“…All SOM fractions in the uppermost layer (0–5 cm) increased after conversion of croplands to native vegetation in both chronosequences reflecting the increasing plant residues input to topsoil and their progressive transformation (Figure ). The same patterns in the shift of SOM quality were previously demonstrated during post‐agricultural successions in forest regions (Erokhova, Makarov, Morgun, & Ryzhova, ; Kalinina et al, ; Kalinina et al, ; Kalinina et al, ) and steppes (Jastrow, ; Kalinina, Barmin, et al, ; Lopes de Gerenyu et al, ). The post‐agricultural dynamics of SOM fractions (Figure ) mostly followed the total C org after cropland abandonment (Del Galdo et al, ; Erokhova et al, ; Gunina, Ryzhova, Dorodnikov, & Kuzyakov, ; Lima et al, ).…”

Recovery of organic matter and microbial biomass after abandonment of degraded agricultural soils: the influence of climate

et al. 2019

After abandonment of agricultural lands (ongoing on 220 million hectares worldwide), degraded arable soils undergo self‐restoration and development towards natural ecosystems. We studied the linkage between microbial properties and density fractions of soil organic matter (SOM) during post‐agricultural restoration of former arable Phaeozems and Chernozems. The chronosequence study was conducted in two contrasting bioclimatic zones of European Russia: deciduous forest (Luvic Phaeozem) and dry steppe (Calcic Chernozem). Each chronosequence included an arable soil, 3–4 soils with increasing periods after abandonment (from 7 to 35 years), and reference sites with native soils. The basal respiration (BR) and microbial biomass (Cmic) were closely correlated with the soil organic carbon (Corg) content as well as SOM density fractions: free particulate organic matter (fPOM), occluded particulate organic matter (oPOM), and mineral–SOM. The greatest increase in most properties was common in the top 0–5 cm and was maximal for fPOM and oPOM fractions (by 1.5–2.5‐times), Cmic (1.9‐times), and BR (1.5–2.5‐times). For the first time, the duration of full recovery of soil properties depending on climate were estimated. Generally, ~40–120 and 20–30 years in the forest and steppe, respectively, are required to restore Corg, total nitrogen (TN), and Cmic contents in the 0‐ to 5‐cm layer after the abandonment of agricultural lands. The maximal restoration rates of all properties are common in the first 15–20 years after abandonment.

“…It has been demonstrated that increasing aridity across a geographical gradient decreased SOC accumulation rate from 50 g C m −2 y −1 to 8–18 g C m −2 y −1 (Kalinina et al, ). In a chronosequential study considering pedogenesis, it was reported that SOC accumulation of Calcisols developed slowly while Solonetzes grew more rapidly towards natural soils (Kalinina et al, ). Different responses of carbon sequestration also appreciated within a time span of 30–40 years (Deng et al, ).…”

“…It is assumed that the surface soil is most affected by land use changes (Guo & Gifford, ; DeGryze et al, ) and after new plantations (Rodrigo Comino et al, , ). Therefore, a large number of studies are specifically concerned with SOC changes in the surface soils (Gabarron‐Galeore et al, ; Kalinina et al, ; Boecker et al, ; Zhang et al, ). We still lack reliable information about the SOC dynamic in subsoils and possible benefits of land abandonment on carbon sequestration of whole soil profiles.…”

“…Extensive studies have investigated changes in SOC stocks after land abandonment (Deng et al, 2013;Gabarron-Galeore et al, 2015a;Kalinina et al, 2015). There is a general agreement on a net SOC gain during succession following land abandonment (Guo & Gifford, 2002;Don et al, 2011;La Mantia et al, 2013).…”

“…There is a general agreement on a net SOC gain during succession following land abandonment (Guo & Gifford, 2002;Don et al, 2011;La Mantia et al, 2013). However, variability on SOC change derived from several factors such as climate, topography, soil type, soil depth and restoration age (Alberti et al, 2011;Bienes et al, 2016;Gabarron-Galeore et al, 2015b;Kalinina et al, 2015;Deng et al, 2016).

The Grain to Green Program in China which began in 1999 led to the conversion of 0.64 million ha of cropland to grassland on steep sloping landscapes. However, the pattern of natural vegetation succession following cropland has not been well represented in previous regional syntheses of land use change effects on soil organic carbon (SOC). A chronosequence study focusing on the vegetation succession and soil carbon stocks was conducted in the center of the Loess Plateau. The chronosequence included fields of 0, 2, 5, 8, 9, 10, 12, 15 and 25 years of self‐restoration after cropland abandonment, as well as a natural grassland reference. Plant coverage, species richness and plant biomass increased significantly with time of cropland abandonment. Over time, the species composition more nearly resembled a natural grasslands community. Cropland abandonment replenished SOC stocks by 3.6 kg C m−2 during the 25‐year self‐restoration, but the SOC accumulation was restricted to the upper soil profiles (0–60 cm). SOC accumulation rate was 88 g C m−2 y−1 in 0–30 cm and 55 g C m−2 y−1 in 30–60 cm soil depth, respectively. These carbon stocks were still significantly lower than those found in the natural grassland soil. Our results suggest that the recovery of plant communities and SOC stocks appears to be slow in this semiarid environment without revegetation effort along with appropriate field management, although the post‐agricultural soils have a high potential for carbon sequestration.

Carbon sequestration in Mediterranean soils following afforestation of abandoned crops: Biases due to changes in soil compaction and carbonate stocks

et al. 2021

Crop replacement by secondary forests increases soil organic carbon (OC) stocks.Quantifying this increase is subject to biases: the changes in soil compaction and, in calcareous zones, the changes in soil inorganic carbon (IC) content, which affect the carbon balance. How relevant are both biases, though? We studied this problem in NE Spain, subhumid Mediterranean, in a set of current crops, old forests, and new forests grown on croplands abandoned after 1956. We compared soil OC stocks on a fixed-depth basis (30 cm), and on an equivalent-mass basis: uppermost 425 kg m À2 of fine mineral matter (amount in crop soils). Down to 30 cm, OC stocks were lowest in crops (5.45 kg m À2 ) and highest in old forests (7.50 kg m À2 ), which gives a potential OC sequestration in the mineral soil of 2.05 kg m À2 . On an equivalent-mass basis, the potential is 2.50 kg m À2 , meaning that the fixed-depth criterion underestimates OC sequestration by more than 20%. These figures are surpassed by those of IC: crops store 17.73 kg IC m À2 down to 30 cm, old forests 12.28, suggesting a potential loss upon afforestation of 5.45 kg IC m À2 . Nevertheless, the lack of negative relationships between IC losses and OC gains within a given land use suggests that the contrasting IC stocks result from past management, mainly tillage. The decarbonation is only apparent. Our results stress the need of accounting for changes in carbonate content and soil compaction in future studies about carbon sequestration in soils.
