LESSON 60
Storage of perishable products is an economic necessity.
Storing in the Field. Field storage , in trenches and pits and by mounding on the surface of the ground, is still practiced to some extent. Trenches are used for storing cabbage and celery, pits for cabbage, turnips, beets, carrots, parsnips, potatoes, and sweet potatoes. All the crops mentioned, except celery, are sometimes placed in piles on the ground and covered with hay, straw, or other severe freezing. This method is known to be satisfactory.
The main disadvantages of field storage are: 1) the temperature and moisture cannot be controlled, hence under unfavorable climatic conditions large losses are likely to occur,
2) the product can be removed only with difficulty when the ground is frozen, and this may prevent marketing at the time desired, 3) the products not removed may be injured when the pit or mound is opened during cold or wet weather, and 4) the labor required to store and remove the products from pits or mounds is large. During the time vegetable products are removed from field storage the weather and the soil conditions are usually unfavorable for such work.
Storing in Cellars. The ordinary house cellar is used to a considerable extent for the storing of root crops. If it contains a heater, this is one of the poorest places in which to store vegetables, as it is likely to be so warm and dry that the products will shrivel. However, by partitioning off a room, which can be kept cool and fairly moist, the house cellar is satisfactory. The storage room should have an opening to the outside for ventilation. The better is the ventilation, the more satisfactory are the results.
Outdoor cellars, made especially for storing root crops, usually give better results than the house cellar. With proper construction the temperature and moisture can be controlled to some extent. This type of storage structure may consist of a pit with a gable roof covered with sods or soil, or a more elaborate structure. Some of the more elaborate are built in a depression or ravine and covered with soil except at the ends. The structure built into a sidehill, or in a ravine and covered with soil, is preferable to the pit type since the soil on the sides and top prevents rapid changes in temperature. In any case the entire structure should be well insulated, and one always wants the exposed end to face the South.
Storage cellars are best suited to the storage of beets, parsnips since these products keep best where the humidity is relatively high. These vegetables were mostly of good quality after having been stored under such conditions.
