Biochar is suggested for soil amelioration and carbon sequestration, based on its assumed role as the key factor for the long-term fertility of Terra preta soils. Several studies have shown that certain biochar properties can undergo changes through ageing processes, especially regarding charge characteristics. However, only a few studies determined the changes of different biochars under the same...
In soils, dissolved organic matter (DOM) is probably the most bioavailable fraction of soil organic matter, since all microbial uptake mechanisms require a water environment. Bioavailability describes the potential of microorganisms to interact with DOM. It is a prerequisite for biodegradation and can be restricted, if DOM is present in small pores or within soil aggregates and therefore not accessible...
Composting of municipal biowaste in the presence of 14 C-labelled organic contaminants was studied in an attempt to characterize the mobilization potential of dissolved organic matter (DOM) for hydrophobic contaminants. The properties and transformation of DOM extracted from municipal biowaste compost with 10 mM KCl at six stages during 370 days of composting were investigated. DOM was...
