Sustainable Fertilizer from slaughterhouse digested sludge

This dataset contains data related to the evaluation of the fertilizing potential of a dried anaerobic digestate produced from slaughterhouse residues, generated in the framework of the “Sustainable fertilizers” EIT FOOD project. The fertilizing potential was assessed through a short-term (42 days) soil incubation experiment using two different soils, Clay-Loam cambisol soil (CC) and Fulvic cambisol soil (FC). The effect of the dried anaerobic digestate (DD) application was compared with other fertilizers: i) diammonium phosphate (MIN); ii) digested manure (DM); iii) cattle manure (CM), and a negative control as unfertilized soil (CTR). Each fertilizer was added to each soil in a dose of 100 mgN/kg of dry soil. During the incubation period, ammonium-nitrogen, nitrate/nitrite-nitrogen and phosphorus release were monitored. At the end of the incubation, biochemical (extractable carbon and nitrogen, microbial biomass carbon, enzyme activities) and chemical (pH, electric conductivity, exchangeable Mg, K and Ca) were assessed. Moreover, community level physiological profiling (CLPP) analysis was performed through Biolog® with ECO-plates.
