The primary advantage of preserving any kind of food is that you can eat it or use it for cooking long after it is harvested - for instance for use in times of food scarcity or when a product is seasonal.
In modern times, we are very much used to having any kind of food available at any time, but even as close as a century ago this wasn't a given. Many foods could only grow in spring/summer (fruits) or winter (many cabbages and roots), or were only available during the times when animals had young (veal).
This heavily influenced the choice of diet and cooking for specific seasons, and the only way to extend the availability of such foods was to preserve it in some fashion.
There are quite a few ways of preserving vegetables, depending on the kind of vegetable. Root vegetables like potatoes and carrots, for instance, could easily be kept well for weeks or months by putting them under a layer of soil in a wooden box (as Jamie Oliver has been known to use) while softer fruits could be dried or picked (like raisins and pickles).
This created a new advantage: the process of preserving vegetables (as well as meat and fruit) gave them new flavors, which people learned to enjoy as well. Because of this, food like pickles, apple sauce, raisins and various salted meats and smoked fish have become a main way of eating food, rather than just a way of preserving it.
The ideal salt brine ratio for preserving vegetables is typically around 5 to 8 salt to water.
The ideal brine water to salt ratio for preserving vegetables is generally around 5 salt to water.
