Our NPP provides farmers with valuable insights into their farms through the use of satellite imagery and other data. One of the main metrics used by DAS is Long-Term Mean Net Primary Production (NPP).

NPP is a measure of how much carbon is being absorbed by plants in a given area. It is an important metric for farmers because it can be used to estimate the productivity of their land. The higher the NPP, the more productive the land is likely to be.

The NPP metric used by DAS is designed specifically for annual plant-based systems. It is calculated using a carbon accumulation and turn-over model developed by the CSIRO. The model inputs include satellite derived imagery, elevation, solar insolation, and air temperature.

It is important to note that the type of production system, such as irrigated pasture vs rainfed pasture, can affect the long-term NPP of a farm. If used over plantations or areas of remnant vegetation (woody vegetation), the values will tend to be lower than the values returned for annual plants. The metric is calculated across the whole area of each farm. If a farm has large areas of unproductive land, then it will have a lower overall long-term mean NPP.

DAS NPP provides farmers with valuable insights into the productivity of their land and can be used to make informed decisions about crop and pasture management.
