“…Natural encroachment of forest plant communities to wood pasture in northern part of Klamputė significantly increased SOC content, especially in the deeper soil layers. One of the possible explanations for this is that the residues and roots of grasses decompose faster than residues and roots of broadleaf trees, likely due to the lower lignin found in grasses (Pinno, Wilson, 2011). In addition, the soil was more humid and more acidic in the area which was prevailed by forest plants (Šlepetienė et al, 2013), therefore the conditions were unfavourable for complete mineralization of organic residues.…”

The soils of Natura 2000 protected areas (Endocalcari-Endohypergleyic Cambisols, Fluvi-Eutric Fluvisol and Endohypogleyi-Eutric Fluvisols) and agrarian lands overgrown with grasses (Endocalcari-Endohypogleyic Cambisols) were investigated in this research in 2012. The soil organic carbon (SOC) concentrations decreased with the depth in all treatments, and the highest values were measured at 0-10 cm soil layer in pre-mainland section of middle reaches of the Nevėžis (76.8 g kg -1 ) and in old semi-natural pasture (49.5 g kg -1 ). The exclusive importance of the agrarian soil occupied with grasslands and long-lived swards and soils of protected areas occupied with natural meadows for environmental quality was revealed, because organic carbon was accumulated and sequestrated in the form of stable compounds. Natural encroachment of wood pasture by forest plant communities in the northern part of Klamputė wood pasture significantly increased SOC. The content of SOC was higher in all soil layers in wood pasture under restoration compared with surviving wood pasture. The carbon transformation processes in wood pastures differed depending on the depth: organic carbon was more stabilized in the 10-20 and 20-30 cm layers in the surviving wood pasture than that in wood pasture under restoration. It was established that the most intensive transformation and accumulation of organic carbon take place at 0-10 cm soil layer. The soils of protected areas and agricultural lands were characterized by differences in organic carbon stability. After applying the method of chemo-destructive fractionation the largest amount of residual organic carbon, which represents the resistance to degradation and the possibility to sequestration, was established in the soils under long-term use of grassland (pre-mainland section and old semi-natural pasture). The most unfavourable status of SOC, and thus all the soil organic matter (SOM), is observed in the riverside section. The labile carbon was dominant there, and the content of organic carbon resistant to chemo-destruction was very low in all soil layers.

“…Populusdominated forest, with relatively low root:shoot ratios, had significantly lower values for root length than grasslands (Pinno & Wilson 2013). This, along with moister soils (and potentially higher decomposition rates) in forest (Pinno & Wilson 2011), and higher activity of fungi and collembola beneath Populus (Steinaker & Wilson 2008b), results in significantly lower soil C in Populus-dominated forest than in grassland.…”

“…To maintain positive responses in Wyoming big sagebrush communities, subsequent shrub management efforts would need to occur about every 20-30 years . C in rangelands, including shrublands (Beier et al, 2009;Pinno & Wilson, 2011). Total soil C (organic plus inorganic C) in rangeland soils to a 1-m depth ranges from 90 to 266 Mg C ha -1 (Guo, Amundson, Gong, & Yu, 2006).…”

“…Total soil C (organic plus inorganic C) in rangeland soils to a 1-m depth ranges from 90 to 266 Mg C ha -1 (Guo, Amundson, Gong, & Yu, 2006). Total ecosystem C is greater for shrublands compared to grasslands, due to more aboveground biomass C (Pinno & Wilson, 2011;Qiu et al, 2012). The main factor controlling the fate of soil organic matter (which contains about 57% soil organic carbon, SOC, by weight), in rangelands is the effect of management on vegetation composition (Derner & Schuman, 2007).…”

This study investigated plant and soil (organic carbon, SOC) responses to shrub management in western U.S. rangeland dominated by Wyoming big sagebrush (Artemisia tridentata Nutt. ssp. wyomingensis Beetle & Young). Plants and soils were sampled in 2009 from paired sets of treatments (mowing to 10 cm height, aerial herbicide application of Spike® 20P [tebuthiuron]) in Sandy and Loamy ecological sites. Plant responses to mowing were consistent for both ecological sites with 1) no effects on live, but three-to four-fold increases in dead, Wyoming big sagebrush plant density, 2) reduced height and cover of Wyoming big sagebrush, 3) increased cover of perennial grasses, and 4) no effects on bare ground. For soils, increased SOC did occur with herbicide application in the Loamy site for both the 0-5 cm (43% increase) and 5-15 cm (17% increase) soil depths, which corresponded to annual soil C sequestration rates of 0.16 and 0.14 Mg C ha -1 yr -1 for the 0-5 and 5-15 cm soil depths, respectively. Shrub management in Wyoming big sagebrush-dominated rangelands affects the plant component for two different ecological sites, whereas effects on SOC were observed only when density of live Wyoming big sagebrush plants was reduced through selective herbicide use.
