Abstract

Biochar research has focused in the last years in the use of wood or grass derived materials for carbon sequestration. However, manure derived biochar can provide other benefits after soil addition, including nutrient supply. At present, there is an incomplete understanding of pyrolysis on manures. In order to understand the benefits obtained after addition of these types of materials to the soil, an experiment involving the use of different manures and pyrolysis temperatures was performed. Five manure wastes were selected for this experiment: cattle manure (E); cattle manure mixed with straw (EP), chicken manure (G), chicken manure mixed with sawdust (GS) and pig slurry (PC). Unpyrolyzed samples were compared to biochars prepared at 300 and 500?C. Relevant properties for agronomic purposes were determined, including pH, electrical conductivity, nutrient content, metal content, proximate analysis and carbon thermostability. Our results show that biochars tailored for different purposes can be prepared after a careful choice of feedstock and pyrolysis temperature.
