I have been collecting low tech, low cost methods for postharvest handling and reducing food losses during harvest, packing, storage, processing and marketing for the last 40 years. Some links to free postharvest tech resources to share via The Postharvest Education Foundation (www.postharvest.org):
Free Book: 100 under $100: Tools for reducing postharvest losses.
