  2. 2. Principles<br />Metal silos are containers made from sheet metal for storing food<br />They can be made in different sizes: 1 to 20 bags of maize<br />The silos are sealed and soldered airtight<br />The silo has two openings: <br />one on the top for filling<br />One on the bottom for emptying<br />
  3. 3. Use<br />Maize needs to be dry (13.5%)<br />Before closing, the oxygen is burned with a candle<br />Covers are sealed with rubber bands<br />The silo is kept undisturbed for 30 days, so all insects die<br />After 30 days, maize can be used<br />
  4. 4. Advantages<br />Reduction in insect damage and losses<br />Reduction in aflatoxins<br />LGB does not destroy storage structure<br />Insecticides are not needed<br />Storage protects farmers against price fluctuation<br />Surplus can be sold at a higher price<br />
  5. 5. Economics<br />Cost; depends on the size:<br />1 bag silo: KShs 3000<br />5 bag silo: KShs 8500<br />20 bag silo: Kshs 22,000<br />Benefit (Kiritiri, 2010-211)<br />Maize price at harvest: KShs 800/bag<br />Current price: KShs 1600/bag<br />Farmer hopes to sell surplus at KShs 2000/bag<br />So cost can be recovered in one season<br />
