Soils and their microbiological properties from a transect from Cape Horn to the Antarctic Peninsula [PDF]
Soils of the southernmost islands of South America (Cape Horn), the Falkland Islands, South Georgia, South Orkneys, South Shetlands, the Antarctic Peninsula and Poulet Island are described and analyzed for soil properties, soil taxonomy and ...

ABSTRACT Maintaining or even enhancing the productivity of arable soils is essential for ensuring food security, in addition to meeting feed and fibre needs. Relationships between yield, soil properties and management are complex and vary between environments; therefore, site‐specific knowledge of yield‐governing factors is needed to close any ...

Abstract Agricultural soils can contain a significant proportion of rock fragments, but most routine procedures for the estimation of soil carbon (C) and nitrogen (N) stocks promote the exclusion of the >2 mm component. This fractioning eliminates ironstone gravel, which is a common but poorly understood rock fragment found in Plinthic soils. Thus, the

Publisher Summary This chapter discusses podozol and podzolic soils. The term podzol is applied to the bleached horizon that occurs near the surface of soils in the taiga zone. The word was by no means restricted to soils that were well drained. The appreciation of “illuviation” as an important feature of soils with bleached surface horizons led to ...

Responses of ectomycorrhizal fungi to mineral substrates [PDF]
Boreal forest soils are complex, heterogeneous growth substrates where organic and mineral components provide nutrient resources for soil organisms and plants. Mineral nutrients are cycled between living and dead organic components of the forest soil and

Tundra plant communities along the mesotopographic gradient in NE Finland
In this study, we describe plant communities along the mesotopographic gradient in the low‐elevation subcontinental mountains of NE Finland (Utsjoki region). We sampled vascular plants, bryophytes and lichens along 18 mesotopographic ridge‐snowbed transects comprising a total of 180 plots.

ABSTRACT Kalkriese, near Osnabrueck (NW Germany), is considered the location of the ‘Battle of Varus’, where a coalition of Germanic tribes, under the leadership of Arminius, defeated three Legions under the command of Varus in 9 ad. Roman coinage and remains of military equipment prove that the Oberesch site at Kalkriese saw military operations ...

Cemented Horizons and Hardpans in the Coastal Tablelands of Northeastern Brazil
Horizons with varying degrees of cementation are a common feature of the soils from the coastal tablelands of Northeastern Brazil. In most cases, these horizons are represented by the following subsurface horizons: fragipan, duripan, ortstein, and placic.

Low vertical transfer rates of carbon inferred from radiocarbon analysis in an Amazon Podzol [PDF]
Hydromorphic Podzol soils in the Amazon Basin generally support low-stature forests with some of the lowest amounts of aboveground net primary production (NPP) in the region.

Hotspots of soil organic carbon storage revealed by laboratory hyperspectral imaging [PDF]
Subsoil organic carbon (OC) is generally lower in content and more heterogeneous than topsoil OC, rendering it difficult to detect significant differences in subsoil OC storage. We tested the application of laboratory hyperspectral imaging with a variety
