- •
Assess the role of soil fungi and bacteria to decomposition of maize residues and macroaggregate formation.
- •
We used PLFA and 13C in specific PLFA.
- •
Amount of and maize-derived C in fungal PLFA correlated with macroaggregate amount.
- •
Quality of plant residues determines composition and activity of the soil microbial biomass.
- •
Fungal activity is of importance in the formation of macroaggregates.
- •
Actinomycetes may take over the role of soil fungi in the decomposition of soil organic matter.
