Nitroammofosk - how to use fertilizer correctly?
Nitroammofoska is one of the most famous fertilizers produced in the form of granules having a pink-milk color. In addition, nitroammophoska promotes the rapid adaptation of newly planted plants in a new place, is able to extend the flowering period of ornamental plants and even increase the winter hardiness of a wide variety of crops. Nitroammofoska is perfectly soluble, and therefore it is often used for foliar top dressing.

Composition and various combinations of nitroammophoski
Nitroammofoska contains 3 main elements necessary for plants - nitrogen, phosphorus and potassium. All of these elements in the nitroammophos are present in easily accessible forms for plants.
The most famous nitroammophoska, in which three basic substances are contained in a ratio of 16:16:16. Such a nitroammophosk has about 16% of each of the main elements, that is, the total proportion of elements useful to plants is about 50%. This type of nitroammophos can be used on all types of soils.
The following type of nitroammophoska with the composition: 8:24:24. This type of nitroammophos is used on soils where there is a deficiency of phosphorus and potassium. The fertilizer is ideal for winter crops, root crops and potatoes, it is often used in regions with a deficit of moisture in the soil.
The following types of nitroammophoski: 21: 0,1: 21 and 17: 0,1: 28 - are used on soils with a deficiency of nitrogen and potassium, but with a sufficient amount of phosphorus.

Benefits of Using Nitroammophoski
- The main plus is a very high concentration of substances necessary to stimulate plant growth, as well as increase their productivity. Relative to the total mass of fertilizer, the proportion of substances necessary for plants is 30%.
- Nitroammophoska is extremely easily divorced in water, which is its undoubted advantage.
- Each nitroammophoski granule has three essential substances - N, P and K.
- It is excellently preserved and, with proper storage, retains its flowability.
- Thanks to the use of nitroammophoski, productivity sometimes increases up to 70% (depending on the crop itself).
Disadvantages of using nitroammophoski
- Along with the undoubted advantages, nitroammofoski also have their drawbacks. For example, not everyone likes that it is a chemical drug.
- With an excessive dose of nitroammophoska, nitrates are guaranteed to accumulate in the soil, they penetrate vegetables, root crops, fruits and berries and negatively affect the human body.
- Nitroammophosk is a combustible and explosive substance, therefore, it is necessary to strictly monitor the storage conditions and keep the nitroammophosk away from fire.
Rules for the use of nitroammophoski
Given the combustibility and explosive properties, nitroammophoska can be stored at a temperature of no more than + 30 ° C. Choosing to save should be rooms built of brick or concrete.
To prevent granules from sticking together, storage humidity should be no higher than 50%.
When fertilizing, be sure to wear rubber gloves and a respirator.
Features of use at home
Nitroammophoska is used both before sowing or planting, and in growing crops. The best results are achieved on sierozems and chernozems, on a sufficiently moist soil.
On heavy soils, it is better to introduce nitroammophoska in autumn, on sandy soils - in spring.
Optimal dosages for different crops
In the autumn period, about 42 g per square meter should be introduced under the excavation of the earth. When processing virgin soil, you should make 50 g per square meter. For greenhouse soil, 30 g per square meter is required.
Under the tomato bushes
The effect on tomatoes is to strengthen shoots, accelerate the growth and ripening of tomatoes. Usually nitroammofosku is applied four times under tomatoes. The first time is in the spring, a couple of weeks after the moment you planted the seedlings in the ground. At this time, a tablespoon of fertilizer should be dissolved in a bucket of water and spend 0.5 l for each plant.
The second top dressing is carried out a month after the first. At this time, nitroammophosk in the amount of a tablespoon should be dissolved in a bucket of water and add 0.5 kg of mullein to the solution. The application rate is 0.6 l under the plant.
The third top dressing needs to be carried out when the third brush of tomatoes begins to blossom. At this time, you need to dissolve a tablespoon of nitroammophoska and a tablespoon of sodium humate in a bucket of water. Norm - 1 liter per plant.
The fourth dressing should be carried out two weeks after the third with the same composition as the third with a consumption rate of 1.5 liters per plant.
Under the potato
Together with the planting of tubers, it is necessary to put a teaspoon of fertilizer and mix it with the soil. The introduction of nitroammophoski in this way will stimulate the growth of the root system of potatoes, improve the growth of the vegetative mass of the plant. It is quite acceptable to water the planted plants with a solution of nitroammophoska. In this case, 30 g of fertilizer must be dissolved in a bucket of water - this is the norm per square meter of soil.
Under the cucumbers
They are fed a couple of times during the growing season. The first treatment is carried out before placing the seedlings of cucumbers in the ground, spending 30 g per 1m2.
The second time, cucumbers are fed before the formation of the ovaries. During this period, 40 g of fertilizer is dissolved in a bucket of water. For each plant, 350 g of solution is consumed.
This culture is fed with fertilizer 14 days after placing the plants on the ground. For feeding, dissolve a tablespoon of nitroammophoska in a bucket of water - this is the norm per square meter of soil.
For oats and other crops
Rye, oats, wheat, corn and sunflowers love nitroammophoska at first when sowing these crops, and then in the middle of the season.
Calculation is carried out per hectare, for a number of crops its own norm, so, wheat needs 170 kg of fertilizer per hectare; for rye, barley and oats - 150 kilograms, for sunflower - 180 kg, for corn - 200 kg.
In the middle of the season, sweet corn and varietal sunflowers are usually fed on the home plot. Norm - two tablespoons of nitroammophoska per bucket of water in terms of square meter of soil.
For garlic and other onion
Garlic is allowed to be fed both under the root and to carry out foliar feeding. Initial feeding is carried out 30 days after the formation of sprouts. Fertilize winter garlic in April, spring - in June. A tablespoon of nitroammophoski must be dissolved in a bucket of water, this is the norm per square meter of the area occupied under garlic.
If garlic plants are sorely lacking in nitrogen, as you can guess by carefully looking at feathers that turn yellow when nitrogen is lacking, you need to feed them by foliar feeding. This fertilizer must be dissolved in water in the amount of one tablespoon, then fill the solution into a sprayer and process the garlic feathers, wetting them as well as possible. Usually, just a couple of days after such top dressing, the effect is clearly visible.
Under garden crops
This fertilizer is perfect for providing the most important elements of fruit trees of different ages and berry bushes.
The first application of this fertilizer must be carried out before planting seedlings of trees and shrubs. The amount of fertilizer usually depends on the age of the seedling and its size. For example, under annuals, about 150 g of nitroammophoska should be introduced into the planting hole, mixed well with the soil so that the roots of the seedling do not come into contact with fertilizer. For two-year-old seedlings of fruit crops, 200 g of fertilizer should be applied, and for seedlings of shrubs that do not differ in large sizes, 100 g of this fertilizer is quite enough.
They respond well to the introduction of nitroammophoski plants at the end of flowering. At this time, 50 g of nitroammophoski, previously diluted in a bucket of water, is introduced under the fruit trees. Under large trees older than seven years, this amount of fertilizer can be tripled.
After flowering, raspberries also need to be fed with a nitroammophos, making it about 40 g in the form of a solution (in a bucket of water in terms of a square meter of soil). Under currants and gooseberries, 30 g of fertilizer is enough, also dissolved in the same volume of water.
If during the growing season a weakening of growth activity in plants is observed, then it is permissible to carry out foliar feeding with a nitroammophos. It is advisable to carry out it no later than mid-summer, you need to dissolve 2-3 tablespoons of fertilizer in a bucket of water and in the evening it is good to moisten all the aerial parts of plants with this solution.
Nitroammophoska helps grapes quite well. In the spring, about two tablespoons of nitroammophoski, previously dissolved in 10 liters of water, are introduced under the bush, and after flowering, foliar feeding is carried out, dissolving a tablespoon in a bucket of water and spraying the plants with this composition, moistening the entire above-ground mass.
Under the flowers
All the most important elements that nitroammophosk contains are necessary for flower crops. Thanks to the nitroammophosque, it is possible to achieve magnificent and long flowering.
It is permissible to carry out the very first top dressing with this fertilizer after a couple of weeks from the appearance of seedlings above the soil surface. Both annual flower crops and perennials need to be fed with nitroammophos dissolved in 10 l of water in an amount of 30 g per square meter occupied under flowers.
Re-flowers can be fed during the formation of buds, increasing the amount of nitroammophos, dissolved in a bucket of water, up to 40 g in terms of square meter of soil occupied under the flowers.
The third time, to extend the flowering period, the flowers can be fed at the height of flowering by dissolving 50 g of nitroammophoska in a bucket of water and watering this solution with a square meter of soil occupied under the flowers.
Nitroammophosk is also necessary for home flowers, here you can get by with one foliar top dressing in the spring, dissolving two tablespoons of nitroammophosk in a bucket of water and moistening the aerial mass well.
Conclusion As you can see, nitroammophoska is an excellent universal fertilizer that is necessary for fruit, berry, and flower crops. Of course, like any other fertilizer, nitroammophosk needs to be used in the optimal time and in the optimal quantity - we have all figured this out. If you do everything right, then neither plants nor yourself can be harmed.
