Effect of long-term fertilization on bacterial composition in rice paddy soil

Changes in Bacterial Community Structure of Agricultural Land Due to Long-Term Organic and Chemical Amendments

“…Earlier pyrosequencing technique has revealed that microbial diversity is under the influence of the nature of ecosystem; soil from agricultural land and forest has different bacterial diversity whereas soil contaminated with heavy metal has reduced bacterial diversity [10]. Recently, Wu et al [50] demonstrated that abundance and composition of bacterial communities were not sensitive to inorganic fertilization while significantly affected by applying inorganic fertilizers with rice straw by using T-RFLP and 16S rRNA clone library. Similar to these results in the present study, direct negative effect of chemical fertilizer on bacterial diversity was observed and differences in observations are may be likely due to the different methodological approach and relatively deep mining of bacterial communities using 454 pyrosequencing.…”

Effects of fertilization regimes on tea yields, soil fertility, and soil microbial diversity

“…Many studies have focused on fertilization regimes on soil fertility Liu et al, 2010), crop yields (Venkatesan et al, 2004;Zhu et al, 2007) and microbial communities (He et al, 2008;Shen et al, 2010), but, up to now, the results of these reports are still not unanimous, and even conflicted. Moreover, most studies were concerned about the soils for growing food crops, like rice (Wu et al, 2011), wheat (Shen et al, 2010), maize or their combination for rotation (Kumar and Yadav, 2001;Yang et al, 2007;Hu et al, 2011), while few about the soils for planting tea (Venkatesan et al, 2004). Hence, it is necessary to examine the effects of fertilization regimes on tea yields, soil fertility, and microbial communities.…”

Changes in the abundance and structure of bacterial communities under long-term fertilization treatments in a peanut monocropping system

“…It is reported that crop rotation and organic matter inputs can increase the soil microbial biomass enhancing soil enzymatic activities involved in nutrient transformation which leads to improved soil quality and enhanced soil function (Acosta-Martínez et al 2010). Reports also indicate that chemical fertilizers which introduce N (nitrogen), P (phosphorus), and K (potassium) can also lead to the increased soil productivity and improve soil microbial properties such as microbial biomass C and N, and microbial diversity (McAndrew and Malhi 1992;Wu et al 2011). Improvements to crop yield and soil carbon over the short-term has been reported in some studies investigating the influence of chemical and organic fertilizers applications on soil bacterial diversity and community function (Crecchio et al 2001;Peacock et al 2001).…”
