Phosphorus transport in subsurface flow from a stony soil under irrigated and non-irrigated lucerne
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2020-07-29)
The extent of phosphorus (P) loss from soils under deep rooting crops such as lucerne is currently unknown. This study used large lysimeters (2.0 by 1.5 m) to quantify the amounts and forms of P in drainage under lucerne ...
Quantifying contaminant losses to water from pastoral landuses in New Zealand II. The effects of some farm mitigation actions over the past two decades
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2021-01-28)
In New Zealand the primary sector together with central and local government agencies have been promoting measures to mitigate the adverse effect of farming practices on water quality over the last few decades. We assessed ...
Surface runoff and losses of phosphorus from hydrophobic pastoral soils
The impact of soil water repellency (SWR) on soil phosphorus (P) mobility in surface water runoff remains contentious. Although SWR may cause a significant increase in surface runoff, especially in post-summer rainfall ...
Quantifying contaminant losses to water from pastoral landuses in New Zealand I. Development of a spatial framework for assessing losses at a farm scale
(Taylor & Francis on behalf of The Royal Society Te Apārangi, 2021-06-07)
Assessing the effectiveness of mitigation measures for reducing contaminant losses to water from pastoral farming systems is a challenging task. Two important factors that contribute to this challenge are (i) the considerable ...
