• Role of wind and other meteorological factors in evaporation and potential evapotranspiration : a dissertation submitted in partial fulfilment for the requirements of Post Graduate Diploma in Agricultural Science in the University of Canterbury [Lincoln College], New Zealand 

  Piyawongsomboon, Waree (Lincoln College, University of Canterbury, 1979)

  The purpose of this study was to apply the Penman and the Thornthwaite formula for estimating potential evapotranspiration and checked with the estimates based on pan evaporation data to present the role of north-westerly ...

• Control of gorse (Ulex europaeus) in dryland pasture converted from Pinus radiata forest 

  Edwards, Grant; Tozer, Katherine N.; Maxwell, Thomas M. R.; Marshall, Alan J. (New Zealand Plant Protection Society, 2007-09-24)

  The effect of crop sequence, pasture species mixture and nitrogen fertiliser on gorse establishment was monitored over 23 months in land converted from pine forest to a dryland sheep pasture. There were fewer gorse plants in ...
