Tillage-induced soil nitrous oxide fluxes from tow soils in the Manawatu : a thesis presented in partial fulfilment of the requirements for the degree of Master of Applied Science in Agricultural Engineering, Institute of Technology and Engineering, Massey University, Palmerston North, New Zealand [PDF]

, 2000
Enhanced greenhouse gas emissions of nitrous oxide (N₂O) induced by agricultural practices is believed to be the major anthropogenic source. Studies conducted in New Zealand generally from pasture suggest low N₂O emission, however, there is little ...

Plant responses to photoperiod [PDF]

, 2009
Photoperiod controls many developmental responses in animals, plants and even fungi. The response to photoperiod has evolved because daylength is a reliable indicator of the time of year, enabling developmental events to be scheduled to coincide with ...
