Tomatoes require fertilizer to grow well. One of the most effective is fertilizing tomatoes with ammonia. But not everyone knows what it is used for and how to do it right. Consider the options for using this fertilizer.

The benefits of ammonia and
At the initial stage of development of any culture, nitrogen is required for growth and gain of green mass. This microelement plays an important role in the formation of chlorophylls, without which photosynthesis is impossible. A sufficient amount of nitrogen will ensure intensive development of stems and leaves, and subsequently will give a good platform for flowering and fruiting.
Features of such a fertilizer
Ammonia (ammonium hydroxide solution) is an ammonia solution, its concentration is 10%, and the amount of nitrogen is 80-82%. Nitrogen in it is easily digestible. What gives this fertilizer an advantage over other nitrogen top dressings such as:
- ammonium nitrate;
To break down the trace elements in them, it takes time from three weeks to several months. The ammonia solution is affected immediately. Nitrogen in this fertilizer is volatile and does not pollute the soil, this fertilizer is environmentally friendly and safe.
When fertilizing is needed
For tomatoes, it is used as the main nitrogen fertilizer during and after seedlings. landings. And also contribute in case of nitrogen deficiency.
It is easy to determine the lack of nitrogen without additional analyzes on the appearance of the bushes. The main signs of deficiency:
- pigmentation changes;
- thin stems;
- leaves are small and irregular in shape;
- lack of growth.
The first sign of nitrogen deficiency is the pallor and yellowing of plants. The loss of saturated color will be observed both on the leaves and on the stems. And also with nitrogen starvation, the stems become thin, lose their elasticity, easily bend under weight, often break. Bushes grow with small leaves, with an irregular shape. Tomatoes slow down or completely stop growing. All this indicates a lack of trace elements, namely nitrogen, and requires an immediate solution to the problem. It is important that tomatoes get nitrogen as quickly as possible for recovery and development.
It is important to remember that an excess of nitrogen can also lead to negative consequences. It is important to comply with the measure.With an excess of nitrogen, the following symptoms are observed:
- lack of flowering;
- defeat of fungal diseases.
Feeding with ammonia in different growth periods
Tomatoes respond very well to ammonia top dressing. Its use will prevent the improper development of culture. It is very important to provide seedlings and adult bushes with a sufficient amount of nutrients. Balanced nutrition of tomatoes plays an important role not only in growth and fruiting, but also in the resistance of plants to diseases.
This is an active highly concentrated fertilizer that requires the right dosage and the intervals between applications.
Top dressing seedlings
The first step in growing seedlings is the preparation of seeds and soil. To prevent infection with fungal diseases, it is worth processing the seeds. A weak 1% solution of ammonia copes well with this. Seeds are washed with such a solution, and then sown in the substrate. This not only disinfects the planting material, but also stimulates the germination of seeds.
The grown seedlings at home often look weak and fragile, very difficult to tolerate the transplant, and take root for a long time in a new place. And as a result, the time of flowering and fruiting comes later than the appointed time.To avoid this situation, it is advised to feed the tomatoes.
Such dressing for seedlings is enough to be done once. The best time to feed the plants is two weeks after a dive. In a bucket of water (10 l) add 2 tbsp. l (20 ml) ammonium hydroxide solution. Pour the seedlings with a solution. For one bush, 2-4 tbsp is enough. spoons.
The effect is observed very quickly. Seedlings grow well, become strong, leaves acquire a deep green color. It easily transfers the transplant to a permanent place.
Top dressing in open ground and greenhouse
Adult tomato bushes require nitrogen top dressing before flowering. This will provide growth, resistance to changing weather conditions. Healthy plants are also less susceptible to diseases and pests.
Tomatoes are fed with ammonium hydroxide solution in open ground and greenhouses twice every two to three weeks. For 10 liters of water, 2-3 tbsp is enough. l ammonia. The solution is watered with bushes. About 1 liter is enough for one adult bush. After nitrogen dressing, tomatoes should be fertilized with phosphorus-potassium fertilizers. But not earlier than 10 days after nitrogen.
Ammonia has proven itself in cases of nitrogen deficiency. At a time when tomatoes require immediate recharge. Easily digestible nitrogen in ammonia, allows you to quickly cope with the problem. One week is enough to see the effectiveness of this fertilizer.
Fertilizer for fruit ripening
Nitrogen in a solution of ammonium hydroxide has the ability to stimulate fruit growth and accelerate the ripening of the crop. This feeding is carried out at the beginning of the formation of tomatoes.
Prepare the mixture by mixing 10% solution of ammonium hydroxide 10 ml, apple cider vinegar 200 ml and 10 ml liquid soap in one bucket of water. The solution is mixed well and the fruits are sprayed. In addition to stimulating ripening, such a cocktail will protect tomatoes from pests.
Ammonia in pest control
They use 10% ammonium solution not only as a fertilizer, but also practice treating them with plants from pests. It copes well in the fight against aphids, which often affects nightshade.
For spraying plants they prepare a solution with 10 liters of water and 2 tablespoons of alcohol, use household soap as an adhesive, rub it on a grater and add it to the solution. Mix and spray the bushes well. This gentle method will help to easily cope with the pest and will not harm the plants.
The advantages of fertilizer with ammonia can be attributed to its easy accessibility and ease of use. As well as the quick action and effective provision of tomatoes with necessary nitrogen. Properly performed top dressing is the key to plant health and high yield.
