Application of pig manure increased prokaryotic diversity and altered prokaryotic community structure, while crop residues did not. Soil pH was the predominant factor influencing prokaryotic community structure. Bacillales and Clostridiales accounted for 47.5% and 21.4%, respectively of the indicator species in the IPM and the relative abundances of them were increased, compared with the other treatments. Furthermore, the relative abundances of Bacillales and Clostridiales were correlated with SOC, TN, AP and DOC, and negatively with DC₀ in the soil. Overall, our results suggest that application of NPK fertilizer plus pig manure rather than crop residues enhanced soil pH, improved SOC content and aggregation, increased prokaryotic diversity and altered community structure of prokaryote after 27-year fertilization.]]> Mon 19 Oct 2020 10:43:20 AEDT ]]> Soil organic carbon dynamics: impact of land use changes and management practices: a review https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:37316 Fri 02 Oct 2020 15:25:07 AEST ]]>
