|Abstract: ||The behaviour of Merino wether hoggets grazing an existing
management experiment at Tara Hills High Country Research Station
was studied during summer 1981/1982. The experiment compared three
stocking rates and three management systems (continuous, two
paddock intermittent grazing, six paddock rotational). The daytime
distribution and activity of the hoggets, dung distribution, and Olsen-P
levels of topsoils were recorded on ten altitudinal strata within each of
the nine treatment areas.
Dung frequency was more closely correlated to grazing distribution
than to either resting or total animal distribution. This is contrary to the
generally accepted belief that dung accumulation is associated with
Increasing stocking rate led to a more even grazing and dung
distribution. Subdivision by itself did not improve the evenness of
distribution although it may have enhanced the stocking rate influence.
There was little correlation between dung frequency and soil Olsen-
P levels, especially outside the night camp areas. This indicates the
importance of factors such as plant uptake and herbage consumption in
the phosphate nutrient cycle.
Olsen-P levels were consistently higher in the high stocking rate
paddocks relative to the low stocking rate. Levels in the medium
stocking rate fluctuated between these two.
The implications of these findings in regard to the effects of
intensification of farming in the high country on nutrient cycling and
fertiliser requirements are discussed.|
