Seventy years of data from the world’s longest grazed and irrigated pasture trials
(Springer Nature, 2021-02-10)
Pastures are the most widespread land use, globally. The Winchmore trials were established in 1948–1949 in Canterbury, New Zealand and examined either different rates of phosphorus (P) fertiliser on the same irrigation ...
Total soil cadmium concentrations in the Winchmore long-term phosphorus fertiliser trial are still increasing
(Taylor & Francis on behalf of the Royal Society of New Zealand, 2020-05-25)
Reliable data on the rate of cadmium (Cd) accumulation in soils that receive phosphorus (P) fertiliser is vital to help manage the impact of Cd in agricultural systems in New Zealand. Studies of the long-term P fertiliser ...
Transport of phosphorus in an alluvial gravel aquifer
(The Royal Society of New Zealand, 2015)
The transport of phosphorus (P) and bromide (Br) in an alluvial gravel aquifer was investigated in two tracing experiments: (1) injecting pulses of orthophosphate and (2) 10% diluted municipal effluent spiked with ...
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 ...
Cadmium losses from a New Zealand organic soil
(The Royal Society of New Zealand, 2016)
© 2016 The Royal Society of New Zealand. Cadmium (Cd) losses from acidic organic soils amended with phosphate fertiliser are potentially important for the assessment of Cd accumulation, but are currently poorly understood. ...
The impact of cattle grazing and treading on soil properties and the transport of phosphorus, sediment and E. coli in surface runoff from grazed pasture
(Taylor & Francis on behalf of The Royal Society of New Zealand, 2021-04-21)
Contaminant loss from grazed pasture can negatively affect freshwater quality. There is, however, little data on the impact of different levels of grazing/treading on contaminant loss measured under field conditions. This ...
