Processes governing phosphorus availability in temperate soils
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2000)
Phosphorus losses from agricultural soil to water bodies are mainly related to the excessive accumulation of available P in soil as a result of long-term inputs of fertilizer P. Since P is a nonrenewable resource, there ...
Changes in Cd bioavailability in metal spiked soils amended with biosolids: results from a wheat seedling bioassay
(International Union of Soil Sciences., 2010-08)
Three contrasting soils were collected from the Canterbury region in New Zealand and treated with a one-off application of Cd (1, 5 and 10 mg/kg applied as sulphate), in the presence and absence of biosolids applied at a ...
Thermography to assess evaporative fluxes on organic amended water repellent soils
Soil water repellency (SWR) is natural phenomenon occurring in soils throughout the world. It is a surface property associated with the organic composition in soils that reduces the affinity of soil for water. Its impact ...
Can phosphorus fertilizers sparingly soluble in water decrease phosphorus leaching loss from an acid peat soil?
(John Wiley & Sons, Inc. on behalf of the British Society of Soil Science, 2016-09)
© 2016 British Society of Soil Science The potential risk of phosphorus (P) loss in surface run-off can be decreased using sparingly soluble forms of P fertilizer (e.g. reactive phosphate rock (RPR)). However, it is unclear ...
Effects of plantation forest species on soil properties
A poster showing significant depletion of topsoil P over 10 years following establishment of plantation forest on grassland was mainly attributed to enhanced mineralisation of readily extractable organic P due to a combination ...
Forage responses to lime and nitrogen fertiliser on land converted from pine forest to dryland pasture in Canterbury
(New Zealand Grassland Association., 2007)
A field trial was established to quantify the impacts of lime (0, 2.5, 5 and 10 t/ha) and nitrogen (N) fertiliser (0, 50, 100, 200 and 400 kg N/ha/year) addition on the dry matter (DM) production of a crop sequence of ...
Long-term atmospheric carbon dioxide enrichment decreases soil phosphorus availability in a grazed temperate pasture
Elevated atmospheric carbon dioxide (eCO₂) associated with climate change increases plant production and soil nutrient transformations. However, changes in soil phosphorus (P) availability and dynamics are unclear. We used ...
Variable effect of Trichoderma bio-inoculants on ectomycorrhizal colonisation of Pinus radiata seedlings
(Lincoln University, 2006-07)
The effect of Trichoderma inoculation on ECM growth and colonisation was investigated in both a pot experiment and in a dual plate bioassay.
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.
The biotic contribution to the benthic stream sediment phosphorus buffer
Benthic stream sediments interact strongly with phosphorus (P) and can buffer dissolved reactive P (DRP) concentrations. The sediment P buffer can be measured with the sediment equilibrium phosphate concentration at net ...
