The document discusses precision viticulture techniques at the Department of Agriculture Food and Environment. It covers collecting and analyzing vineyard data, using variable rate management, estimating grapevine biophysical parameters like pruning weight and canopy volume, and monitoring grapevine water status through field observations and sensors to implement precision agriculture practices.
