Application of organic amendments to soil is commonplace in domestic gardening. However, a vast array materials could be labelled as ‘compost’ by retailers and suppliers. We investigated six different currently used, or available for use, horticulture: composted bark, bracken, spent mushroom compost, horse manure, garden waste compost (at two application rates), peat. Using controlled field exp...
BACKGROUND Various studies have shown that the population densities of a number of forest vertebrates, such as orangutans, are higher on Sumatra than Borneo, and that several species exhibit smaller body sizes on Borneo than Sumatra and mainland Southeast Asia. It has been suggested that differences in forest fruit productivity between the islands can explain these patterns. Here we present a l...
The use of mineral soil analysis procedures in peat soils is considered unsuitable. Peat vulnerable to disturbance, which leads the damage inert structure, such as sifting and drying process. objective this study was obtain proper methods preparation extraction be used that can reflect conditions on field. experiment carried out laboratory Soil Science Department UGM by using samples taken from...
Arctic permafrost soils store large amounts of soil organic carbon (SOC) that could be released into the atmosphere as methane (CH4) in a future warmer climate. How warming affects the complex microbial network decomposing SOC is not understood. We studied CH4 production of Arctic peat soil microbiota in anoxic microcosms over a temperature gradient from 1 to 30 °C, combining metatranscriptomic...
Plant communities of the geologic past can be reconstructed with high fidelity only if they were preserved in place in an instant in time. Here we report such a flora from an early Permian (ca. 298 Ma) ash-fall tuff in Inner Mongolia, a time interval and area where such information is filling a large gap of knowledge. About 1,000 m(2) of forest growing on peat could be reconstructed based on th...
Northern peatlands occupy over 3 million km2 globally and contain the largest carbon (C) pool (typically >100 kg C m-2) among terrestrial ecosystems. Agri culture, forestry, and peat harvesting are the principal humaninduced activities that alter the peatland and hence the distribution and flux of carbon. As a prerequisite to those uses, the peatland is usually drained, which has longterm ef...
The objective of this work was to investigate the potential of three different kinds of Iranian peat and swamp soils as sources of organic matter (OM) in the Golestan Province, Northern Iran. Comparison of the peats was done in terms of the degree of humification on the von Post scale. Moreover, the X-ray fluorescence, X-Ray Diffractometry, and Fourier transform infra-red (FT-IR) techniques wer...
This paper presents the distribution of the terrestrial isopod Hyloniscus adonis (Verhoeff, 1927) in croatia. It was recorded for the first time at the edge of Dubravica peat bog and the adjacent forest. Additionally, it was collected at the edges of Đon močvar peat bog. Revision of the terrestrial isopod collection of the Croatian Biospeleological Society revealed that this species also occurs...
