“…Additionally, the increasing contents of SOC and TN in soil also could stimulate AOB abundance (Orwin et al, 2010). In agreement with amoA gene copy numbers of archaeal (AOA) and bacterial (AOB) increased, the rates of O NH 4 in orchard soils were much higher than that in woodland soils, consistent with the findings of Zhang et al (2013a) in agricultural soils and Xue et al (2009) in tea plantation soils. Since the total gross rate of organic N mineralization was kept almost unchanged, the nitrification capacity increased with increasing orchard age (Fig.…”

“…This is probably due to a high N fertilizer application rate in tea soils. Previous studies showed that fertilized soils had higher nitrifying activity due to the increased release of ammonium from fertilizers and the accelerated growth of nitrifying populations (Martikainen 1985;Hayastu and Kosuge 1993;Aarnio and Martikainen 1996;Mendum et al 1999;Chu et al 2008;Xue et al 2009). The present study also shows that N fertilizer had a strong stimulating effect on soil nitrification.…”

“…High levels of nitrogen fertilizer are applied, altering N cycling and microbial community structure (45,54). Soils under tea plantations are often acidic, with pH values ranging from 3.5 to 5.5, but, despite the potential sensitivity of AOB to low pH, nitrification rates and nitrate concentrations are high (9,35,51,53). Soil type and vegetation have potentially additional effects on microbial community composition (27), and it is therefore pertinent to compare tea soils with other vegetated systems on the same soil type.…”
