It is almost impossible to grow a good harvest of tasty tomatoes without using fertilizers. Tomatoes as they grow make the soil poorer, ripening fruits absorb all the nutrients, so they constantly need micronutrients. To compensate for their shortage will help the application of complex fertilizers in the soil.
Gardeners and gardeners have been struggling for a year to find suitable fertilizers for their tomato beds. There are many dressings for tomatoes both organic and chemical origin. Our article will help save time and nerves, as well as increase the yield of tomato bushes.
What it is?
Complex fertilizer for tomatoes is a mixture in which the three essential nutrients necessary for them are present:
- Nitrogen. It is the basis of plant immunity.
- Phosphorus. Thanks to this component, the root system fully develops (read more about phosphate fertilizers for tomatoes here).
- Potassium. Substance to improve the taste of the fruit.
They also have other trace elements that are necessary for a particular vegetation stage of a tomato:
- copper;
- iron;
- zinc;
- calcium;
- magnesium;
- sulfur and others.
Advantages and disadvantages
The advantages of complex fertilizers include:
- high content of useful elements;
- the absence or low content of chlorine ions, sodium and others;
- presence of all nutritional components in one granule;
- getting a great result.
Compound fertilizers have the only drawback is that in comparison with other species they are represented by a not very wide assortment.
Soil composition improvement
Using nutritional supplements, you can make the composition of the soil richer and more nutritious. In an enriched substrate, seedlings will grow much better. As a fertilizer, you can use one of the following types.
Master NPK-17.6.18
As part of top dressing Master NPK-17.6.18 in large quantities there is potassium and nitrogen, and a little phosphorus. Due to this ratio, the plant acquires a dark green color, it is well-growing vegetation. Tomatoes become more resistant to adverse weather, bloom longer and give greater yield. It is recommended to feed at the stage of growth and flowering.
Crystalon
The Kristalon fertilizer contains macro- and microelements that tomatoes need at various stages of their development. Eventually:
- soil composition becomes balanced;
- seedlings grow faster;
- increases the yield and resistance of the fruit to diseases;
- plants tolerate extreme temperature fluctuations and drought;
- the development of green mass and root system is activated;
- Tomato quality is improving.
To feed the seedlings, foliar feeding is done with Green Crystal solution - 1 l of water 1-1.5 g per 1 l of water. drug. After planting it in open ground, it is necessary to process the yellow type of this fertilizer. This will help the seedlings to harden better. The procedure is carried out the first 4 weeks with a solution based on 1 liter of water 1 g. fertilizer. Crystal red and brown root dressings carried out in the second half of the growing season. This will help increase yields and saturate the fruit with potassium. For this 2 gr. drug is dissolved in 1 l. water.
It is noted that this fertilizer lowers the level of negative effects of pesticides on tomatoes. Crystal dissolves slowly in the soil, indicating its long lasting effect.
Important! The types of this fertilizer among themselves and with other drugs can be mixed, with the exception of those in which metals are present.
The best growth promoters for seeds
Among biological products that are distinguished by high efficiency and environmental cleanliness, popular:
- "Zircon";
- "Humate";
- "Appin".
Proper use of seed growth activators hardens and strengthens seedlings. This affects the yield and resistance to all sorts of diseases.
Zircon
Thanks to Zircon growth stimulator, seed germination increases by 19–23%, and seedlings themselves appear a few days earlier. Seeds for 6-8 hours are kept in a solution that is prepared as follows - 2 drops of “Zircon” are added to 100 ml of water.
Humate
When processing the solution Humate yield is increased by 60%. It must be prepared in advance - for 10 hours. For this 10 gr. drug diluted in 3 liters. hot water. If it is necessary to accelerate the germination of seeds, then 500 ml of the finished concentrate is diluted in 4.5 liters. water. The seedling is treated with the composition - 250 ml of the concentrate is diluted in 4.5 l. water. Humate is a toxic drug, therefore it is necessary to observe safety measures. 
Epin
This versatile non-toxic agent helps to accelerate the germination of tomato seeds and reduce their nitrate content. Epin is used in minor doses. To soak the seeds in 100 ml of water, 3 drops of the drug are taken. Seedlings a day before it is planted or immediately after planting should be watered with Appin solution - dilute one ampoule in 5 l. water and water only under the root. The drug can be used in the future to strengthen the seedlings.
Tomato seedlings
The quality of seedling material of tomatoes can be judged by its appearance. In a healthy plant, the stem will be thick and short with a violet tinge, the leaves are distinguished by density, and the first brush is low. For seedlings to be good, you need to use special fertilizers.
Nitroammofosk
The composition of Nitroammofoski, which is available in granular form, includes:
- potassium;
- nitrogen;
- phosphorus.
It is used dry or diluted with water. Dry Nitroammofosku in bulk contribute to the ground, and the liquid watered plants. It contributes to an increase in tomato ovaries. For this, a matchbox of this fertilizer is taken on a bucket of water and 500 ml of the prepared solution is poured under a tomato bush. This fertilizer can be applied along with:
- sodium humate;
- potassium sulfate;
- mullein
Burly
Water-soluble fertilizing. Fortress is produced in liquid and dry form. The composition of this fertilizer has all the stimulants necessary for tomatoes, micro and macro elements, for example:
- potassium;
- magnesium;
- nitrogen;
- iron.
This carefully balanced fertilizer should be applied to the ground when watering. The first time to feed with a burly is recommended after the second sheet is formed, and then during the pick. Then you need to fertilize every 2 weeks until the start of flowering. For dressing seedlings in 10 liters of water dilute 2 teaspoons of burger.
Mineral substances for regular feeding
Do not stop fertilizing the already established tomato seedlings. If it is regularly fed minerals, then it will bloom profusely and give a large number of tomatoes. There are special mineral dressings that are recommended for use after planting the crop in the ground.
Kemira Lux
One of such complex fertilizers is Kemira Lux, which contains:
- potassium and nitrogen;
- boron and phosphorus;
- iron and manganese;
- zinc and molybdenum;
- copper.
This fully water-soluble fertilizer is used for surface and root feeding. In order to enrich the earth with nutrients 20 grams. Kemira Lux diluted in 10 liters. water. Apply the finished solution once every 7 days. Using a sprayer, foliar feeding is carried out with Kemira Lux solution - 10 gr. diluted in 10 liters. water.
Mortar
Mortar is a complex fertilizer in the form of white granules.In which all substances necessary for normal growth and development are present, trace elements are in the best ratio for tomatoes.
There is a special effectiveness of this drug for plant nutrition. Plants absorb Mortar quickly. After planting, seedlings of tomato, and later in the formation of fruits, fertilized with a solution prepared in a ratio of 15-25 grams. on 10 l. water.
"BioMaster Red Giant"
It is possible to use BioMaster Red giant fertilizer after the tomatoes are planted in the ground and before their fruiting. This fertilizer contains nitrogen, phosphorus, potassium and others that have a positive effect on growth and fruiting. If this drug is used regularly, then you can get a large number of fruits. BioMaster Red giant helps plants tolerate bad weather.
Only high-quality healthy tomato seedlings are guaranteed to give a rich harvest. And complex fertilizers will help improve immunity and increase vitality. In order for plants to respond, thankful for healthy, abundant and tasty tomatoes, you need to feed up following the instructions on the package.
Attention! All complex fertilizers, including growth activators, must be applied strictly according to the instructions. If you violate the recommendations of the seeds and seedlings may die.
