Ammonia for onions: how to water and feed?
To get a bigger harvest of vegetables, sometimes gardeners use unusual means. Such is ammonia for onions. Although it is considered a medicinal product, it effectively fights the pests of this plant, and is also a source of nitrogen.
The benefits of ammonia: in what cases is it used?
Ammonia is a 10 or 25% ammonia solution and is used as a source of nitrogen. The use of this fertilizer stimulates the rapid growth of onions. The growth of plants is activated and their productivity increases. Onion feathers become juicy and bright green due to nitrogenous dressings.Here it is important not to forget about potassium and phosphorus, and to prevent excessive nitrogen application.
Although people often call ammonia ammonia, but this is not entirely true, since the first substance is ammonium hydroxide dissolved in water, and the second is its nitrate. Ammonium chloride is not used in agricultural activities.
When the feathers of plants either turn yellow or turn light green and the tips turn white, this indicates a nitrogen deficiency. In this case, experts recommend watering the onion with ammonia. This fertilizer can quickly improve his condition. Such top dressing for plants is an ambulance. It is also used to repel insects, thanks to its pungent and unpleasant odor.
Ammonia has an additional advantage - it has a stable connection, and in the garden it is not washed out by rains from the soil.
Ammonia is food and medicine for bulbs in one preparation.
Ammonia as fertilizer for onions
Plants are recommended to be watered with a diluted substance under the root system or to irrigate their green part. Sprayers should not be used, as the substance will be sprayed, and the bulbs will receive very little benefit. The best option would be a watering can. Well, if it has holes of medium size.
There is an opinion among gardeners that it is difficult to overfeed bulbous plants with ammonia, and introducing into the soil does not pose a threat to the accumulation of nitrates. But this substance is caustic, and its high concentration can do more harm than good. Negative consequences may occur as follows:
- green mass activates its growth to the detriment of bulb development;
- there will be a favorable environment for the reproduction of putrefactive microorganisms.
Therefore, you need to know the application rate of the ammonia solution. Timeliness and the right amount of fertilizer are very important for the abundance of the future harvest. After all, feeding onions with ammonia is easily absorbed by plants and ensures the formation of large heads.
How to dilute ammonia for irrigation?
To feed onions, dilute ammonia in the correct proportion so that there is no excess of the substance. It is due to the condition of the plants:
- So, if we feed in case of a serious nitrogen deficiency, then against yellowness, the plants will receive the maximum dose of diluted ammonia. In order to water the onion, take 1 liter of water and pour 1 tablespoon of the substance into it.
- For preventive purposes, you need to use a solution of a lower concentration - just take 2-3 tablespoons of the product, dilute it in 10 liters of water and water the plants.
- If there is a need to use foliar irrigation, then the composition is prepared from 1 bucket of water and 4-5 tablespoons of the drug.
You need to prepare the solution in the fresh air, or in extreme cases in a well-ventilated area.
To prepare the solution, take a pharmaceutical preparation of 25% concentration. Dilute ammonia with water, and do not forget to mix thoroughly.

Onion crops have such pests:

- Medvedka;
- shallot aphid;

Processing onions with ammonia is a very effective measure against each of the listed pests. All thanks to the pungent smell of this substance and therefore there is no need to use drugs that have a greater degree of toxicity.
For effective pest control, onion feathers are treated with ammonia and soap. Prepare the solution like this:

- Pour it with dill (1 liter), and infuse until completely dissolved, stirring thoroughly.
- Add 50 ml of ammonia to this solution.
