Preventing post-harvest losses of crops is a challenge for small-scale farmers in the tropics. Agrodok 31 provides information on how to improve storage methods for grains, roots and tubers, fruits and vegetables. This booklet has undergone a major revision since it was first published in 1995. The new edition places less emphasis on the technical facilities available for storing agricultural products, and instead provides more background information on how and why products deteriorate, and how this can be delayed or reduced. In addition to information on storage of the most important staple foods (grains, pulses, roots and tubers), a whole chapter in this edition is devoted to fruits and vegetables. These products are not only important in the diet of a farmer's family; they can also contribute to the farmer's income when brought to the market in good condition.
