PASTURE IMPROVEMENT AND POTENTIAL PRODUCTIVITY IN SOUTHERN NORTH ISLAND HILL COUNTRY

Abstract

HILL COUNTRY is characterized by its steep slopes, differences in aspect, and variability in microtopography. The soils are often shallow, and erosion through slipping and slumping a serious problem. Because of the steepness of slope, most hill country cannot be cultivated and improvement must be brought about by oversowing and other management practices. New Zealand is characterized by such country throughout its length. However, this discussion will be limited to hill country located in the mild, humid areas comprising the southern half of the North Island.
