• Straw retention drives microbial community succession to improve soil C/N cycling: insights from a multi-year rice-based system (2025) · Frontiers in Microbiology · cited 14× · doi

  While long-term straw retention has been shown to improve soil quality and nutrient-use efficiency, the impacts of short-term straw-return treatment on soil quality and the underlying microbiological mechanism of straw in improving soil fertility and nutrient-use efficiency remain unclear.

• Sugarcane Straw Removal and Irrigation System Shape Arbuscular Mycorrhizal Fungi and Rhizosphere Microorganisms in the Cerrado (2026) · Sugar Tech · doi

  The impact of straw removal on soil biological quality is not well understood, particularly in the context of irrigation systems. There is a lack of studies that evaluate the effects of straw removal and irrigation systems on arbuscular mycorrhizal fungi and rhizosphere microorganisms. The study addresses this gap by investigating the interactions between straw removal and irrigation system on soil microorganisms.
