To the best of our knowledge, this is the
first study to
comprehensively evaluate the effects of pig manure organic–
inorganic compound fertilizer with reduced chemical fertilizer on
crop yields, soil edaphic properties, biological attributes (microbial
biomass and enzyme activity), biochemical traits (microbial
nitrogen functional genes), and the bacterial community structure
in a rice–wheat cropping system under the
field conditions. The
NPKMOI treatment was able to increase crop yields, soil nutrient
availability, microbial biomass, enzymatic activity, nitrogen
processes, community richness and diversity. Therefore, the
NPKMOI treatment might be a sound fertilization practice for
the sustainable food production in the future
