National Soils Database [PDF]

open access: yes, 2007
End of project reportThe objectives of the National Soils Database project were fourfold. The first was to generate a national database of soil geochemistry to complete the work that commenced with a survey of the South East of Ireland carried out in ...

Effect of Vapor Pressure Deficit on Nutrient Uptake and Growth of Four Tomato Varieties Grown Hydroponically at Low Nutrient Concentrations

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Marginal water sources, such as wastewater, have been proposed as the basis for hydroponic nutrient solutions to improve the resource efficiency of greenhouse‐based tomato production. Such water sources are often low in plant‐available nutrient concentrations, and uptake and use efficiency of these nutrients may vary widely among ...

Do Short‐Term Legume–Maize Sequences Outperform Maize Monoculture Regarding Biomass Production and P Use Efficiency Under P‐Restricted Conditions?

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
In a short‐term pot experiment, three legume‐based crop rotations are being tested for their effects on the P cycle and P use efficiency compared to maize monoculture. Legume‐based crop rotations stimulate the P cycle by increasing acid phosphatase activity and carboxylate exudation.

Pared-down landscapes in Antarctica [PDF]

open access: yes, 1971
The frigid-arid climate that now prevails in ice-free parts of Victoria Land, Antarctica, inhibits glacial erosion. If certain landscapes, more or less remote from the great troughs of outlet glaciers, have been glaciated in the past, as seems very ...

Holocene sea‐level and environmental changes on the Isle of Mull, Scotland

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Sea‐level and coastal changes are reconstructed on the Isle of Mull, western Scotland, from 10 988 to 10 507 cal BP to the present. This research has produced the first SLIP for the Isle of Mull. A multiproxy approach including pollen, spore, foraminifera and diatom analyses reveals palaeoenvironmental changes from two coastal sites.

Cordilleran Ice Sheet early deglaciation inferred from evolution of Late‐Pleistocene glacial Lake Dzulh Stun in east‐central British Columbia, Canada

open access: yesJournal of Quaternary Science, EarlyView.
Abstract We document the early decay of the Late‐Pleistocene Cordilleran Ice Sheet in the central portion of the Rocky and Cariboo Mountains and the Rocky Mountain Trench in east‐central British Columbia. Glacial lakes impounded at the eastern margin of the ice sheet occupied watersheds on the west flank of the central Rocky Mountains, leaving ...

Holocene palaeoenvironmental reconstruction of sea level, coastal and vegetation changes along the southern Solway Firth, United Kingdom

open access: yesJournal of Quaternary Science, EarlyView.
Abstract Holocene relative sea level (RSL) changes were reconstructed from four sites along the less‐studied southern Solway Firth. A multiproxy approach, including lithostratigraphical and biostratigraphical analyses, combined with radiocarbon dating, produced ten sea level index points (SLIPs).

From Ice to Isolation: A geochemical reconstruction of the palaeoenvironmental evolution of Gairloch, NW Scotland (UK), since the Last Glacial Maximum

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Complex relative sea‐level (RSL) changes are associated with the deglaciation of the British and Irish Ice Sheet (BIIS). Sediment archives from Loch Bad na h‐Achlaise, an isolation basin in NW Scotland, UK, span Late Glacial to Holocene time and record sea‐level change and ice proximity via a geochemical and biostratigraphic multiproxy ...

Reconstructing post‐crisis recovery in the hinterlands of Constantinople: A high‐resolution first‐millennium CE pollen record from Lake Yeniçağa (NW Türkiye)

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Facing a novel plague pandemic, military invasions, and political–economic transformations, societies of the eastern Roman (Byzantine) empire had to adapt to a variety of pressures and new ways of exploiting their natural environments during the mid‐1st millennium CE.
