Long-term effects of straw return and straw-derived biochar amendment on bacterial communities in soil aggregates [PDF]

Scientific Reports, 2020
AbstractImproving soil structure, fertility, and production is of major concern for establishing sustainable agroecosystems. Further research is needed to evaluate whether different methods of straw returning determine the variations of soil aggregation and the microbial community in aggregates in the long term.
