Geological Journal, EarlyView.This work advances landslide susceptibility mapping by incorporating short‐term trigger data with landscape susceptibility mapping. We also examine the importance of downsampling, watershed delineation and geospatial correlations in evaluating outcomes.

Geological Journal, EarlyView.Chemical states of Se and Br atoms in the KPg boundary sediments from Stevns Klint were studied using XAFS spectroscopy. The high concentrations of Se4+ could become an index of the degree to which the global environment was soiled with dust and ash derived from impact ejecta or volcanic eruptions.

The German Soil Systematics and the Rationale Behind Its Revision
Journal of Plant Nutrition and Soil Science, EarlyView.ABSTRACT Background The German Soil Systematics is a pedogenetic classification based on the morphological expressions of pedogenic processes and has been developed over several stages since 1952. The system has successfully been in use for soil classification and soil survey for almost 70 years.

Food Security Versus Environmental Health: The Nitrogen Dilemma
Journal of Plant Nutrition and Soil Science, EarlyView.ABSTRACT Nitrogen is an essential element for plant growth and, consequently, crop production. However, the cycling of nitrogen in the environment can have negative effects. Here, we review the historical development of scientific and public awareness of these effects and the influence this has had on political action to control them.

Points to be considered in the establishment of long-term field trials
Agricultural and Food Science, 1964 On the basis of the experience gained in the long-term field tests at the Experimental Station of Leteensuo, some of the factors have been examined which have to be taken into consideration when tests of this kind are established. It is noted that in the

Perspectives of High‐Resolution Mass Spectrometry in Soil Science
Journal of Plant Nutrition and Soil Science, EarlyView.ABSTRACT Soil biogeochemical research requires specific, sensitive, and accurate methods to identify and quantify organic molecules in order to trace biochemical processes and assess element cycling in complex, heterogenous systems. High‐resolution mass spectrometry (HRMS) has evolved into a transformative tool for unraveling the complex chemical ...

The temperature of peat soil at Leteensuo
Agricultural and Food Science, 1962 The soil temperature at depths of 20, 50 and 100 cm has been higher in the summertime in the cultivated fen soil at Leteensuo than in cultivated Sphagnum peat soil, while the latter again had higher temperatures than Sphagnum bog in its natural state ...

Journal of Quaternary Science, EarlyView.ABSTRACT Subfossil insect communities from the Quartz Creek site provide a detailed record of both Late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada. Fifteen Pleistocene assemblages (marine isotope stages [MIS] 4 to 2) are dominated by steppe–tundra and dry‐tundra taxa, particularly the weevils ...

Restoration of lowland raised bogs damaged by peat extraction - with particular emphasis on Sphagnum regeneration. [PDF]
, 1994 1. Revegetation trends in abandoned peat workings indicate that peat cuttings are generally too dry for spontaneous re-establishment of raised bog vegetation. The latter was restricted to small flooded peat pits which had recolonised 'hydroserally' to
