“…The values of soil organic matter content belong to the main factors influencing bulk density (e.g., Duffková, Kvítek 2009;Ruehlmann, Körschens 2009;Tolimir et al 2020) and other physical soil properties (Huntington 2007); the decrease of soil organic matter content led to the higher values of bulk density (e.g., Sakin et al 2011). The values of bulk density also depend on the texture, mineral constituents and porosity (Baver et al 1972;Vopravil et al 2017b); correlations of bulk density with total porosity were reported by Hemmat et al (2010) etc.…”

In the Czech Republic, the afforestation of agricultural land has been supported by providing subsidies from the government and the European Union. Afforestation of less-productive agricultural land provides many benefits including carbon sequestration, soil erosion control, biodiversity, water retention, cooling, social benefits, decreasing noise and light pollution, increasing air quality, wind speed reduction, oxygen production, wood production and non-wood products. In some aspects, it is possible to produce wood of the same quality on former agricultural land compared to permanent forest land. In this study, we attempted to find out the course of temperatures and volumetric water content as well as some other physical soil properties (at depths of 20, 40 and 60 cm) 9 years after the afforestation of agricultural land (warm, mild dry region of the Czech Republic) with a mixture of broadleaved tree species (Quercus robur L., Quercus rubra L. and Acer platanoides L.) or monospecific Pinus sylvestris L. stand; the study was performed in the period from April to the beginning of November 2020. Concerning the studied physical soil properties, the value of bulk density was higher (and total porosity lower) at a depth of 20 cm in Pinus sylvestris L. compared with agricultural land or the mixture of broadleaves; the water stability of soil aggregates was higher after the afforestation with the mixture of broadleaves. The temperature was lower in the soil of afforested plots (at all studied depths) compared to the agriculturally used land. Differences in rainfall interception, transpiration, soil<br />(and forest floor) properties and other factors could influence the obtained values of water content in the soil of the studied plots. The average volumetric water contents were the highest in the plots with Scots pine (depth of 20 cm) and broadleaves (depth of 40 cm), and on the control plot (depth of 60 cm). The volumetric water content at a soil depth of 20 cm was not significantly (P > 0.05) different when the plot with Scots pine and agriculturally used land were compared. In all other cases and depths, the differences between plots were significant (P < 0.05).

“…Sites with a fast rate of recovery, namely post‐mining sites especially where grading and topsoil application is avoided (Cejpek et al, 2013; Frouz et al, 2018) as well as post‐fire succession, which were mostly forest sites, are characterized by high macroporosity (low compaction). On the other hand, arable land and meadows have lower porosity than forests and often suffer from larger soil compaction due to agricultural machinery movement (Gajić et al, 2008; Tolimir et al, 2020). Also, other post‐industrial sites are often compacted due to the moving of various types of earth moving machinery (Burger et al, 2020; Minea & Secu, 2014).…”

Potential of vegetation and woodland cover recovery during primary and secondary succession, a global quantitative review

Succession is a basic natural process of ecosystem recovery, it may start completely de novo (primary succession) or after serious disturbance of the previous ecosystem (secondary succession). Despite most reclamation and restoration approaches depending on it and despite extensive previous research, we found no worldwide review that would describe the pattern of vegetation cover and woody vegetation recovery in individual types of succession and explore major factors that affect the speed of vegetation recovery. To fill this gap we have searched world literature and extracted data about 244 succession series about total vegetation cover and 113 about woody vegetation cover. The rate of vegetation cover recovery is significantly slower during primary succession than during secondary succession, this however not apply to woody vegetation. The type of disturbance affects the speed of recovery, post‐mining sites recover fastest among primary succession and older fields were the fastest among secondary succession, the slowest one being succession in glacier retreats. Latitude, soil pH, the size of the disturbed area, temperature, and actual evapotranspiration affect the rate of vegetation recovery in primary succession, while only latitude affects secondary succession. Some other factors affect succession after a specific disturbance. The study shows that succession can be an effective tool to restore vegetation cover and woody vegetation on many occasions. We expect that differences in the nutrient availability determine differences in the rate of total vegetation cover recovery, while soil porosity (compaction) may be an important factor affecting woody vegetation recovery.

“…Thirty years after afforestation with Eucalyptus, SOM stocks recovered to nearly 70% of the SOM stocks determined in the natural forest [5]. The loss of SOM also affects other chemical and physical properties of soils, such as soil particle density and soil porosity [13], as well as aggregate stability and soil quality [14].…”

In the Ethiopian highlands, clearance of Afromontane dry forest and conversion to crop and grazing land lead to land degradation and loss of soil organic matter (SOM). Eucalyptus is often grown on degraded soils, and this results in the partial recovery of soil carbon stocks. The aim of this work was to assess the biological sources of SOM in this land-use sequence. In top-soils (0–10 cm) of four land-use systems, namely remnant natural forest, eucalyptus plantation, cropland, and grazing land, in the Ethiopian highlands, the origin of SOM was investigated. For this, a sequential extraction method was used, involving a solvent extraction, base hydrolysis, and a subsequent CuO oxidation. In these extracts, biomarkers (molecular proxies) were identified to characterize the SOM of the soil of the four land-uses. Putative lipid monomers of leaf, root, and microbial degradation products suggest that root inputs and microbial inputs dominate in SOM of all the land-uses, except grazing land. The ratios of syringyls, vanillyls, and cinnamyls showed that non-woody angiosperm plants were the predominant source for lignin in eucalyptus, cropland, and grazing land soil. In the soils of the natural forest, lignin originates from both woody angiosperms and woody gymnosperms. Our study shows the importance of root and microbial inputs in the formation of SOM, but also that, in the natural forest, legacies of previous forest cover are present.
