Characterising spatio‐temporal variation in fruit composition for improved winegrowing management in California Cabernet Sauvignon Open
Background and Aims Spatial variability in yield and fruit composition in winegrape vineyards has been demonstrated, but few chemical compounds responsible for impacting wine composition have been analysed at a sample density high enough t…

Broadacre Mapping of Wheat Biomass Using Ground-Based LiDAR Technology Open
Crop biomass is an important attribute to consider in relation to site-specific nitrogen (N) management as critical N levels in plants vary depending on crop biomass. Whilst LiDAR technology has been used extensively in small plot-based ph…

An algorithm to identify the appropriate size of a neighbourhood when analysing spatially distributed field experiments by local cokriging Open
Farm management decisions based on multiple treatments or yield differences with measurable statistical uncertainty are effective and popular. The "oft" (on-farm-tools) software developed in this study provides an easy access to identify l…

Making sense of a sense of place: precision viticulture approaches to the analysis of terroir at different scales Open
Traditional ‘terroir zoning’ has largely relied on heuristic ‘expert’ opinion coupled with approaches to land classification based on thematic mapping to describe the influence of soil conditions and climate on wine composition. Recent adv…
