Management classes and data consultation

Data layers gathered using PA tools are analysed to form within-paddock management classes.

Using management classes is an interim step towards full variable-rate treatment of paddocks. Our research has allowed us to ascertain optimal methods for analysing a number of layers of information about a paddock and distilling zones of similar yield response. The data layers may be from a number of different sources, or multiple years of crop yield. It is important that some crop yield information is included as this is the production indicator in which ultimately we are all interested.

This process is the first step towards managing operations based on PA information. Class delineation relies on the accuracy of the mapped layers so that significant differences across a paddock can be reliably identified. The ACPA has devised techniques to perform these operations on data from your paddocks.

The ACPA can analyse data that you already have archived, or help you gather more layers of information. Ultimately we will provide you with an analysis regarding the potential to delineate production classes in your paddocks along with production class maps in digital and hard copy formats.

These classes may then be strategically sampled to find differences in soil physical or chemical properties that could provide opportunities to manage the paddock using variable-rate technology (VRT).
