چکیده انگلیسی
Factorial ANOVA on 13CCr revealed significant effects of variety, type of fertilizer and variety Ã fertilizer type on active C uptake by actinomycetes. Rice variety significantly influenced the active fungal and Gram-negative bacterial groups, while none of the factors affected Gram-positive bacteria. Active Gram-negative bacteria were higher with BG variety, whereas fungi and actinomycetes were higher with KH variety in both inorganic and organic fertilizer applied fields. Gram-negative and Gram-positive bacteria were the most active functional groups in the paddy soil microbial community, whereas actinomycetes only relied to a minor extent on rhizodeposit C to meet their energy requirement. It is concluded that rice microbial communities differ significantly as a function of cultivation practices, potentially showing a large impact on ecosystem processes such as greenhouse gas emissions and plant nutrient availability.
