“…Literature data about changes in soil carbon stocks due to land use changes are frequently discussed in review articles (Post & Kwon 2000;Guo & Gif-https://doi.org/10.17221/174/2018-SWR ford 2002; Laganiere et al 2010). The results of numerous studies have enabled the characterisation of changes in the composition of SOM as a result of ploughing forest soils (Gajic et al 2010;Ciric et al 2012). However, data referring to changes in the composition of SOM with the transition from arable land into forest are still scarce.…”

Soil aggregate structure and soil organic matter are closely interrelated and commonly considered as key indicators of soil quality. The aim of this study was to evaluate the effects of different fallow durations on indices of soil structure and humus status indicators. Studies were conducted on abandoned agricultural fields (15, 20 and, 35 years after abandonment). As a reference site, we used a cultivated field in the area. The experimental soil fields are classified as Gleyic Cambisols. Soil macroaggregates were separated with the sieve (dry sieve) to seven aggregate size fractions, i.e.> 10, 10–5, 5–2, 2–1, 1–0.5, 0.5–0.25 and < 0.25 mm. The humus status parameters of soils included the following indicators: soil organic carbon (Corg), humus reserves (QH), the degree of humification of organic matter (SOMdh), fractions of humic acids (HA) (free and bound with monovalent cations and Al2O3, Fe2O3, bound with Са2+ which forms humates, bound with clay minerals), fulvic acids (FA) (free aggressive) and ratio of HA to FA (CHA : CFA). After a fallow period of more than 20 years on the surface formation of a sod layer. A long-term fallow period had an impact on the mean weight diameter of the aggregates (MWD) and agronomically valuable aggregates (AVA). Fallow soils have a significantly better structure than soils under a cultivated field. Long-term cultivation leads to the deterioration of soil structure and the formation of large aggregates (>10 mm). The Corg content remains at the level of the background content when the soils are left fallow for less than 15 years and increases over time. The Corg in the upper 0–20 cm soil layer has been shown to increase from 3.55 to 8.74% on arable land that has been fallow for 35 years and has been largely associated with significant accumulation of organic matter within the plant root mass. Mature sites are characterized by an increase of fulvic acids in the humus composition in comparison with their arable analogues. The abandonment of soil agricultural use and the cessation of mechanical tillage results in the restoration of the natural structure of soils and the improvement of their agrophysical properties. Such studies have not been previously conducted in the Primorsky region of the Russian Far East.

“…In order to measure this susceptibility, we can make use of assessment of soil aggregate stability (Hillel 1980). Soil aggregate stability depends on soil type and sort, on the content of organic matter (Tisdall & Oades 1982;Haynes & Swift 1990;Šimanský et al 2013), on the biological activity of the soil (Oades 2005), fertilization (Annabi et al 2007), and also on the form of soil disturbance, frequency of passage of machinery (Safadoust et al 2006), vegetation cover (Gajici et al 2010;Peregrina et al 2010), and soil mass redistribution in the steep parts of slopes (Zádorová et al 2011). In the soil profile, there is also a varying dependence on the existence of various forms of CaCO 3 , on the presence of ferric oxide, clay, and pH KCl (Kodešová et al 2009).…”

Bartlová J., Badalíková B., Pospíšilová L., Pokorný E., Šarapatka B. (2015): Water stability of soil aggregates in different systems of tillage. Soil & Water Res., 10: 147-154.The influence of various agrotechnical measures on macrostructural changes in topsoil and subsoil was studied in the course of a four-year experiment. Macrostructure was evaluated according to the ability of soil aggregate to resist degradation. Three variants of soil tillage were established: ploughing to a depth of 0.22 m, reduced tillage (subsoiling to 0.35-0.40 m, and shallow disking of soil to a depth of 0.15 m). For observation, three locations were chosen in various production areas of the Czech Republic with differing soil and climatic conditions. In these locations crops were grown under the same crop rotation: rapeseed (Brassica napus L.), wheat (Triticum aestivum L.), maize (Zea mays), wheat (Triticum aestivum L.), and barley (Hordeum vulgare). After four years of different tillage, a change in the water stability of soil aggregates (WSA) was evident. It was found out that reduced tillage of soil positively influenced both the WSA and the yield of the crops grown. A relationship of positive dependence between WSA, the content of humus substances, and cation exchange capacity of soil was also found. According to the obtained results, for agricultural practice a classification scale of structural quality was proposed on the basis of statistics of one variable (average, its mean error and distribution normality).

“…Numerous researchers report similar results, attesting to structural deterioration of plow and subplow layers of Pseudogley and other soils, after conversion of forest and meadow into arable land (Dugonjić, 2001;Dugonjić and Đorđević, 2007;Dugonjić et al, 2008, Dugalić, 1998Dugalić et al, 2019;Vojinović, 1973;Cupać et al, 2006;Gajić, 1998;Gajić and Živković, 2006;Gajić et al, 2010;Marković, 2000;Kretinin and Lenov, 1978;Dilkova and Kerchev, 1986;Beare et al, 1994).…”

The impact of various types of uses of Pseudogley soils in southern Mačva and Pocerina on the iraggregate distribution and stability was studied on soil samples collected from profiles under forest, meadow and arable land, at three localities. The aggregate composition and stability were determined by Savinov'smethod. The soil structure was assessed by using Revut's coefficient of soil structure (Ks) and Vershinin's coefficient of soil aggregate structure (K A). The results show that the studied Pseudogley soils are characterized by an unfavorable structure, while the type of land use has a significant impact on the aggregate composition and stability, especially in surface Ah and Ahp horizons, where these differences are the most pronounced. The most favorable aggregate composition and highest wet-stability are found in Pseudogley profiles under forest vegetation. The aggregate distribution of meadow profiles was intermediate and of arable land the poorest. Statistical analysis of the collected data shows that Ks values, determined by dry sieving, were the highest in forest profiles (2.261.21 on average), while the values for meadow were 1.591.09 and of arable land 1.140.62. The values of K A , used to assess the aggregate stability to water, also show that forest Pseudogleys have the highest average values (2.051.03), followed by meadow (1.96 0.99) and cultivated soils (1.931.22). The results of correlation analysis indicate that Ks is negatively correlated with clay, pH value and base saturation, but positively correlated with soil humus (r=-0.77,-0.70,-0.81 and 0.79, respectively, p<0.01). Conversely, K A is negatively correlated with humus and positively correlated with clay, pH value and base saturation (r=-0.21, 0.82, 0.69 and 0.69, respectively, p<0.01).
