Azofoska fertilizer is widely used in agriculture on an industrial scale, as well as in the home by summer residents and gardeners. This is a complex fertilizer, balanced in its composition. The composition of azofoska is suitable for all types of soils, because it has a neutral effect. It can be used for both fruit and vegetable crops and ornamental plants.
Description
Azofoska is made in the form of non-hygroscopic granules of 1 or 5 mm, convenient to use. The color can be either white or pink. The structure of the substance is crumbly and does not cake during storage. In the soil, the granules quickly dissolve and are absorbed by plants, are firmly held in the soil and are not washed out by water.
Azofoska is non-toxic, completely safe and non-flammable. Azofoska is packaged in vacuum or tightly closed bags. Damage to the packaging leads to loss of beneficial properties, so it must be stored in proper conditions.
The effect of application is more noticeable when fertilizing clay soils and sandstones, since chernozem contains many nutrients.
The drug is produced in different percentage combinations of ingredients, so when purchasing you need to look at the composition of Azofoska:
- nitrogen;
- phosphorus;
- potassium;
- sulfur.
Nitrogen is the basic component of the drug. In Azofoska its amount can range from 16 to 26 percent. Nitrogen is necessary for seedlings to ensure metabolic processes and the synthesis of plant protein.
Phosphorus activates the growth of seedlings; it is necessary at the beginning of the growing season. The percentage composition in Azofoska varies from 4 to 20 percent.
Potassium regulates metabolic processes, the formation of the root system and fruits. The shape, taste and color of the fruit also depend on the presence of potassium in the soil. Potassium deficiency affects plant resistance to weather conditions and diseases. The percentage in Azofoska ranges from 5 to 18 percent.
Sulfur regulates photosynthesis, corrects the content of nitrates, essential oils and essential acids. Azofoska contains little sulfur, but this amount is quite enough to maintain the necessary processes.
Note! Nitrates are essential for plant health; in small quantities they do not pose a threat to the human body.
Effect of using fertilizer:
- protects plants from diseases;
- increases the productivity of fruit and vegetable crops;
- provides fruits with healthy fats, which has a beneficial effect on yield;
- prolongs the flowering of plants;
- improves the quality of fruits and vegetables;
- increases the shelf life of fruits and vegetables;
- helps increase nutrients in fruits.
The use of Azofoska allows you to harvest a good harvest at minimal cost.
Azofoska fertilizer refers to complex soil fertilizing, which contains all the necessary elements - phosphorus, potassium and nitrogen (NPK). This combination provides plants with all the beneficial substances.
Azofoska is easily absorbed by plants. The absence of ballast substances ensures dissolution in liquid without sediment.
Application
When should you apply fertilizer? Each plant requires fertilizing at different times. General recommendations are as follows:
- in the fall after digging the soil;
- in the spring before planning planting;
- before planting the plant in a hole;
- when sowing seeds.
Heavy soil is fertilized in the fall after gardening is completed, light soils are additionally fertilized in the spring.
Important! An excess of fertilizer will negatively affect the taste of the fruit.
Remember that the use of Azofoska must be regulated by the instructions. The root system will take the required amount of nitrates, the remaining nitrates will end up in the fruits.
An important rule for using agrochemicals is to alternate them with organic ones: every third year it is necessary to replace Azofoska with ordinary humus. However, it is not recommended to apply manure due to the large amount of nitrates.
Fertilizing in spring has a number of features; for example, it is unacceptable to use Azofoska in unheated soil. The best time to feed is May. In the fall, it is advisable to use Azofoska no later than the first days of October.
Proportions
In retail trade you can find different combinations of the mineral composition of Azofoska (NPK). Let's look at them.
For liquid feeding, the following combinations are used:
- NPK in the ratio 16:16:16 is well suited for all varieties of horticultural crops - vegetables, tubers and fruit trees. For continuous fertilizing of the soil, calculate 1-2 tbsp/l x sq.m. To feed fruit trees, apply 2-3 tbsp per tree, deepening it into the loosened soil. For vegetable seedlings - half a teaspoon per hole. Potatoes are fertilized twice - after the first shoots and after the flowers set (2 tbsp/l per sq.m.).
- NPK in the proportion 19-9-19 is used for soil enriched with phosphorus. This proportion is necessary in regions with an arid climate, in which the top layer of soil is not washed away by rain and melted snow. How much fertilizer should I apply? The same as with the proportion 16:16:16.
- NPK in the ratio 22:11:11 is used for intensive use of soil on an industrial scale. This combination of mineral components is not used in garden plots.
Note! Granules diluted with water can be used to fertilize plants in the summer.
For dry and wet feeding, the following proportions are adhered to:
- 30 or 40 grams of granules per square meter - for feeding annual seedlings;
- 4 grams of granules - for fertilizing the hole before planting seedlings;
- 3 gr. granules per liter of liquid - to feed the root system;
- 30-35 dry granules per sq.m. — for fertilizing fruit trees/shrubs.
Azofoska for feeding fruit and vegetable crops
Let's look at how to properly use Azofoska to feed certain garden plants.
cucumbers
A week before placing the seedlings in the holes, water the soil with diluted fertilizer. Next, the cucumbers are fertilized with organic matter - manure or humus - around the beginning of June. In the middle of the month the chemical is reintroduced. This is quite enough for high-quality ovary and fruit growth. If you decide to introduce an additional portion of fertilizing, excess nitrates will end up in the fruits themselves. This will be harmful to health and spoil the taste of cucumbers. If you still decide to additionally feed the cucumbers, it is better to use a liquid solution - green slurry.
Proportions: for 10 bushes, one ten-liter bucket is used, in which 1 tbsp of agrochemical is dissolved. To enhance the fertilizer, you can dilute a mug of ash in a bucket.
Tomatoes
The first portion of fertilizer is applied before planting seedlings in the ground - dilute a coffee spoon of fertilizer in a liter of water. After a couple of weeks, repeat feeding in the same proportion. Next, you should feed the plants with organic matter. After the buds are formed, Azofoska should be added in the proportion of 25 grams x 10 liters.
Potato
Potatoes are fed once a season - either before planting or after autumn work in the garden. If you fertilize the soil before planting potatoes, 4 grams of Azofoska should be placed in one hole. If you fertilize the soil after autumn digging, apply fertilizer at the rate of 20 mg per square meter.
Grape
To fertilize the vineyard, Azofoska is diluted in a bucket - add 2 tbsp. Feeding is carried out three times a season:
- before flowers form;
- after berry set;
- during the ripening process of berries.
The first two feedings are carried out using Azofoska, the last - with another fertilizer without nitrogen. It prevents berries from ripening.
Strawberry
Berries do not grow well in heavy soil (clay), so fertilizing is necessary for a sustainable harvest. Azofoska is applied only to sun-warmed soil, that is, in late spring or summer.
Important! The introduction of Azofoska into unheated soil promotes the accumulation of nitrates in plant fruits.
How is Azofoska applied to feed strawberries? This can be done directly into the soil between the bushes or by watering the hole with the solution. If you scatter granules near the root system, calculate the proportion - 30 mg per square meter. For watering, use a solution of one tablespoon per bucket of water.
Analogs
Nitroammofoska is an analogue of Azofoska, only with an increased sulfur content. Nitroammofoska should not be confused with Nitroammophos, which does not contain the microelement potassium. A good substitute for Azofoska is and, which contains magnesium, which is important for some soils.
- another analogue, but without sulfur content. The disadvantage of this agrochemical is its instability - it is quickly washed out of the soil.
Azophos is not a plant food, but a protection against pests. Their names are similar, but their purposes are different. However, gardeners also use Azophos to feed seedlings, as it helps increase productivity. Azophos has one more property - it does not accumulate in vegetable crops, fruits and berries.
The composition of Azofoski is optimal for fertilizing any garden crops; it contains all the necessary minerals - magnesium, calcium, copper, zinc and trace elements of Azofoski. It should be remembered that Azophos is toxic, as it is a fungicide. If skin comes into contact with the drug, rinse the damaged area with a large volume of water.
Storage
This fertilizer belongs to the third hazard class, so a number of rules must be followed during storage. With large accumulations of agrochemicals, a spontaneous explosion is possible - this is what distinguishes dust from fertilizer. In order to profitably use accumulated dust, it is used to fertilize plants in the summer.
To prevent the dust from exploding, it is pre-wetted - for example, moisture is sprayed through a spray bottle. After moistening, the dust is collected and dissolved in water. It is very important to wet not only the top layer of dust, but the entire layer.
Is Azofoska flammable? This agrochemical does not ignite, however, when heated to high temperatures it can release a toxic substance. Therefore, be careful when storing fertilizer.
How is the agrochemical stored? It is kept in tightly sealed plastic bags. This storage method ensures the preservation of active substances for up to 1.5 years. In the placer state, Azofoska loses its qualities within six months.
Bottom line
Azofoska is the main fertilizer for growing potatoes. It is also used to feed any fruit and vegetable crops and plants - flowers, bushes, fruit trees and shrubs. The beneficial effect of fertilizer on the formation of the root system and photosynthesis allows it to be used for feeding home flowers.
The storage conditions of the drug should be observed and overdose should not be allowed during use. Remember that exceeding the application rate of fertilizers does not increase the yield, but accumulates in the fruits.
Azofoska is not toxic, however, at high temperatures it releases a dangerous substance. Do I need to protect myself when using an agrochemical? This should not be done - the drug is completely safe for health.

Today, one of the most used and popular fertilizers in agriculture is the drug “Azofoska”. This balanced mineral fertilizer has long been used in large-scale industrial farming, and it is also quite applicable in small gardens and summer cottages.
“Azofoska” - what is it?
Fertilizer "Azofoska"It is produced in granular form, it is a complex fertilizer with a wide range of applications, it belongs to nitroammophosphates.
This is a neutral agrochemical used on all types of soils, for all cultivated and ornamental plants. The maximum effect is noticeable on poor soils: sandy or clayey, less on chernozem, since the soil itself is nutritious.
There are several brands of Azofoska, so the composition of the fertilizer and the percentage of elements may be different.
The main active element is nitrogen, it is a component of plant cell protein and participates in all its life cycles. The percentage of substance depending on the brand is from 16% to 26%.
Potassium amount ranges from 5% to 18%, the element is necessary for plants for good metabolism, it helps to form the root system, is responsible for the taste and color of future fruits, actively participating in their formation. A lack of potassium can reduce plant immunity to diseases and their resistance to changing weather conditions.
"Azofoska" contains sulfur in small quantities- from 2.6% to 4%, but this amount is quite enough for normal photosynthesis, in which the element takes part, for the breakdown of non-protein compounds (nitrates) formed with excess nitrogen, for the formation of useful acids, essential oils and other organic compounds in fruit and grain crops. 
Did you know? Many people, when they hear the word nitrate, imagine something terrible and harmful, but in defense of these substances it is worth saying that in small quantities they are beneficial for plants. These are salt components that help the plant absorb nitrogen, which is necessary for the formation of chlorophyll.
When is Azofoska fertilizer used?
When it is necessary to fertilize with Azofoska, each crop has its own methods and timing. Fertilizer is applied when digging in the fall as the main fertilizer; when planting in a hole; in the spring into the soil before planting procedures, after harvesting.
It is better to fertilize heavy soils after harvesting the predecessor. Light - in the spring, since melt water can wash out the autumn application of "Azofoska".
"Azofoska" - universal fertilizer: its methods and areas of application are quite diverse. The drug is used for both root and foliar feeding, in liquid solution and in dry form. "Azofoska" is used:
- when sowing seeds, to fertilize seedlings during germination;
- when growing tuberous, root and bulbous crops;
- “Azofoska” is well suited for many garden crops: for grapes and strawberries, for fruit trees and shrubs;
- The drug is used on lawns and for ornamental flowers and shrubs.
Features of using "Azofoska": how to properly fertilize plants
“Azofoska” is a mineral fertilizer; its overdose can be fraught, so before applying the fertilizer, carefully read the instructions. All useful substances are absorbed in small quantities by the root system of plants, while the excess accumulates in the fruits, entering our body.
Important! One of the rules for using mineral fertilizers: in the third year after using mineral preparations, the soil needs rest. To prevent nitrates from accumulating in it, alternate with organic matter.
When fertilizing in the spring, “Azofoska” should not be applied to soil that has not yet been warmed up; cold soil, especially the top layer, can accumulate nitrates. Therefore, the best time for application is in spring in May, in autumn in September, and maximum in the first ten days of October.
Let's figure out the dosage of fertilizer: how to apply it in dry form and how to dilute Azofoska in water.
For all annual crops when spreading per square meter, take from 30 to 45 g of the composition.
Under bushes and trees There are 35 g of granules per square meter of tree trunk circle.
For root dressings prepare a solution in proportions of 2 g per liter of water; prepare a solution for home flowerpots in the same proportion.
When feeding “Azofoskaya”, planting seedlings in open ground tomatoes, peppers and eggplants into the hole, add half a teaspoon of granules. 
Interesting fact! Nitrates are used not only in the agricultural industry; some compounds of these chemicals are used as components of rocket fuel, and are also used by pyrotechnicians in the manufacture of explosive compounds.
Advantages of using Azofoska for garden crops
As already mentioned, “Azofoska” is suitable for all types of soil and all garden plants. The drug has good contact with seeds and seedlings, which is its undoubted advantage over other drugs. Let's look at the example of the two most popular garden crops - tomatoes and potatoes.
Fertilizer "Azofoska" when used for potatoes satisfies all the crop's needs for nutrients and nutrients. The seedlings of the crop gain resistance from sudden temperature changes, drought or heavy rainfall. Fertilizer increases immunity to diseases, increases the quality and quantity of the crop, as well as the ability of tubers to be stored for long periods of time, preventing possible potato rotting.
Fertilizer "Azofoska" when used for tomatoes hardens seedlings after planting in open ground, increases the ability to resist pathogenic bacteria and adverse weather conditions. Thanks to its balanced composition, it saturates the crop as much as possible, without the risk of oversaturation with individual elements. This is an ideal fertilizer for tomatoes at the beginning of their active growth and development. 
So, the main advantages of the Azofoska mineral fertilizer:
- the main source of properly balanced mineral elements;
- dissolves in water without sediment and is well absorbed by plants;
- stimulates growth and rooting, strengthens the root system;
- increases disease resistance, increases yield;
- It is practically not washed out by precipitation, saturating the soil for a long period.
Rules for storing Azofoska fertilizer
“Azofoska” is not a dangerous fertilizer, however, the instructions for use describe the conditions for proper storage. The rules must be followed, as there are some nuances.
First– dust from the drug tends to spontaneously explode when there is a large accumulation and dryness. In this case, the dust is sprayed with water, then collected and used, diluted with water.
Second nuance– fertilizer, when heated to 200 degrees, releases toxins that are hazardous to health.
After using “Azofoska” in a dacha or garden plot, the drug must be stored in tightly closed bags: either this is a form with a plastic retainer, or the edge of the bag must be sealed.

Agriculture
Soddy-podzolic soil
. The application of azophosphate ensures maximum efficiency in forest-meadow and forest-steppe zones, in crops of sugar beets, grains, potatoes, and flax. A high positive effect is observed when applied in spring compared to autumn application. On winter crops, the dose of fertilizer is divided in half between autumn and spring application.In areas of sufficient moisture, especially on light soils, it is recommended to use complex fertilizers with a lower nitrogen content (1: 2: 2, 1: 2: 1, 1: 4: 0) in the fall, followed by the addition of additional nitrogen to the optimal content in the spring .
Application on various types of soils
Chernozems, leached and soddy-podzolic clay soils
. A one-time application of the entire dose of fertilizer is equal in effectiveness to fractional application.Ordinary chernozems, carbonate, southern
. The effectiveness of azofoska is lower than in the more humid forest-meadow zone.Chestnut soils and gray soils
. With irrigation, the effectiveness of azofoska increases significantly, especially for grain crops, cotton and corn.Impact on crops
When azofoska is introduced into the soil, due to the uniform distribution of nutrients and increasing their positional availability, the yield of all agricultural crops increases. The presence of several ions leads to their combined effect on the plant, in which the combined effect significantly exceeds the effect of each ion separately (synergism) and contributes to better use of nutrients by plants.
Cereals, corn, cotton
- the effectiveness of azofoska is higher than mixtures of simple fertilizers, especially on chestnut soils and gray soils under irrigated farming conditions.Industrial, silage crops and annual grasses
respond well to all methods of applying azofoska. (Compiled)Receipt
The raw materials for producing azophosphate are extraction or thermal phosphoric acid, weak nitric acid and potassium salts. Technological schemes differ in the methods of neutralization of phosphoric and nitric acids.
Nitroammophoska grade 17:17:17 is obtained as a result of the introduction of potassium chloride as a potassium component. When introducing potassium sulfate, the grade 16:16:16 is obtained.
With the onset of each season, all gardeners and gardeners have high hopes for the future harvest. I want all the efforts and time spent to pay off handsomely. But it is not enough to choose high-quality planting material and plant it correctly. Plants need not only care, but also feeding, which ensures their full growth and development. And in this regard, it is difficult to overestimate the role of various fertilizers. You can increase the productivity of garden and garden crops with the help of mineral fertilizers. If you feed the plants in a timely manner and in an appropriate amount, this will have a positive effect on both the quality and quantity of the harvest.
Among the currently existing mineral preparations, the use of preparations containing such important minerals as nitrogen, potassium and phosphorus is quite common. This is due to their high efficiency and availability. Private farmers have long been convinced that the use of a fertilizer such as azofoska allows them to obtain large yields at minimal cost.
The principle of action of the drug
The composition of azofoska includes nitrogen, potassium and phosphorus in the ratio 22:11:11 or 1:1:1, as well as sulfur in a small amount. The main purpose of this fertilizer is to meet the mineral nutrition needs of garden and vegetable crops. Azophoska is used as an additional or main application in order to activate growth processes, strengthen the root system and increase the resistance of crops to adverse factors (drought, frost). In addition, the use of azofoska in the country or on agricultural land allows you to prolong the flowering of plants, protect them from diseases, increase the nutritional value of fruits and, of course, increase productivity. If the norms for applying azofoska are observed, the shelf life of the crop also increases, because the quality of the fruit improves.
This preparation is characterized by good retention in the soil; precipitation does not wash it out. Azophoska is produced in the form of small yellow-beige or white granules. They are non-hygroscopic, as they are treated with surfactants that prevent caking.
Rules for using the drugAzofoska (or nitroammofoska) is a universal product, ideal for all types of garden and vegetable crops. The use of azofoska is even justified. Most often, this mineral complex is used when growing shrubs, fruit and berry trees, bulbous and tuberous plants. The application of azophosphate improves the germination of seeds and activates the growth of seedlings.
As for the soil, this mineral preparation can be applied to open and protected soil of any type. It is advisable to enrich clayey, peat-bog, sandy and even chernozem soils with nitrogen, potassium and phosphorus. If the soil on your site is heavy and dense, then after harvesting it is recommended to apply azofoska as the main fertilizing. Light soil should be fertilized in the spring, during the first plowing.
The timing of application and the rate of application of azofoska are determined depending on the type of soil on your site and what crop you plan to grow. On average per square meter 
It is recommended to use about 35-40 grams of azofoska for soil. If you are planting potatoes, it is recommended to add 3-4 grams of the drug to each hole. Berry bushes and fruit trees will bear fruit better when 25-30 grams of azofoska are added per square meter of soil. And watering balcony and indoor flowers should be done twice a month with a solution of this drug (up to 20 grams of azofoska per bucket of water).
This drug is effective and economical. A kilogram package costs about 20 rubles. In addition, you will not need to additionally purchase other complex fertilizers, which is very profitable.
All owners of vegetable gardens, summer cottages and personal plots know very well that it is simply impossible to get a good harvest in modern conditions without the use of various mineral fertilizers.
The most popular is the three-component fertilizer azofoska. The instructions for use are simple and clear, so the use of this drug does not cause difficulties for novice gardeners.
Characteristics and functions of fertilizer
Of course, you can use organic fertilizers, but they do not allow you to take into account all the characteristics of the soil, the time of fertilizing, the growing season and the type of crop. For this reason, complex mineral fertilizers are in great demand among modern gardeners.
Azofoska is a complex mineral fertilizer consisting of components that are very important for the rapid and proper development of plants. We are talking about nitrogen, phosphorus and potassium. The concentration of useful substances in the preparation reaches 50% percent of the total mass of the product. Depending on the types of complex nutrition contained in it nitrogen, phosphorus and potassium may have different proportions.
Another important component of fertilizer is sulfur.
This substance is present in the mineral complex in small quantities, but it is sufficient to normalize the processes of photosynthesis and neutralize nitrates, which can be formed with excess nitrogen.
Also, with the participation of sulfur, useful acids, essential oils and other important organic compounds are formed in plants.
Azofoska has the following characteristics:
- The color of the granules of the mineral complex is light pink, less often white.
- The sizes of azofosk fertilizer granules range from 1 to 5 mm.
- The fertilizer does not cake during long-term storage.
- It dissolves easily and is perfectly absorbed by plants.
- The drug is considered non-toxic. It does not burn and does not absorb moisture from the air.
- If you store azofosk fertilizer outdoors without packaging with free access to sunlight, it will quickly lose all its beneficial properties.
Thanks to its complex composition, azofoska has the following effects on: plants:
- Increases the nutritional value of the final product.
- By increasing the fat content of the fruit, the total weight of the harvest increases.
- Increases the shelf life of crops.
- Allows you to avoid the development of various diseases and facilitates the adaptation of plants to unfavorable climatic conditions.
Is azofoska dangerous?
Many people are afraid of nitrates, which accumulate in plants due to excess nitrogen. That is why the manufacturers of the drug try not to mention the second name of this mineral complex - nitroammophoska. They can be understood: against the backdrop of talk about the dangers of nitrates, azofoska may develop a negative reputation.
Word nitro in the name nitroammofosk, indicates that the main active substances of the fertilizer are included in it in nitrate form. It is she who provides excellent level absorption of nitrogen, phosphates and potassium by the plant. Due to its nitrate form, the drug has an equally good effect on all garden plants.
To completely protect yourself from the danger of nitrate accumulation, you should adhere to certain rules use of azofoska. They are described in detail in the instructions for use:
- The drug should be administered strictly according to the norm. If it is exceeded, the nitrates will not be completely absorbed and will settle in the tissues of the plant and its fruits.
- Azofosk fertilizer must be applied in a certain order. We are talking about alternating mineral and organic fertilizers. With constant use of the drug without alternating with organic matter, there is a risk of accumulation of nitrates in the soil.
- Under no circumstances should azofosk fertilizer be applied to insufficiently warmed soil. A lack of thermal energy can cause the accumulation of nitrates in the upper layers of the soil. From there they will certainly get into the plants. For this reason, application of fertilizer later than the first week of September is not allowed. In spring, mineral fertilizing can be applied to the soil only at the very end of May.
By the way, using manure as an organic fertilizer, a gardener also runs the risk of contaminating the soil with nitrate compounds. For this reason, it is recommended to replace manure with compost.
Each crop has its own methods and timing of fertilization, but there are also general rules.
If the site has heavy soil, it should be fertilized after harvesting. On light soils, it is recommended to use azofoska 2 times a year. The fact is that fertilizer applied to the soil in the fall can be washed away with water until spring.
Since azofoska is a universal fertilizer, it can be used to solve a wide variety of problems. tasks:
- Immediately at the time of sowing the seeds.
- When germinating seedlings.
- For growing root crops, tubers and bulbs.
- When growing grapes, apples and various berries.
- Azofoska can also be used for growing lawn grass, flowers and various ornamental shrubs.
Varieties of azofoska
The use of this fertilizer largely depends on what type of mineral complex is used. Depending on the quantitative ratio of active substances in the composition, they are distinguished three varieties azofoski:
Please note that, according to the instructions for use, azofoska can be used on any soils, regardless of the type of preparation. However, it will give the best results if it is used taking into account the condition of the soil and the type of plants being grown.
Storage of azofoska
Overall this fertilizer is perfect safely for humans, since it contains no harmful substances. But if stored incorrectly, azofoska can become dangerous. Here are some recommendations for use that are not in the official instructions:
- Large accumulations of dust from this fertilizer may spontaneously explode. Therefore, when storing the drug, it is recommended to regularly collect and dispose of this dust.
- You should also remember that when heated too much, azofoska may begin to emit gases that can be harmful to humans.
- To avoid all the troubles described above, it is recommended to store azofoska in tightly sealed plastic bags.
- If you store fertilizer in bulk, then even in a closed room without access to light, it will lose its beneficial properties within six months.
