“…However, it decreased in the oldest forest stand due to the decline in nitrification rate. This result is consistent with earlier studies reporting that nitrification rate or percent nitrification is greater in young stands than in old stands in both natural and plantation forests (Robertson and Vitousek 1981;Idol et al 2003;Tateno et al 2009), although the underlying mechanisms are still unclear. The decline in nitrification rates and percent nitrification seemed to be associated with the limited primary productivity in late succession (Ryan et al 1997).…”

Forest development in temperate regions is considered to be a global carbon sink. Many studies have examined forest development after harvesting or fire from aboveground (e.g., biomass) or belowground (e.g., soil nutrient) perspectives. However, few studies have explored forest development from both perspectives simultaneously in cool-temperate forests in Japan. In this study, we examined changes over 105 years in both aboveground and belowground components during secondary natural succession. The aboveground biomass increased for 50 years and reached a plateau in a 105-year-old stand. The N mineralization rate increased during succession for 50 years, but showed a decline in the 105-year-old stand due to the decrease in the nitrification rate in late succession. The percent nitrification (i.e., relative contribution of nitrification to N mineralization) decreased significantly with increasing forest stand age. The N mineralization rates had significant relationships with N concentrations of the dominant tree foliage and litter fall and with the amount of litter fall N. Meanwhile, other belowground properties (i.e., soil pH, phenol concentration, soil microbial respiration, and litter mass loss) did not show any significant relationship with forest stand age. This may be because the soil at the study sites was heterogeneous and consisted of Cambisols and Andosols, the latter of which originally has high organic matter content, and thus may have buffered the effect of the aboveground development. These results indicate that belowground N dynamics are more closely associated with aboveground development than other belowground properties in these forests.

“…Earlier studies have examined changes in belowground N dynamics during forest development (Vitousek et al 1989;Idol et al 2003;Trap et al 2009;Yan et al 2009). These studies have shown that the direction of changes in N availability during forest development can vary across study sites.…”

“…This suggests that with ageing forest tree species would strongly influence the litter quality and the microbial activities and consequently, the soil and whole ecosystem functions. Idol et al [19], also observed a low nitrification under older plots in a 100-year hardwood chronosequence. Disturbances of topsoil caused by clear-cutting and plantation could also modify the soil properties and the microbial activity.…”

Effect of tree species substitution on organic matter biodegradability and mineral nutrient availability in a temperate topsoil

-In the Breuil-Chenue experimental site (Morvan, France), the native forest, a 150-year-old coppice with standards dominated by beech was partly clear-cut thirty years ago and replanted with several tree species. Soil samples were collected from the A 1 horizon, in the 0-5 cm layer of the preserved native forest and three plantations: European beech, Douglas-fir and Norway spruce. Aliquots of 0-2 mm sieved soils were incubated for 40 days under laboratory conditions (15 • C, water-holding capacity). Carbon-mineralization was monitored; mineral nitrogen, water-extractable organic carbon and mineral elements were determined before and after the incubation. The release of CO 2 decreased in the order: spruce > native forest > beech > Douglas-fir, whereas nitrogen net mineralization decreased in the opposite order. Douglas-fir and beech soils were characterised by high nitrification activity and high solubilization of Ca, Mg, and Mn. Native forest and spruce soils were characterized by low nitrification activity, high carbon-mineralization and high solubilization of Fe and Al.forest tree species substitution / topsoil organic matter / biodegradability / nutrient availability / carbon and nitrogen mineralization Résumé -Effet de la substitution des essences forestières sur la biodégradabilité des matières organiques et la disponibilité des éléments majeurs dans les horizons superficiels d'un sol tempéré. Il y a 30 ans, dans le site atelier de Breuil-Chenue (Morvan, France), la forêt native, un taillis sous futaie de 150 ans à dominante de hêtre, était partiellement coupée à blanc, puis replantée avec diverses essences. Des échantillons de sol ont été prélevés dans l'horizon A1 (0-5 cm) sous la forêt native préservée et les plantations de hêtre, Douglas et épicéa.

“…Recovery processes in forest ecosystems can be elucidated by comparing stands with similar features except ''stand age'' (i.e., years after disturbance and subsequent secondary growth or replanting; Johnson and Miyanishi 2008). Several studies examining N cycling in a wide range of forest ecosystems have used the chronosequence approach to document changes during forest re-establishment after clear-cutting, wildfire, or land use change (Idol et al 2003;White et al 2004;Bond-Lamberty et al 2006;Yermakov and Rothstein 2006;Davidson et al 2007). However, these studies were unable to provide a sufficient explanation of how tree growth processes affect N cycling, because they compared forest stands that differed in tree species composition, soil properties, geology, or climatic conditions.…”

We examined soil N dynamics, including inorganic N concentration, net N transformation rates, and estimated plant N uptake (EPNU) from soil N budgets, and litterfall inputs, in five Japanese cedar plantation stands of different ages (5, 16, 31, 42, and 89 years) in the Mt Gomadan Experimental Forest (GEF). Net soil N mineralization and nitrification rates did not differ significantly between the youngest and oldest stands; soil moisture and inorganic N concentration were higher in the youngest stand. The EPNU was highest in the 16-year-old stand and lowest in the 31-year-old stand, and had a significant negative correlation with litter C:N ratio. The oldest (89-year-old) stand had a higher soil C:N ratio, lower proportion of nitrification rate to mineralization rate (%NIT), and higher estimated plant NH 4? uptake than did the other stands, indicating that changes of soil organic matter quality can alter soil N dynamics. These results suggest that as a Japanese cedar plantation develops, soil N dynamics can be altered by the quantity and quality of input litter and soil organic matter, and can generate the imbalance between N supply from soil and N demand by plant.
