“…In a study in northern spain (gartzia-Bengoetxea et al, 2009), these characteristics were found to be higher in semi-natural (beech and oak) stands than in cultivated mature pine. This result may be attributed to differences in annual organic matter inputs (Kavvadias et al, 2001), litter quality (sariyildiz et al, 2005) and the enmeshing effect of roots and associated mycorrhizal hyphae, which may contribute to stabilization of topsoil aggregates.…”

Ekológia (Bratislava), vol. 33, no. 1, p. 67-80, 2014. This paper deals with the evaluation of the effect of afforestation of previously arable land to soil characteristics changes. one of the main aims was to evaluate the effects of each forest species on the soil structure quality after afforestation. soil samples were taken at two climatically distinct subregions within the czech republic. Based on the different site conditions, two study sites were chosen at each locality for a total of four research sites. detailed soil survey and basic forest stand inventories were conducted at all four sites. The first locality was established in the rychnov nad Kněžnou district in the Protected landscape area of the orlické mountains (soil type a haplic cambisol). The second locality was established in the Prague-East district (soil type a haplic cambisol and a haplic stagnosol). afforestation had a positive influence on the soil physical characteristics which are important for the maintenance of soil stability. Forest cover has a major influence on increasing the soil porosity, by decreasing the reduced bulk density and increasing capillary and gravitational pores, which is crucial. afforestation was also found to be positively related to increases in soil organic matter content in different forms, both stable and unstable, and tendency of considerable soil organic matter accumulation not only in the layer of surface humus but also in the entire soil profiles of the research sites. The main contributor to soil improvement after afforestation is the formation of stable soil aggregates. This is typical also for spruce and pine cover.

“…Moreover, the land change/conversion of natural wetland can change carbon release to the atmosphere [6][7]. Although organic materials, soil microflora, and enzyme activities are important components of the soil matrix and their transformation plays a significant role in soil fertility and biogeochemical cycles from the local to the global level, little is known about the changes in land use and their effects on soil properties in the karst wetland system [5].…”

To gain a better understanding of the impact from the land-use change in the Huixian karst wetland system, we analyzed soil microflora, enzyme activities, and physicochemical properties from three land-use types (natural wetland, paddy field, and dry farmland). The results showed that soil pH, soil organic carbon, total nitrogen, cation exchange capacity, exchangeable Ca and Mg, and the cellulase and alkaline phosphatase activities in the dry farmland were significantly lower than those in the paddy field and natural wetland (p<0.05). However, soil pH, soil organic carbon, total nitrogen, cation exchange capacity, exchangeable Ca and Mg, and the cellulase and alkaline phosphatase activities made no significant difference to the paddy field and the natural wetland (p>0.05). Moreover, the soil microbial biomass carbon and nitrogen in the dry farmland were also lower than those in the paddy field and natural wetland, although no significant differences were observed (p>0.05). This suggests that, in the alkali condition, natural wetland with high biomass and weak microbial activity may be an important carbon sink. In the CCA biplot, it can be seen that the natural wetland cluster intersects with the paddy field cluster and the dry farmland cluster in the same quadrant (although the paddy field and the dry farmland clusters are separate). Therefore, we concluded that the natural wetland usually was reclaimed as paddy field or dry farmland directly for agricultural output in the Huixian karst wetland system. The paddy field has a waterlogged condition and shows the similar results to natural wetland, which can be regarded as artificial wetland. In view of the similar ecosystem services by paddy fields as substitutes of natural wetland, if the degradation trend of natural karst wetland can't be reversed, the paddy field should be preserved in the Huixian karst wetland system for its ecosystem service.

“…However, the majority of measurements were based on various forms of total soil carbon (Guo and Gifford 2002) measured using either dry combustion (Van Moort and De Vries 1970) or organic carbon (wet oxidation; Walkley and Black 1934). These methods provide generally useful information; but provide little discrimination of SOM (Gartzia-Bengoetxea et al 2009). A more informative approach is to partition SOM having mean residence time varying from months to centuries into conceptual pools with different levels of stability (Christensen 2001;von Lutzow et al 2007).…”

Soil carbon and litter development along a reconstructed biodiverse forest chronosequence of South-Western Australia

Soil organic matter (SOM) increases with time as landscape is restored. Studying SOM development along restored forest chronosequences would be useful in clarifying some of the uncertainties in quantifying C turnover rates with respect to forest clearance and ensuing restoration. The development of soil organic matter in the mineral soils was studied at four depths in a 16-year-old restored jarrah forest chronosequence. The size-separated SOM fractionation along with d 13 C isotopic shift was utilised to resolve the soil C temporal and spatial changes with developing vegetation. The restored forest chronosequence revealed several important insights into how soil C is developing with age. Litter accumulation outpaced the native forest levels in 12 years after restoration. The surface soils, in general, showed increase in total C with age, but this trend was not clearly observed at lower depths. C accumulation was observed with increasing restoration age in all three SOM size-fractions in the surface 0-2 cm depth. These biodiverse forests show a trend towards accumulating C in recalcitrant stable forms, but only in the surface 0-2 cm mineral soil. A significant reverse trend was observed for the moderately labile SOM fraction for lower depths with increasing restoration age. Correlating the soil d 13 C with total C concentration revealed the re-establishment of the isotopically depleted labile to enriched refractory C continuum with soil depth for the older restored sites. This implied that from a pedogenic perspective, the restored soils are developing towards the original native soil carbon profile.
