Fig. B7.2.1. Interactions between soil (ECa), slope (Sl), aspect (expressed as degrees from north, fN) and the concentration of berry rotundone over three seasons (2012, 2013 and 2015) in a 6.1 ha vineyard in the Grampians region, Victoria. The position of the north arrow is approximate only. Here ECa denotes bulk soil electrical conductivity (mS/m) (see Chapter 4 ‘Direct assessment of soil health – Preparatory work’). Numbers in the legend are the cluster means obtained when k-means clustering is used to cluster individual map layers for each attribute; values for ECa followed by different letters are significantly different (P = 0.05). Redrawn by Dr Rob Bramley (CSIRO) from the data of Scarlett et al. (2014) and Bramley et al. (2017).
