Balancing water-quality threats from nutrients and production in Australian and New Zealand dairy farms under low profit margins
(CSIRO Publishing, 2017-06)
The loss of nitrogen (N) and phosphorus (P) from dairy-farmed land can impair water quality. Efforts to curtail these losses in Australia and New Zealand (Australasia) have involved a mixture of voluntary and regulatory ...
A review of the policies and implementation of practices to decrease water quality impairment by phosphorus in New Zealand, the UK, and the US
(Springer Netherlands, 2016-04)
© 2015, Springer Science+Business Media Dordrecht. The improper use of phosphorus (P) on agricultural land in developed countries is related to P losses that impair surface water quality. We outline policy in New Zealand, ...
Using organic phosphorus to sustain pasture productivity: A perspective
(Elsevier, 2014-06)
Organic phosphorus (P) in grazed pastures/grasslands could sustain production systems that historically relied on inorganic P fertiliser. Interactions between inorganic P, plants and soils have been studied extensively. ...
Direct exports of phosphorus from fertilizers applied to grazed pastures
(Crop Science Society of America with the American Society of Agronomy and the Soil Science Society of America, 2019-08-21)
Since its discovery in 1669, phosphorus (P) in the form of fertilizer has become an essential input for many agroecosystems. By introducing a concentrated P source, fertilizers increase short-term P export potential soon ...
Phosphorus speciation in a long-term manure-amended soil profile – Evidence from wet chemical extraction, ³¹ P-NMR and P K-edge XANES spectroscopy
(Elsevier, 2018-07-15)
Long-term application of manure can lead to an enrichment of phosphorus (P) in agricultural soils. To which extent this P leaches into drainage systems and thereby potentially contributing to eutrophication of surface ...
Ecological significance of mineral weathering in ectomycorrhizal and arbuscular mycorrhizal ecosystems from a field-based comparison
(Elsevier B.V., 2014-02)
Plants forming symbioses with ectomycorrhizal fungi dominate ecosystems worldwide, yet the advantage of ectomycorrhizal symbiosis compared with symbioses with arbuscular mycorrhizal fungi remains unknown. One hypothesis ...
Long-term phosphorus grassland experiment for beef production - impacts on soil phosphorus levels and liveweight gains
(Wiley-Blackwell, 2010)
Phosphorus is essential for plant and animal health. The aim was to determine the impacts of P fertilizer on changes in Morgan's soil test P (STP) and liveweight gain (LWG) of mature beef animals over the last 10 yrs ...
Nutrient-enriched soils and native N-fixing plants in New Zealand
(Wiley-VCH Verlag, 2019-02-06)
Approximately 40% of New Zealand's land mass is fertilized grassland with entirely non-native plants, but currently there is substantially increased interest in restoration of native plants into contemporary agricultural ...
Soil microbial biomass and the fate of phosphorus during long-term ecosystem development
(Springer Verlag on behalf of the Royal Netherlands Society of Agricultural Science, 2013-06)
Background: Soil phosphorus availability declines during long-term ecosystem development on stable land surfaces due to a gradual loss of phosphorus in runoff and transformation of primary mineral phosphate into secondary ...
A review of the cost-effectiveness and suitability of mitigation strategies to prevent Phosphorus loss from dairy farms in New Zealand and Australia
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, Inc., 2012-05)
The loss of phosphorus (P) from land to water is detrimental to
surface water quality in many parts of New Zealand and Australia.
Farming, especially pasture-based dairying, can be a source of P
loss, but preventing it ...
