An automated method of determining tree water status would enable tree fruit growers, foresters and arborists to reduce water consumption, reduce orchard maintenance costs and improve fruit quality. Automated measurements could also be used to irrigate based on need rather than on fixed schedules. Numerous automated approaches have been studied; all are difficult to implement. Electromagnetic sensors that measure volumetric water content can be inserted in tree trunks to determine relative changes in tree water status. We performed automated measurements of dielectric permittivity using four commercially available electromagnetic sensors in fruit tree trunks over the 2016 growing season. These sensors …

Pruning means removing certain parts of the tree in order to regulate the shape and bearing habits of the tree and quality of the fruit, but with a minimum of interference with natural growth habits. Not all kinds of fruit and nut trees are trained and pruned the same way, but most fit into one or more of the basic systems. To be able to prune intelligently, one must understand the basic principles. It is the aim of this bulletin to present basic principles and methods of pruning young and old fruit trees, vines, and bushes.
