Soil moisture deficit reduced in some areas

Moisture deficits in Northland and the southern North Island were lower at the end of January in comparison to the beginning of the month. There was some relief for dry soils in Nelson, mid Canterbury, south Canterbury, North Otago, and parts of Southland. Soil moisture availability in the pasture root zone was generally better than at the end of January last year, particularly in the North Island.

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