal content was low. Only gasified pig manure had a much higher total P content (3.9% of dry matter), but also the lowest P availability. The P availability of manure ranged from 60 to 90% (of total P) in relation to manure type and extraction method.


This report on the chemical quality of different manure types was prepared as part of work package 4 on manure standards in the project Baltic Manure.
