Show Study of Common Types of Storage for Apples A study of common types of storage for apples was recently made by a group of 33 farmers, their families, county agents, and specialists from the New Jersey State College of Agriculture. Agri-culture. Two points of chief interest were storage houses at Marble Laboratory, Inc., Canton, Pa., and at Pennsylvania State college. At these places the visitors had an opportunity to inspect above-ground storage houses and bank or cellar type storage. It was made clear that the principal factors Involved In-volved in storage are ventilation, humidity, hu-midity, and temperature. Apples continue respiration after harvesting and therefore must have air. This is best supplied by large doors at both ends of the storage. The visitors were shown that by opening open-ing the end doors an entire change of air may be made In a short time. In the fall this is done at night when the air Is cool. A good temperature for keeping apples is maintained in this way. In winter the warm day temperatures temper-atures are used for ventilation. The bank or cellar storages hold in uniform temperature without danger of freezing the fruit, as they have the moderating effect of the ground. It was observed that above-ground storage stor-age must be well insulated to hold heat in the winter and to exclude it In the warmer months. Humidity is . generally maintained naturally in cellar cel-lar storage, due to damp earth floors. With other types of Uoors, in cellar or above-ground storage, humidity ia , provided by sprinkling the floor with water at frequeut intervals. ; i , |
