Current Research Summary
Precision Viticulture – The role of soil properties and microclimate in driving within-block variability in grape yield and quality
Precision Viticulture is the management of within-block variability in vine productivity. This project uses modern Precision Viticulture techniques to look at the factors driving within-vineyard variability in grape yield and quality. The spatial variation in yield and quality was identified in three case study vineyard blocks in the Yarra Valley, Mornington Peninsula and the Strathbogie Ranges over the period of 2003 to 2005. The project focus is to determine the primary factors driving the spatial variability in vine productivity. The major role that soil and climate play in defining vine productivity on a regional scale is well studied but little is known about their variability on a single vineyard scale. The extent and spatial structure of both the soil and climate characteristics have been identified in the three case study blocks The relationship between the spatial patterns of the vine productivity and environmental variables have then been investigated using geostatistical techniques such as Geographically Weighted Regression and k-means clustering.
