A formula for predicting advection-dispersion in the vadose zone at uneven drainage intervals
(American Geophysical Union, 2000-10)
A computational method is presented for predicting one-dimensional advective-dispersive solute transport with linear equilibrium sorption, for complex solute input histories associated with uneven intervals of transporting ...
Rapid assessment of xenobiotic toxicity : a dissertation submitted in partial fulfilment for a Bachelor of Science with Honours at Lincoln University
(Lincoln University, 2001)
Conventional analytical techniques for monitoring toxicity offer high precision but are disadvantaged by the high cost of specialised equipment, the need for trained personnel and the observation that measured levels do ...
Dynamics of nitrous oxide in groundwater at the aquatic-terrestrial interface
(Blackwell Publishing, 2007-04-10)
Few data are available to validate the Intergovernmental Panel on Climate Change's emission factors for indirect emissions of nitrous oxide (N₂O). In particular the N₂O emissions resulting from nitrogen leaching and the ...
Accounting for the utilization of a N₂O mitigation tool in the IPCC inventory methodology for agricultural soils
(Springer Netherlands, 2007)
In this study we review recent studies where dicyandiamide was used as a nitrification inhibitor to reduce both N₂O emissions from urine patches and nitrate leaching from pasture systems, and which led to the development ...
Estimating values of environmental impacts of dairy farming in New Zealand
(Taylor & Francis on behalf of The Royal Society of New Zealand, 2009)
New Zealand is the world’s largest exporter of dairy products, supplying about one third of global trade. The dairy sector strives to maintain international competitiveness by continued increases in productivity and ...
