Greater Wellington operates a network of soil temperature and soil moisture monitoring stations as well as soil quality at 118 sites throughout the region. The information collected is important for floodwarning (assessing soil moisture levels for flood models), water management during droughts, and detecting long-term trends in our environment.

Soil quality

The soil quality sites are situated on high quality soils in the region, and under a range of land uses including dairy, market gardens, cropping, drystock, horticulture, exotic forest and native forest. The sites are re-sampled every 3-10 years depending on their land use. Soil samples are analysed for a range of chemical, biological and physical soil properties, which gives important information on the overall health of the soil, and any potential impacts land uses may be having on soil quality in the region.

Soil moisture and temperature

The soil moisture and temperature data are logged on a regular basis (usually every 5 or 15 minutes) and then uploaded to our database via telemetry (radio or cell phone transmission) every 2 to 3 hours. This is "raw data" because it has not been passed through our quality checks. Once it has been checked it is moved to a secure archive and is referred to as "archived data".

The data we provide for this website is a combination of archived and raw data. The archived data is shown in black and the raw data is shown in red. This ensures that the data we are providing is as accurate and up to date as possible. Should you require the information in a form other than how it is presented here, please contact us and we can usually provide it within two working days.
