- •
We tested the effects of straw addition and DRW on microbial community and aggregation.
- •
Straw improved soil aggregation and microbial community resistance to drought.
- •
Straw addition increased hydrolase activities and their resilience after rewetting.
- •
Post-rewetting nutrient acquisition drove colonization of heterotrophic communities.
- •
Straw amendment favored soil functional stability during drying and rewetting.
