Abstract:
The paper summarizes results of investigations done in
1999–2000 by several authors in Wielkopolska region, (western Poland) near
Turew in young midfield shelterbelts and adjacent cereal fields. It was found
that the soil organic matter content, as well as microbial and faunal biomass
decrease gradually from the shelterbelt toward the field centre. The annual
increase of carbon was assessed and possible sources of it (wind erosion,
leaf fall, input of invertebrate faeces) considered. The results suggest,
that excreta contribute significantly to total carbon input. The shelterbelts
influence the biomass, density and composition of many soil and above-ground
taxa and individual size of animals occurring in bordering fields. |
