Environmental and agronomic constraints in dryland pasture and choice of species
Keyword(s):
Hawkes Bay in the north down to North Otago, the duration and intensity of summer drought is unpredictab!e and variable. Within this region, winter temperatures are generally high enough to allow slow growth of pasture but summer drought can completely halt growth in most years, particularly on the commonly found shallow free draining soils. On these soils, moisture stress can develop very quickly because of the limited available soil water. Nearer the foothills, rainfall is greater and severe moisture stress less common. On sunny aspects in hill country however soils are commonly below wilting point for over six months of the year.
