Environmental parameters affecting the concentration of iodine in New Zealand pasture
(American Society of Agronomy, Crop Science Society of America & Soil Science of America, 2019-08-21)
Iodine (I) is an essential trace element commonly deficient in agricultural systems. Whereas there is much information on I in food crops, there is a lacuna of knowledge on the environmental factors that affect pasture I ...
The influence of rock fragments on field capacity water content in stony soils from hard sandstone alluvium
(Elsevier, 2021-05-01)
Worldwide, rock fragments (RFs) are generally considered inert with respect to bulk soil hydraulic properties, such that all soil water retention properties predicted by national pedotransfer functions (such as S-map) are ...
Abiotic processes dominate CO₂ fluxes in Antarctic soils
(Elsevier, 2012-10)
Ecosystems within the McMurdo Dry Valleys of Antarctica are highly sensitive to environmental change. Increases in soil temperature and/or moisture content may dramatically change rates of soil respiration and soil carbon ...
Pathways of soil genesis in the Coast Range of Oregon, USA
(Springer Netherlands on behalf of the Royal Netherlands Society of Agricultural Science, 2013-06)
Background and Aims: Soil chronosequences on marine terraces along the Pacific Coast of California and Oregon show evidence of podzolization, though soils ultimately evolve to Ultisols. It is not clear if this pathway of ...
Evidence of prehistoric wind erosion of the Mackenzie Basin, South Island, New Zealand: an assessment based on ¹³⁷Cs and Kawakawa-Oruanui tephra
(CSIRO Publishing, 2015-01-12)
Many authors have reported significant soil erosion resulting from the grazing of sheep, rabbit plagues and invasion of the exotic Hawkweed (Hieracium sp.) in the sub humid alpine region of Mackenzie Basin, South Island, ...
Soil profile inversion in earthquake-induced liquefaction-affected soils and the potential effects on urban trees
(Elsevier B.V., 2014-01)
A sequence of three large earthquakes in 2012/2011 caused liquefaction ground damage to over a third of Christchurch, New Zealand. This paper presents results of a characterisation of liquefaction-affected soil (LAS) and, ...
Quantifying ecosystem rejuvenation: foliar nutrient concentrations and vegetation communities across a dust gradient and a chronosequence
(Springer Netherlands on behalf of the Royal Netherlands Society of Agricultural Science, 2013-06)
Background and aims: Due to long-term weathering of land surfaces, aeolian nutrient contributions can become essential to maintain ecosystem fertility and avoid retrogression. However, studies that consider the qualitative ...
Upbuilding pedogenesis under active loess deposition in a super-humid, temperate climate — quantification of deposition rates, soil chemistry and pedogenic thresholds
(Elsevier, 2012-11)
Although the importance of dust deposition as an integral component of terrestrial biogeochemical cycles is well-recognised, few studies have directly addressed pedogenic processes associated with dust deposition on the ...
