Storage methods[edit]
In developed countries proper refrigeration technology is used to keep sweet potatoes for long periods of time. Many poor farmers do not have access to refrigeration or even electricity so must rely on other storage methods. There are several methods of storage that only require simple and cheap building materials. The most commonly used are pit storage, clamp storage and indoor storage. These techniques are used only sporadically however as most farmers practice sequential harvesting in which tubers are left in-ground until needed.[4]
