摘要：

The present paper deals with the long-term effects of bare fallow and organic treatments on soil aggregate stability. Soil samples were collected from plots of the long-term soil organic matter experiment in Ultuina/Sweden, which is already running for 38 years. Soil aggregate stability (SAS) showed a clear response to soil management. SAS increased in following order: bare fallow < no-N < green manure < peat less than or equal to farmyard manure. Humus contents of the plots had a significant impact on SAS. Incfeasing C-org-contents generally enhanced aggregation. However, the unfavourably high C/N ratio of peat treatments and the resulting small size of microbial biomass led to a distinctly lower positive influence of accumulated soil organic matter in case of peat additions.
