Title: Compost and biochar amendments to agricultural soils: Alteration of soil water conditions and organic matter composition
Abstract: This thesis elucidates the influence of urban waste composts and biochar on the water holding capacity and the chemical composition of soil organic carbon. The urban waste composts increased soil carbon contents and stocks of the agricultural soils whereby the clay fraction acted as the main carbon sink. In biochar amended soils this shifted into the particulate organic matter fraction. No amendment affected the quality of the clay fraction. Despite minimal decomposition, biochar was found in all physical fractions after one year in soil. Aged biochar increased the microbial activity and carbon use efficiency under drought stress.
