Top dressing of a tomato in a greenhouse: when and what to fertilize?

In some Russian regions, the mostThe optimal conditions for growing tomatoes are greenhouse. There they grow better and are pleased with large harvests. However, this is a very time-consuming task, because if you do not take appropriate measures in time, this culture is much more often affected by illnesses.

As a rule, the heat of vegetables in the greenhouse is usually enough, so the main attention requires the top dressing of the tomato in the greenhouse.

Sometimes tomatoes grow well, but at the same timeDo not bloom. They only strenuously develop their stepchildren. In this case, such a top dressing of a tomato in a greenhouse, like phosphoric and potash. In some cases, wood ash as well as half a glass for each bush is also effective.

Most of all top dressing of tomatoes in a greenhouse is necessary during the flowering period and when fruits are formed. There are often cases when the bushes have an abundance of fruits, but they do not ripen.

To speed up the browning process, manyresort to a procedure such as foliar top dressing of a tomato. For this, superphosphate is used. The composition is prepared as follows: forty grams of the substance (or approximately two matchboxes) are dissolved in one liter of hot water, left for a day, and then diluted with nine liters of water. Many are interested in the question of how to recognize what the tomatoes lack and how to help them.

I must say that sometimes this questioneven specialists are unable to answer. If the bush is large, there are a lot of dark green leaves on it, then it means that the top dressing of the tomato in the greenhouse was done with fresh manure and it's no longer worth pouring on it.

And it can be the other way round: the bush grows poorly, there are pale leaves on it. In this case it is necessary to use nitrogen fertilizers - urea, nitrate, and it is better in a complex.

Often on seedlings or on the trunk appearspurple hue. This is a consequence of a lack of phosphorus. Although usually it is in the soil, but for some reason poorly absorbed. If there is too much phosphorus in the soil, the leaves on the bushes begin to turn yellow or twist. This means that the next top dressing of tomatoes in the greenhouse should not contain this element.

In general, the cultivation of vegetable crops in greenhouse conditions assumes the existence of a certain calendar, which indicates the periods of work carried out, including the introduction of fertilizers

The first top dressing of tomato in the greenhouse is carried out onthe eighth day after planting. Shrubs under the root are watered with a solution of mullein from the calculation of one part of the fertilizer for ten parts of water. The consumption of the solution is calculated from the ratio of one liter per bush. Root irrigation requires caution, so as not to erode the soil.

The next feeding is necessary only after twenty days. In addition to the solution from the mullein, the biostimulator "Ovary" sold in agro-shops is used.

Many experienced vegetable growers believe that the second feeding of tomatoes in greenhouses, in addition to Mullein, should contain potassium and magnesium sulphates, as well as boric acid.
During the beginning of the process of mass ovaries, tomatoes are sprayed with a solution consisting of water with milk, boric acid, iodine and soda ash.
