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 ...
The effect of irrigation and urine application on phosphorus losses to subsurface flow from a stony soil
Diffuse losses of phosphorus (P) from agricultural land via subsurface flow (viz leaching) can result in degradation of surface water quality. Factors such as irrigation and soil pH can increase the solubility of P and its ...
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 ...
