Assessment of the accuracy of profile available water and potential rooting depth estimates held within New Zealand's fundamental soil layers geo-database
(CSIRO Publishing, 2015)
© 2015 CSIRO. The Fundamental Soil Layers (FSL) serve historically as New Zealand's primary source of soil information. They contain a range of New Zealand's soil attribute information held in a spatial database. Despite ...
Challenges and opportunities in harnessing soil disease suppressiveness for sustainable pasture production
(Elsevier, 2016-04)
Grasslands are an important source of biodiversity, providing a range of essential ecosystem services such as ensuring water quality and soil carbon storage. An increasing proportion of grasslands are used for pastoral ...
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 ...
Flooding-induced N₂O emission bursts controlled by pH and nitrate in agricultural soils
(Elseiver, 2014-02)
Agricultural soils are a major source of the greenhouse gas nitrous oxide (N₂O) to the atmosphere. Increasing frequency and severity of flooding as predicted for large intensively cropped areas may promote temporary ...
The effect of urinary nitrogen loading rate and a nitrification inhibitor on nitrous oxide emissions from a temperate grassland soil
(Cambridge University Press, 2014-12)
Nitrous oxide (N₂O) emissions associated with urine nitrogen (N) deposition during grazing are a major component of greenhouse gas emissions from domestic livestock. The present study investigated the relationship between ...
Advances in understanding nitrogen flows and transformations: Gaps and research pathways
(Cambridge Journals, 2014)
The nitrogen (N) cycle is one of the best studied elemental cycles. However, the N flows and transformations, in particular in aggregated soils, at small scales and in plant-soil systems are not yet fully understood. ...
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 ...
Response of Populus tremula to heterogeneous B distributions in soil
(Springer Verlag on behalf of the Royal Netherlands Society of Agricultural Science, 2012-09)
Background:
Poplars accumulate inordinate amounts of B in their leaves and are candidate plants for the remediation of B contaminated soil. We aimed to determine the effect of heterogeneous B distribution in soil by comparing ...
A wood based low-temperature biochar captures NH₃⁻N generated from ruminant urine-N, retaining its bioavailability
(Springer Netherlands on behalf of the Royal Netherlands Society of Agricultural Science, 2012-04)
Aims: Ammonia (NH₃) can be volatilised from the soil surface following the surface application of nitrogenous fertilisers or ruminant urine deposition. The volatilisation of NH₃ is of agronomic and environmental concern, ...
Biochar adsorbed ammonia is bioavailable
(Springer Netherlands, under the auspices of the Royal Netherlands Society of Agricultural Science, 2012-01)
Biochar is produced as a by-product of the low temperature pyrolysis of biomass during bioenergy extraction and its incorporation into soil is of global interest as a potential carbon sequestration tool. Biochar influences ...
