To date, occurrence and stimulation of different nitrification pathways in acidic soils remains unclear. Laboratory incubation experiments, using the acetylene inhibition and 15N tracing methods, were conducted to study the relative importance of heterotrophic and autotrophic nitrification in two acid soils (arable (AR) and coniferous forest) in subtropical(More)
An in situ 15N tracing study was conducted to investigate the characteristics of soil mineral nitrogen (N) production and conservation in acid forest soils of subtropical China. The six experimental soils were strongly acidic (pH ranged from 4.1 to 4.7), except for one soil, from an orange orchard which had a higher pH (5.7) due to lime application. Total(More)
