Complexity of clay mineral formation during 120,000 years of soil development along the Franz Josef chronosequence, New Zealand
(Taylor & Francis Group on behalf of the Royal Society of New Zealand, 2017)
Weathering of primary silicates to secondary clay minerals over time affects multiple soil functions such as the accumulation of organic matter and nutrient cations. However, the extent of clay mineral (trans)formation as ...
Biotic interactions drive ecosystem responses to exotic plant invaders
(American Association for the Advancement of Science, 2020-05-29)
Ecosystem process rates typically increase after plant invasion, but the extent to which this is driven by (i) changes in productivity, (ii) exotic species' traits, or (iii) novel (non-coevolved) biotic interactions has ...
Soil organic phosphorus transformations along a coastal dune chronosequence under New Zealand temperate rain forest
The chemical composition of soil phosphorus can vary markedly during pedogenesis, which has implications for phosphorus availability to plant and microbial communities during long-term ecosystem development. We used NaOH–EDTA ...
Research and application of biochar in New Zealand
(ASA / CSSA / SSSA, 2016)
Readers will appreciate the comprehensive review of the latest biochar research and applications and gain critical guidance in best biochar generation and use.
Effect of long-term plant biomass management on phosphatase-producing bacterial populations in soils under temperate grassland
(Elsevier B.V., 2020-07)
Organic forms of phosphorus (P) account for over half of the total P present in most soils and make a significant contribution to P cycling and plant nutrition through the actions of various plant and microbial phosphatase ...
Validating novel oligonucleotide primers targeting three classes of bacterial non-specific acid phosphatase genes in grassland soils
(Springer International Publishing, 2018-06)
Background and aims: Microbially driven mineralization of organic phosphorus forms is of particular importance in the soil environment, where it becomes available to plants as inorganic orthophosphates. In acidic soils, ...
Upbuilding pedogenesis under active loess deposition in a super-humid, temperate climate — quantification of deposition rates, soil chemistry and pedogenic thresholds
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 ...
Potential phosphorus losses from organic and podzol soils: prediction and the influence of soil physico-chemical properties and management
(The Royal Society of New Zealand, 2015)
© 2015 © 2015 The Royal Society of New Zealand. Organic and podzol soils may have properties that exacerbate phosphorus (P) loss to surface water following development for pastoral agriculture, including high porosity and ...
Predicting the changes in environmentally and agronomically significant phosphorus forms following the cessation of phosphorus fertilizer applications to grassland
(Wiley on behalf of the British Society of Soil Science, 2012-06)
Phosphorus (P) loss from soil can impair surface water quality. Losses from soil are related to soil P concentrations, but agronomic measures such as Olsen P do not in many cases predict the potential for P loss. One ...
The effect of soil moisture extremes on the pathways and forms of phosphorus lost in runoff from two contrasting soil types
(CSIRO Publishing, 2017)
Soil moisture and Olsen P concentrations play an important role in phosphorus (P) losses in runoff. Under moisture-rich anaerobic conditions, the reduction of Fe-oxides dissolves P from the soil into solution that may be ...
