PhD defence: Is the decomposition of tea bags affected by long-term manure application and crop rotation?

During her PhD studies, Yuting Fu researched the effect of manure and crop rotation on soil physical, chemical and microbiological properties, and how these modified soil properties control the decomposition of tea bags in seven long-term experimental sites in Europe.

Tuesday 21 March 2023,  at 10:00 - 13:00

The sites encompassed different soil and crop types, and the role of these variables was also investigated.

Soil texture played a primary role in the initial decomposition of tea bags, followed by the management. The research findings contribute to our understanding of how agricultural managements affect the decomposition of organic materials. The findings can further contribute to the estimation of carbon sequestration for different agricultural practices under different soil textures.

The PhD study was completed at the Department of Agroecology, Faculty of Technical Sciences, Aarhus University.
