Alteration process during the post-agricultural restoration of Luvisols of the temperate broad-leaved forest in Russia

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

“…; Systat Software, Inc., San Jose California, US) to describe the post‐agricultural dynamics for C org , TN, and C mic content and BR in 0‐ to 5‐ and 5‐ to 10‐cm layers and to quantify the period (years) required for their full recovery (95% of the maximum value predicted by the sigmoidal model or parameter ‘a’; Table S6). We assume that 100 years is quite a reasonable age for reference soil in forest chronosequence to fit the sigmodal model because ~100 years is required for the full self‐restoration of Phaeozems in the deciduous forest zone (Kalinina et al, ; Lyuri et al, ).…”

“…The time of soil restoration during post‐agricultural evolution largely corresponds to the regeneration period for vegetation and is actually longer (Lyuri et al, ). Experimental observations and modeling (Romul Hum model) in soil chronosequence located in the deciduous forest zone showed no remarkable changes in C stocks after 100 years of restoration (Kalinina et al, ). Microbial parameters such as microbial biomass and basal respiration (0‐ to 10‐cm layer) were similar in Albeluvisols under 100‐ and 400–500‐year forests in south taiga (Susyan, Wirth, Ananyeva, & Stolnikova, ).…”

Effect of spring grass fires on vegetation patterns and soil quality in abandoned agricultural lands at local and landscape scales in Central European Russia

“…The world is experiencing a growing abandonment process of previously intensively managed agricultural lands (Baldock et al 1996;Silver et al 2000;Dunjó et al 2003;Benayas et al 2007;Bergen et al 2008;Zhang et al 2010aZhang et al , 2010bPrishchepov et al 2012;Alcantara et al 2013;Hansen et al 2013;Margono et al 2014). Many investigations have been devoted to the dynamics of soil and vegetation on abandoned lands, features of the spatial structure of their vegetation, changes in their biodiversity, in carbon and nitrogen budgets, and to peculiarities of carbon sequestration at different stages of forest recovery (Gough and Marrs 1990;Silver et al 2000;Baniya et al 2009;Tokavchuk 2010;Zhang et al 2010a;De Frenne et al 2011;Heikkinen et al 2014;Hou and Fu 2014;Kurganova et al 2014;Nyawira et al 2016;Arévalo et al 2017;Baeva et al 2017;Telesnina et al 2017;Kalinina et al 2018).…”

“…Spontaneous regrowth of forest vegetation occurs even in the fields that have been in agricultural use for a long period of time (up to several centuries and longer) (Utkin et al 2002(Utkin et al , 2005. However, as many researchers have noted, the density of the undergrowth in the regenerating forest vegetation on former arable lands varies greatly within the same climatic conditions and sometimes there are no trees at all (Utkin et al 2002;Prévosto et al 2011;Ruskule et al 2012;Novoselova et al 2016;Baeva et al 2017;Jagodziński et al 2017;Telesnina et al 2017;Kalinina et al 2018;Maslov et al 2018). Reasons of such striking differences in the undergrowth volume are not well investigated (Prévosto et al 2011;Ruskule et al 2012;Novoselova et al 2016).…”

“…In the Central Russian Upland, grass fires are common, but remain practically non-investigated. Researches on the overgrowing of abandoned lands do not take "the fire aspect" into account (Heikkinen et al 2014;Baeva et al 2017;Telesnina et al 2017;Kalinina et al 2018), while for other regions, fire risks were found to be positively linked to agricultural abandonment and agricultural landscape fragmentation (Martínez et al 2009;Zhang et al 2010a;Pausas and Fernández-Muñoz 2012;Pausas and Keeley 2014;Glagolev and Kogan 2016;Pavleychik 2016). Therefore, the objective of our study was to analyze the overgrowing on abandoned lands in the Central Russian Upland in connection with the grass fire history and to perform this study at the landscape and local scale.…”
