“…This is in accordance with previous studies, which showed that TOC stocks in soils generally increased after land-use abandonment (Knops and Tilman 2000;Hooker and Compton 2003;Poulton et al 2003;Kalinina et al 2009Kalinina et al , 2011.

“…Chronosequence approaches have been used frequently to investigate changes in vegetation and soil properties during secondary succession after land-use abandonment (Zak et al 1990;Hooker and Compton 2003;van der Waal et al 2006;Allison et al 2007;Kalinina et al 2009;Baer et al 2002;Kalinina et al 2011). The basic idea of this approach is to substitute space for time and to study a range of sites that constitute a timeline of successional states (Bardgett et al 2005;Walker et al 2010).…”

“…Generally, it has been observed that after cessation of cultivation the vegetation reverted to a plant community similar to comparable non-disturbed sites. In temperate ecosystems with forest being the natural vegetation, the succession proceeded from agricultural site, to grassland, then to shrubland, and ultimately to forest (Knops and Tilman 2000;Hooker and Compton 2003;Poulton et al 2003;Kalinina et al 2009Kalinina et al , 2011. Studies that considered long-term changes reported that it took almost 200 years in sandy soils of the taiga (Kalinina et al 2009), and 400-500 years in prairie soils (Matamala et al 2008) until the soils reached C stocks in the range of comparable non-disturbed sites.…”

Aims The objective of this study was to investigate changes in soil total organic C (TOC), total nitrogen (TN), phosphorus (P) fractions, and microbial community structure during secondary succession after abandonment of vineyards on calcareous soils. Methods Two chronosequences covering 200 years and differing in aspect and slope were established in Hungary, and the upper 10 cm of the mineral soils were studied. Results We found strong increases in TOC concentrations after land-use abandonment, especially at the south-exposed sites. The TOC/TN ratio increased by a factor of 1.3 in the south-west exposed chronosequence and by a factor of 1.6 in south exposed chronosequence. The concentration of labile P (NaHCO 3 -extractable P) diminished during the first 50 years after land-use abandonment, leading to low P availability at the later stages of the succession. The total organic P (TOP) concentration increased during the first 40 years after abandonment. At the later stages of succession, TOP concentrations decreased again, while the ratio of TOC/TOP increased continuously over 200 years. The ratio of arbuscular-mycorrhizal-fungi-to-bacteria (AMF/bacteria) increased strongly during the first decade after abandonment of the vineyards. Conclusions Our study indicates that impacts of former cultivation on secondary ecosystems persisted for more than a century, and that especially P concentrations showed long lasting legacy effects.

“…However, in the semiarid soils of the studied transect, particulate OC contributed < 10 % of bulk OC, while mineral-bound OC accounted for > 90 % (Table 3). This contrasts with observations from the steppe soils (mostly Chernozems) of European Russia (Breulmann et al, 2014;Kalinina et al, 2011), Canada (Plante et al, 2010), and China (Steffens et al, 2010) in which particulate OC represented > 20 % of bulk OC. Nevertheless, our results are in line with Bischoff et al (2016), who reported that a maximum of 10 % OC was present as particulate OC in the Chernozems and Kastanozems of the Kulunda steppe.…”

Organic matter dynamics along a salinity gradient in Siberian steppe soils

Abstract. Salt-affected soils will become more frequent in the next decades as arid and semiarid ecosystems are predicted to expand as a result of climate change. Nevertheless, little is known about organic matter (OM) dynamics in these soils, though OM is crucial for soil fertility and represents an important carbon sink. We aimed at investigating OM dynamics along a salinity and sodicity gradient in the soils of the southwestern Siberian Kulunda steppe (Kastanozem, non-sodic Solonchak, Sodic Solonchak) by assessing the organic carbon (OC) stocks, the quantity and quality of particulate and mineral-associated OM in terms of non-cellulosic neutral sugar contents and carbon isotopes (δ 13 C, 14 C activity), and the microbial community composition based on phospholipid fatty acid (PLFA) patterns. Aboveground biomass was measured as a proxy for plant growth and soil OC inputs. Our hypotheses were that (i) soil OC stocks decrease along the salinity gradient, (ii) the proportion and stability of particulate OM is larger in salt-affected Solonchaks compared to non-salt-affected Kastanozems, (iii) sodicity reduces the proportion and stability of mineral-associated OM, and (iv) the fungi : bacteria ratio is negatively correlated with salinity. Against our first hypothesis, OC stocks increased along the salinity gradient with the most pronounced differences between topsoils. In contrast to our second hypothesis, the proportion of particulate OM was unaffected by salinity, thereby accounting for only < 10 % in all three soil types, while mineral-associated OM contributed > 90 %. Isotopic data (δ 13 C, 14 C activity) and neutral sugars in the OM fractions indicated a comparable degree of OM transformation along the salinity gradient and that particulate OM was not more persistent under saline conditions. Our third hypothesis was also rejected, as Sodic Solonchaks contained more than twice as much mineral-bound OC than the Kastanozems, which we ascribe to the flocculation of OM and mineral components under higher ionic strength conditions. Contrary to the fourth hypothesis, the fungi : bacteria ratio in the topsoils remained fairly constant along the salinity gradient. A possible explanation for why our hypotheses were not affirmed is that soil moisture covaried with salinity along the transect, i.e., the Solonchaks were generally wetter than the Kastanozems. This might cause comparable water stress conditions for plants and microorganisms, either due to a low osmotic or a low matric potential and resulting in (i) similar plant growth and hence soil OC inputs along the transect, (ii) a comparable persistence of particulate OM, and (iii) unaffected fungi : bacteria ratios. We conclude that saltaffected soils contribute significantly to the OC storage in the semiarid soils of the Kulunda steppe, while most of the Published by Copernicus Publications on behalf of the European Geosciences Union. 14 N.

“…The greatest C fluxes caused by LUC are attributed to conversion of croplands to native vegetation and vice versa (Houghton and Goodale, 2004;Schlesinger, 1986). A large number of reviews and experimental studies report that abandoned agricultural land (remaining without cultivation) will be occupied by natural vegetation, that lead to organic C accumulation both in soil (Guo and Gifford, 2002;Kalinina et al, 2011Kalinina et al, , 2013Kalinina et al, , 2015Lopes de Gerenyu, 2008, 2009;Lyuri et al, 2010) and in vegetation (Kurganova et al, 2007Pérez-Cruzado et al, 2011;Post and Kwon, 2000).…”
