“…The mursh horizon of murshic soils contained less CaCO 3 , as well as, fewer mineral lime-free parts and apparently a higher content of organic matter in comparison with gleysols (Table 1). Observed stratification of mursh horizon, the loss of organic matter and the increased impact of underlying deposits on the properties of mursh are typical features of degradation processes related to water table lowering (Uggla 1968, Marcinek and Spychalski 1998, Piaoecik and Gotkiewicz 2004, Meller 2006, Bieniek and Grabowski 2007, Verry et al 2011). Mursh soils under study, had neutral reaction, whereas limnic deposits -alkaline, which did not distinguish them from other post-bog soils developed from carbonate sediments (Uggla 1976, Sowiñski and Lemkowska 2008, £achacz et al 2009.…”

“…These differences were caused by a more advanced degree of mineralisation and the changes in the contribution of particular constituents of the solid phase (Marcinek and Spychalski 1998, Verry et al 2011, Huat et al 2011. The loss of organic matter in the mursh horizons had a significant impact on the increase of specific and bulk density (Table 1 and 2), which has been confirmed by other studies on drained peatlands (Olkowski 1971, Krzywonos 1993, Marcinek and Spychalski 1998, Meller 2006 properties of mursh developed on limnic limestones in NW Poland Wallor and Zeitz 2016).…”

“…Lowering of groundwater level caused by agricultural use of the area leads to the interruption of peat formation process and the transformation of peat into mursh. Increase in oxygen diffusion intensifies mineralisation of organic formations and is the cause of visible changes in morphology, structure as well as physical, chemical and biological transformations defined as the mursh-forming process (Okruszko 1992, Piaoecik and Gotkiewicz 2004, Kiryluk 2009, Gnatowski et al 2010, Huat et al 2011, Verry et al 2011. Physical properties are among the main indicators of the degree of degradation of organic formations.…”

Post-bog soils developed on carbonate sediments are closely related to a young-glacial landscape and postglacial lakes. Drainage of biogenic accumulation area leads to a series of transformations in accumulated formations, including the process of decession. The studies conducted in the years 2009-2012 were focused on post-bog soils near lakes: Strzeszowskie, Sitno and Drawskie in Western Pomerania. The examined soils belong to murshic soils and gleysols (The classification of Polish soils). Mursh horizons contained from 0.2 to 43.3% of carbonate and from 27.2 to 77.6% of non-carbonates fractions (Ncf), and varying amount of organic matter depending on the degree of mineralisation. Specific density of surface horizons was in the range from 1.76 to 2.33 Mg·m -3 , and bulk density from 0.28 to 0.68 Mg·m -3 . Higher porosity was found in mursh organic soils in comparison to gleysols. The studies showed that the content of carbonate fraction was related with specific density, bulk density, porosity and water capacity. Obtained results of physical and physico-chemical analysis indicate that dewatering depth of post-bog soils developed on limnic limestone are reflected in worsened water retention properties and reduced capillary ascent in the upper layers of carbonate formations of gleysols.

Post-bog soils developed from limnic calcareous sediments are closely related to a young-glacial landscape and postglacial lakes in Northern Poland. The studies conducted in 2010-2012 on post-bog soils near lake Dubie (Równina Drawska, NW Poland), partially used as an arable land. The goal of research was to characterise some chemical and physical properties of post-bog soils developed from carbonate deposits near lake Dubie. The soils of the analysed area developed from lacustrine chalk and calcareous gyttja belong to black earth and mucky soils. Organic matter content in surface horizons ranged from 5.0 to14.2%, content of CaCO 3 from 27.2 to 55.2%, the highest carbonate content was found in arable soil. The soils of the study area were characterised by a narrow C/N ratio, low level of total form of P and a high content of Ca. Specific density of surface horizons was in the range 2.49 to 2.58 Mg⋅m -3 , bulk density from 0.445 to 1.212 Mg⋅m -3 . High porosity was also found in the examined formations, from 0.826 in surface horizons and 0.700 m 3 ⋅m -3 in limnic deposits.

Erosion from peat extraction areas is known to cause siltation of water courses and poor water quality. However, the main soil parameters affecting peat erosion and suspended sediment (SS) yields from different catchments are not well understood. This paper used peat properties (degree of humification, peat type, ash content, porosity, moisture content, bulk density, and shear strength) and novel erosion threshold measurements from intact soil cores to explain peat erodibility and spatial variations in SS concentrations (SSCs) and SS loads (SSLs) at 20 Finnish peat extraction sites. The erosion threshold measurements suggested that critical shear stresses for particle entrainment decrease with increasing degree of humification (von Post scale) and are significantly lower in well-decomposed peat than in slightly or moderately decomposed peat. Two critical shear stresses were obtained from moderately decomposed peat samples, indicating a degree of surface armoring by coarse peat fibers. Monitored long-term average SSC was highest at study sites with well-decomposed peat, while very fine-grained mineral subsoil explained some of the highest long-term SSC in areas where drainage ditches penetrated below the upper peat layer. Average SSL (kg d 21 ) at the study sites was best explained (R 2 5 0.89) by average discharge and surface peat decomposition level. Overall, this study provides new knowledge on peat erosion and critical shear stresses that can be used in water conservation and sediment management practices for cutover peatlands and other similar land uses.
