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. ...
The efficacy of good practice to prevent long-term leaching losses of phosphorus from an irrigated dairy farm
(Elsevier, 2019-03-01)
Phosphorus (P) can be leached from intensive land uses, including grazed dairy farming. There is some evidence to suggest that P-leaching can enrich groundwater, especially where fertiliser or farm dairy effluent P (FDE) ...
Effects of lime and organic amendments derived from varied source materials on cadmium uptake by potato
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, Inc., 2017-07)
Repeated applications of Cd-rich phosphate fertilizers have resulted in elevated concentrations of this toxic element in some New Zealand soils. Exceedance of the food safety standard for Cd (0.1 mg kg⁻¹ fresh weight) has ...
The mitigation of phosphorus losses from a water-repellent soil used for grazed dairy farming
(Elsevier, 2020-03-15)
Phosphorus (P) losses via surface runoff can be large. Soil water repellency (SWR) occurs in warm and dry conditions. If SWR coincides with P fertiliser applications, the risk of P loss by surface runoff may increase. ...
Changes in soil phosphorus availability and potential phosphorus loss following cessation of phosphorus fertiliser inputs
(CSIRO Publishing, 2013-09-23)
Long-term application of phosphorus (P) fertilisers to agricultural soils can lead to in the accumulation of P in soil. Determining the rate of decline in soil P following the cessation of P fertiliser inputs is critical ...
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 ...
Can the application of rare earth elements improve yield and decrease the uptake of cadmium in ryegrass-dominated pastures?
(CSIRO Publishing, 2015)
© 2015 CSIRO. Rare earth elements (REEs) have been linked to increases and decreases in plant growth and the uptake of biotoxic metals such as Cadmium (Cd). We hypothesised that under the right soil and climatic conditions ...
Treatment of pasture topsoil with alum to decrease phosphorus losses in subsurface drainage
(Elsevier B.V, 2015-09-01)
Phosphorus loss from land can impair surface water quality. Losses via subsurface flow can be substantial, but most strategies to mitigate P losses focus on surface runoff. Aluminium sulphate (alum) was applied at 25 and ...
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 ...
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 ...
