Research Abstract

We analyzed soil biodiversity and functioning in forest and cropland soils to establish a sustainable land use. Forest management did not change soil community and structure, while fine particles and microaggregates increased with forest age. Cultivation of soil in cropland was detrimental to soil biodiversity and aggregates. However, no tillage with weed introduction increased soil sequestration in a short time periods. We conclude that soil aggregates which are formed by biological activities is important index for soil fuction.
