Evaluating soil and pH mapping locations
Aims

To understand the benefits of soil pH mapping and its interaction with other soil and crop mapsTo compare various layers of information (pH, elevation, EM-38, yield andsatellite imagery) for understanding paddock variability.

Key messages

We focussed on measuring paddock variability rather than implementing an actual variable rate trial. Soil pH mapping proved to be a valuable step towards variable rate lime with significant variability found, pH(CaCl2) varying from 4.0 to 7.1 across a 50ha paddock. A variable rate management approach to pH on this paddock would deliver a 75% saving of lime.
