Abstract

Flooded rice paddy soils represent a typical anaerobic freshwater habitat of microorganisms. The abundance and community structure of sulfate reducing prokaryotes (SRP) were investigated in order to understand their response to different fertilization practices in rice paddy, including control without fertilizers (CT) and arrangements of different chemical fertilizers of nitrogen (N), phosphorus (P) and potassium (K): N, NP, NK and NPK. The abundance of total bacteria and sulfate reducing prokaryotes of the rice paddy in summer and in winter were quantified by real-time PCR assays based on the 16S rRNA gene and the dissimilatory (bi)sulfite reductase gene (dsrAB) β-subunit. No significant di..
