“…For pH measurement, suspensions were prepared using dry rubbed peat and 1 M potassium chloride at the ratio 1:5 (Kabala et al . ). Total organic carbon (TOC) and total nitrogen (TN) were determined using a VarioMax elemental analyser (no carbonates were present, thus the total carbon equalized the total organic carbon).…”

The aim of this study is to assess the impact of biotic and abiotic factors on peatland formation in the Central Sudetes (central Europe) during the late Holocene. The research methodology adopted allowed us to determine whether vegetation development and shallow peatland formation were affected by human activity. Knowledge of past changes might be useful in evaluating recent and future changes, and to avoid pitfalls in the present management of peatland ecosystems. A palaeoecological research study of four peatlands was conducted in the Stołowe Mountains (Central Sudetes, SW Poland). The results showed that these shallow peatlands originated in the middle to late Holocene (from 3301 BC to AD 1137). Palaeoecological records reflect continuous human impact on vegetation development and peat accumulation from the Middle Ages to the present (late Holocene). The strongest agrarian settler activity is observed in the High Middle Ages (AD 1200–1500). The human‐induced or wildfires observed in the late Holocene were an integral component of peatland ecosystems in the Central Sudetes. Moreover, palaeoecological analysis (sphagnum spores decline) and radiocarbon dating (AD 1870) confirmed drainage of the study area in the 19th century, which greatly affected the vegetation communities.

“…The soil bulk density, based on 5 cm 3 subsamples, was measured using a drying-weighing method (Chambers et al, 2011). For pH measurement, suspensions were prepared using dry peat and distilled water at the ratio 1:2.5 (Kabala et al, 2016). Total organic carbon (TOC) and total nitrogen (TN) for calculate TOC/TN ratio were determined using a VarioMax elemental analyzer.…”

Abstract. The aim of this paper was to assess the degradation stage of fen peatland located in the north-western part of the Opolskie voivodeship in accordance with "peatland degradation stages" classification. Understanding of the current state of peatland will be helpful in the future management and possible restoration. Field survey including vegetation and soil research were carried out in May 2013, soil material for laboratory analysis were collected by using "Instorf" peat sampler from four sampling points. Obtained results allowed to classify the study area (located within a larger peatland complex along the Prosna river valley) to minor stage of degradation, with spontaneous changes in vegetation community and soil cover. Only few species of plants typical for fen peatlands were recorded. Moreover, soil cover research did not confirm mursh forming process, typical for strongly degraded peatland areas. Obtained results may indicate that possible future restoration will bring the expected effect. It is very likely, that fen peatland vegetation will regenerate spontaneously, provided that diaspores of the key peat-forming plant species are available in the soil.

“…Soil observation was carried out on the variables of CH4 flux (Abduh and Annisa, 2016), pH H2O (Kabała et al, 2016), Eh (Toma et al, 2019), soluble-Fe (NH4OAc extract at pH 4.8) (Shahandeh et al, 1994) and organic materials (Jha et al, 2014) with observational intervals of 15 DAT. CH4 flux was measured by the closed chamber method.…”

Methane (CH4) emission from paddy rice fields is a global concern; however, engineering plant spacing can decrease CH4 emission. Due to this, field research was conducted to measure CH4 emissions from rice fields planted using jarwo 2:1 spacing, which has a 25 × 12.5 cm and 50 cm for the plant-free area (PFA), compared to tegel, which has a spacing of 25 × 25 cm. Each field was treated with organic fertilizer (mixture of cow manure and neem compost in a ratio of 1:1) with one of four doses: 0, 3, 6 and 9 tons/ha. The results showed that chemical properties such as soluble-Fe, soil organic matter (SOM), soil acidity (pH), and redox potential (Eh) were significantly correlated with CH4 emissions (0.52***, 0.47**, 0.36*, and-0.27* respectively). Jarwo 2:1 had lower CH4 emissions than tegel on all doses of fertilizer. The most efficient dose of fertilizer was 3 tons/ha applied jarwo 2:1 because it was able to produce rice up to 12 tons/ha with CH4 emissions of only 34 kg/ha/season, while CH4 emissions in tegel was 39 kg/ha/season. It is concluded that jarwo 2:1 with 3 tons/ha organic fertilizers can be recommended to farmers because it produces lower CH4 emissions and higher rice yield.
