Determine which fertilizer for tomatoes in the greenhouse is better
Why is it necessary to introduce fertilizers?The main goal of the event is to get a good harvest, a beautiful appearance and an ideal taste of tomatoes. That each bush gives on a maximum of fruits, it is necessary to provide him with proper nutrition and the whole range of useful components.
Tomatoes are good for adding fertilizing, both to the ground and to the green mass, but this does not mean that they need to be filled with various compounds, and constantly spraying with fertilizers on the foliage. This event should be approached in a measured and accurate manner.
In the process of growing, tomato seedlings need to be fed with substances that necessarily include:
- Magnesium;
- Potassium;
- Copper;
- Bromine;
- Phosphorus;
- Nitrogen;
- Zinc;
- Bor.
Fertilizers are necessary for a good harvest Once the plants have become accustomed to the climate in a hothouse design and begin to grow rapidly, they must be supplemented with solutions containing nitrogen. Also, tomatoes require nitrogenous mixtures during the ovary period. But, with nitrogen, do not overdo it, as it is a stimulator of growth of green mass to the detriment of the growth of juicy tomatoes. For a good development of the roots and the correct aging of the tomato, tomato seedlings need to be fertilized with phosphorus.
Attention!If the air temperature is below +15 ° C, phosphorous additives can not be introduced, since they are not digested, but accumulate in the soil.
For the correct formation and development of fruits, tomatoes require potassium, by the way, fertilize them at this time should be very often. In addition, potassium helps tomatoes to withstand negative effects, diseases and sudden changes in temperature. If the foliage of the plant has curled into a tube, this indicates a potassium deficiency. If tomatoes grow in a hothouse design on sandy and sandy loamy soil, they need to be fed with magnesium sulfate, especially during the formation and ripening of the fruit.
In addition, in most solutions for a tomato must necessarily be:
- Manganese;
- Boron;
- Copper.
Manganese activates the ripening of juicy tomatoes, and boron and copper are needed during the flowering period and fruiting of the culture that is loved by almost all truck farmers.
Tips: how to fertilize tomatoes in the greenhouse
The first top dressing should be done at the stage of planting tomatoes in a greenhouse. To this end, it is necessary to pour in ashes into the dug holes, lay humus or compost, in which there is a huge amount of substances that help tomatoes to grow, develop and excellently bear fruit.
After planting tomatoes in a greenhouse, they do not need to be fertilized for several weeks.
The fact is that for a plant, relocation to a new location is always difficult to transfer, and it is necessary to wait until the seedlings are adapted to the new growth conditions. Therefore, for 14 days it is necessary to give tomatoes a rest, after which it is good to feed organic substances and shed "green tea".Organic ingredients can be easily prepared on their own.
For example, from components such as:
- Plantain;
- Nettles;
- Wood ash;
- Mullein.
The recipe is simple, 5 kg of greenery should be crushed, add 250 grams of ash and a bucket of Mullein, mix and leave for 48 hours. The resulting composition is diluted in 100 liters of water and spills about 2 liters of liquid for each tomato bush. If there was no organics at hand, there is no need to panic - the complex, mineral fertilizer bought in a specialized store is perfect. After 14 days, you need to feed again.
For the second feeding, mineral fertilizers are applied, which include:
- Nitrogen;
- Phosphorus;
- Potassium.
Under each bush poured 1 liter of the finished solution. Then tomatoes are fertilized with potassium sulfate, then when tomatoes start to bloom actively. For this top dressing it is necessary to prepare a solution consisting of a spoonful of a solution of nitrogen, phosphorus and potassium plus 0.5 liters of liquid mullein and poultry manure. The composition should be diluted in a bucket of water. Under each tomato bush poured about 1 liter of solution.
Every tomato bush needs to be fertilized in a greenhouse
When tomatoes start to form ovaries, they will not be prevented from feeding such a composition: 10 g of boric acid and 2 liters of ash should be mixed in 10 liters of boiling water. The finished composition should stand for 24 hours, after which they need to pour tomatoes 1 liter per each bush. In this composition, there are many minerals that provide healthy growth. The last time tomatoes are fertilized during active wearing of fruits in order to provoke maturation and improve the taste of tomatoes.
The root system of plants should be watered with such a composition: in 10 liters of water, one must mix in liquid sodium humate and 2 tablespoons of superphosphate. This is only an approximate instruction how to perform a radical top dressing of tomatoes in a greenhouse.
Professional gardeners, engaged in the cultivation of all favorite crops, rely on personal experience and take into account individual conditions. In addition to radical top dressing, tomatoes are very popular when they are sprayed with various useful solutions.
Foliar fertilizer helps tomatoes get those useful elements, which are in short supply in the ground. The fact is that the tomato foliage absorbs only those components that it needs, so perhaps they are not afraid of excessive overfeeding. In addition, spraying the green mass gives more immediate results, which are visually visible only 5 hours after the event. And when you bring in the necessary minerals under the root system, the results can be seen only after 14 days.
Do manure for a tomato greenhouse
Manure has a characteristic aroma and consistency. The product is often used as a fertilizer. Manure is organic, which consists of livestock excrement.
Manure is used as fertilizer for the tomato
Namely:
- Cow;
- Goat / sheep;
- Horse;
- Pig.
The preparation of land in a greenhouse construction is of great importance, affecting the yield. The greenhouse is heated by manure in the early spring. If you find a fresh product at this time did not work, you can try not to use it.
Why use iodine for tomatoes in a greenhouse
Every year gardeners use iodine for tomatoes as a fertilizer. Usually, iodine is used for tomatoes in the open ground or in a greenhouse, as well as for watering a tomato seedling.
Iodine is used for tomatoes in the open ground or in the greenhouse
How to understand what iodine needs to be fed:
- Deficiency occurs during the period of the disease.
- First of all, the deficiency of the element affects the number of fruits. This applies not to young bushes that do not begin to form fruits. If you do not timely respond to the problem and do not enrich the land with iodine solution, then the harvest can not be obtained at all.
- You can also notice a decrease in the immune system in plants. This is a very difficult condition for not mature tomato seedlings, which leads to the development of diseases and even the death of seedlings. Iodine deficiency can become the main cause of regular diseases.

If late blight develops, root rot, mosaic or brown spots appear, this is the first signal that it is time to make iodine or siderates. If the problem persists, the plant may die. Timely and properly fertilizing, you can get the richest harvest of juicy, delicious tomatoes.
