Description

Moisture stress is a recognised factor in the persistence of desirable pasture species of naturalised hill country pastures of New Zealand. Two variables in a soil water balance model are examined here for their contribution to maintaining plant cover. Soil water infiltration is not a limiting factor even though these hill country soils will respond to lime and this response is believed to be due to its effect on the physical properties of the soil. However, the effect of microtopography and wind direction does reduce soil water input.
