Information for agriculture from regional geochemical surveys: the example of soil pH in the Tellus and Tellus Border data

The variation of pH of pasture soils across the Tellus and Tellus Border survey area has been analysed. Geostatistical methods allow us to quantify the uncertainty in mapped soil pH and its implications for the health and management of pasture soils. Soil pH indicates that there is a widespread requirement for liming of pasture soils across the area. We exemplify how the uncertainty in statistical predictions can be communicated to a general audience using a verbal scale.
