Soil moisture

Soil moisture on 30 September

Conditions in the North Island were near normal at the end of September, with most areas at field capacity. The area of soil moisture deficit in eastern and northern South Island regions has shrunk slightly, but Marlborough, Canterbury, and Otago are still drier than normal. Western and southern South Island regions are near normal.

Soil moisture deficit in the pasture root zone at the end of September (right) compared with the deficit at the same time last year (centre) and the long term end of September average (left). The analysis is done for an average soil type where the available water capacity is taken to be 150 mm.
