SALT IN THE GARDEN – SHOULD I USE OR NOT?
I read in one publication that in August (oh when exactly?) onions, garlic (winter or spring?), cabbage need to be loosened and sprinkled with salt - 225 g per 10 liters of water. Leave the onion and garlic undressed, pour the cabbage on top and dig in again. Why do you need to do this? And is it necessary? Galina Shilova, Kirovo-Chepetsk

Science says that the effect of table salt on the soil is more negative than beneficial, however, many gardeners have been using it for years. Let's figure out whether your garden really needs it.
The formula for table salt is NaCI, that is, it is a compound of sodium and chlorine. Both of them are included in the group of elements conditionally necessary for plants. Sodium increases the accumulation of sugars and winter hardiness, and chlorine is involved in energy metabolism and has a positive effect on the absorption of oxygen by roots.
RџSЂRё When adding table salt to the soil, chlorine is quickly washed out, since its ion is negatively charged. The sodium ion remains and accumulates in the soil, having a detrimental effect on its physicochemical and microbiological composition.
Beetroot, cabbage, onions and garlic need small amounts of sodium, which improves the keeping quality and taste of their fruits. However, it is better to satisfy this need not by watering with table salt solutions, but by fertilizing with potassium fertilizers. After all, sodium and chlorine are present in them as impurities.
Many vegetable growers To combat onion and cabbage flies, water onions, garlic and cabbage with a solution of table salt. Such watering gives a certain effect. However, the concentration of the solution should not exceed 20 g per 10 liters of water.
Plants are able to absorb the elements they need from the soil only if they are in low concentrations. And this applies not only to table salt, but also to all other fertilizers, which are also salts.
RџSЂRё applying shock doses of 225-500 g in the soil will kill all living things responsible for fertility, and in order to correct the situation later, you will have to add large doses of organic matter for more than one year. Therefore, it is more practical to feed all of the above crops with potassium fertilizers at the end of the growing season. This will have a much greater impact on improving the taste and longevity of the crop, but their dose should also not exceed 20 g per 10 liters of water.
In the first half of the growing season, it’s a good idea to feed all garden crops sodium humates. When dissolved in water, they form humic complexes, which act as biologically active substances. They activate the activity of microorganisms, accelerate and regulate metabolism in plant tissues, increase resistance to diseases and adverse factors.
Garlic and onions are raked off the soil from the bulbs in order to free them from dense soil, in which it is simply physically difficult for them to grow. The released heads gain more mass noticeably faster and ripen better. This procedure begins 20-30 days before harvesting, for winter varieties - at the end of June - early July, for spring varieties - at the end of July - beginning of August. The soil is raked from each bulb so that the head sticks out halfway from the soil.
It is also recommended to hill up cabbage, regardless of whether you fed it or not. Early - once or twice a season, and middle and late - three times. This is done so that the cabbage grows additional roots. In addition, this technique protects its roots from the cabbage fly. The cabbage is hilled for the first time at the beginning of summer, and the procedure is repeated in mid-July and August.
