A field survey of soil pH and extractable aluminium in the Ashburton Lakes Catchment, New Zealand
(New Zealand Grassland Association, 2018-11-13)
Soil extractable aluminium (Al) concentrations have a strong impact on the establishment, growth and persistence of pasture legumes. A survey of 21 soil profiles in the Ashburton Lakes catchment was conducted to ...
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 ...
Geology, landforms and soils of the Waipara and Waikari regions of North Canterbury with an emphasis on lands used for viticulture
(Lincoln University and Landcare Research, 2015)
Soils play an important role in grape growing and wine making. Soils anchor the vine and act a reservoir of water and nutrients essential for growth. Soils influence the vine microclimate and therefore wine characteristi ...
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 ...
Phosphorus fertilization by active dust deposition in a super-humid, temperate environment – Soil phosphorus fractionation and accession processes
(John Wiley & Sons, Inc. on behalf of the American Geophysical Union (AGU), 2013-03)
The inventory of soil phosphorus (P) is subject to significant changes over time. The main primary form, bedrock-derived apatite P, becomes progressively lost through leaching, or transformed into more immobile and less ...
Rapid soil production and weathering in the Southern Alps, New Zealand
(American Association for the Advancement of Science, 2014-02-07)
Evaluating conflicting theories about the influence of mountains on carbon dioxide cycling and climate requires understanding weathering fluxes from tectonically uplifting landscapes. The lack of soil production and ...
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, ...
