• Fungal community structure from maize rhizosphere in different straw returning modes (2026) · Journal of King Saud University – Science · doi

  The study identifies a gap in understanding the effects of different straw returning modes on maize rhizosphere fungal communities. The paper notes that straw returning is an effective measure of conservation tillage, but its impact on soil fungal communities is not well understood. The study aims to fill this gap by investigating the effects of different straw returning modes on fungal community structure and function.
