The demand for a seasonal product, potatoes, remains high throughout the year. If the conditions in storage areas are not observed, the tubers lose their taste and quality, become soft, wrinkled and dark. It takes a lot of work to grow a good potato crop.

It is also important to provide him with comfortable conditions for proper storage. After all, potatoes must retain their nutritional and taste properties until the next harvest, because we use them for food all year round. When stored properly under the right conditions, this is not very difficult to achieve. Therefore, before storing a vegetable, everything should be taken into account. Preparing potatoes. Long-term storage of potatoes in an apartment in winter can only be ensured by proper preparation.

Conditions

Temperature

The most suitable temperature for storing potatoes (at any time of the year) is 2-3 degrees Celsius. At this temperature, it is at rest, that is, roots do not grow and nothing freezes.

If the temperature is higher, the tubers will begin to "wake up" and prepare for spring planting.

The process of "awakening" potato tubers:

  1. Eyes wake up.
  2. Sprouts grow.

And in the peel (in the upper layer), solanine (a toxic substance) begins to accumulate. If the temperature is close to 0 degrees, then this will significantly affect the taste of the potatoes. It will have a sweetish aftertaste that can spoil the taste of any dish.

This is due to the fact that starch turns into sugar at a low temperature, while slightly frozen potatoes begin to deteriorate very quickly.

Air humidity

Air humidity requirements for storing potatoes:

  • The optimum moisture content should be maintained at the level of 80 - 85%, with such parameters the tubers will not "dry out", that is, they will not lose their weight during storage.
  • In dry air, the taste of potatoes deteriorates, the tubers become dry and lethargic, and the juiciness disappears.
  • If, on the contrary, there is too high humidity in the vegetable store, then fungal diseases and decay of root crops are possible.

Others

Conditions for storing potatoes:

  • Ventilation must be ensured.
  • It is not allowed to cement the bottom of the vegetable store, cover with a floorboard, linoleum and other similar materials, because moisture will easily accumulate and mold will gradually appear. It is best to cover the bottom with sand, or fine gravel or pebbles (materials that absorb moisture well).
  • Two weeks before laying the tubers in the vegetable store, it must be disinfected. After any treatment, the storage must be closed for two days and then thoroughly ventilated.
  • Potatoes should not be allowed to be exposed to direct sunlight, because of this, it will begin to accumulate toxic glycoside (turn green) in itself, it will no longer be possible to eat it.
  • No "neighbors" are desirable for this root crop, the only exception can be made for beets (it is better to spread them on top of the potatoes) - this is a favorable "neighbor".

    Beetroot perfectly absorbs excess moisture, while it does not harm this root crop.

  • If you have to remove rotten potatoes, then you need to remove not only one tuber, but also those that were lying nearby (with close contact, all nearby tubers are infected with an infection, even if they look healthy outwardly).
  • It is necessary to prevent the penetration of various pests into the storage from the outside: rats, mice and slugs.

Difficulties in storing potatoes arise from starch and water, which are found in large quantities in tubers.

Not everyone has a vegetable store, so many will be interested in other ways of storing potatoes: on the balcony, in a box.

Stages

There are several main important stages of storing potatoes in storage, and each of them will require the creation of different modes of humidity and temperature.

  1. First - Immediately after harvesting, it is necessary to sort the potato tubers and dry them. The duration of this period will be approximately 7 to 12 days. The temperature required for this stage should be within 15 - 17 degrees.
  2. Second - this is the so-called treatment period, that is, the period when some damage is healed, as well as the ripening of the tubers. The temperature here needs to be increased to 20 degrees and the air humidity should be ensured within 90-95%.
  3. The third - further, before laying the potatoes for long-term storage, it is necessary to cool it. The temperature should be reduced gradually (by 0.5 degrees every day) and brought to 3 degrees.
  4. Fourth - the main storage period. The required humidity at this time should be maintained at about 80 - 85%. With periodic ventilation, when the indoor and outdoor air is mixed, it is just easy to achieve optimal performance.
  5. Fifth - before you start cutting potatoes, you need to gradually warm up the tubers. This will protect them from unnecessary mechanical damage, since chilled potatoes are quite fragile.

Winter storage methods

In bulk

This storage method is considered to be the simplest because it does not require any special capital expenditures.

There is no need to purchase racks and special containers, since potatoes are simply poured over the entire storage area. The only thing that needs to be ensured is good ventilation.

Typically, this method uses semicircular ventilation ducts.

The bulk method allows:

  • easy to load and unload potatoes;
  • make full use of the entire usable area of ​​the room.

Container way

Pros of this storage option:

  • It is possible to store different varieties of potatoes in one room.
  • The ability to organize gradual shipment to the consumer (throughout the season). After all, containers (in the required quantity) can be partially moved to warm up before shipment, while the rest remain chilled at this time.

How long can stocks last?

The storage duration of the root crop depends on the variety.:

  1. Early potatoes can be stored for no more than 5 months; it is better to use them until December.
  2. Mid-season and mid-late varieties are stored for about 5 - 7 months.
  3. Late varieties are capable of not losing their qualities for 10 months, provided they are kept correctly.

Potatoes should only be stored when they are ripe with a dense skin. Storing potatoes in a cellar or basement is the most common method. It is also recommended to insulate the potatoes with wooden structures from the concrete or brick walls of the basement.

As a result, we can say that if desired, potatoes can be kept safe and sound until next harvest... You just need to make some effort for this. And thanks to modern vegetable stores built using new technologies, automated ventilation systems for root crops, optimal storage conditions are easily created.
