Looking for good fertilizer for potatoes, then take the advice of experienced agronomists - choose Azofoska. The drug is widely used in agricultural enterprises; for summer residents, domestic chemical enterprises produce the drug in convenient small-volume packages. Fertilizer is applied to any vegetable and fruit crops and used in floriculture.
Compound
Azofoska is granules with a diameter of 1 to 5 mm, white or gray. The granules do not absorb moisture, so they remain crumbly even after long-term storage. The drug is easy to dissolve in water; aqueous solutions of azofoska are quickly absorbed by plants.You can sell packages of Nitroammofoska fertilizer, this is the same azofoska, the only difference is in the name.
Azofoska contains microelements necessary for any plant:
- N—nitrogen;
- P—phosphorus;
- K - potassium.
On different types of soils, the plants' need for these elements is different, so several brands of azofoska have been produced, the most popular of which are:
- NPK 16:16:16;
- NPK 19:9:19;
- NPK 22:11:11.
The first brand contains microelements in equal proportions; it is recommended to apply it to the soils of the middle zone. This farming zone is characterized by low phosphorus content in the fertile layer.
The second type of fertilizer is suitable for southern regions with arid climates. The soils there are usually rich in phosphorus. The third grade is applied to soil depleted by annual exploitation. The drug contains sulfur in small quantities (2.6–4%), which is needed by plants for photosynthesis.
About the benefits of use
Azofoska is an ideal fertilizer for potatoes. When using Azofoska fertilizer, a convincing increase in yield is obtained. The benefits of using it are as follows:
- potato bushes receive a full range of nutrients;
- plants adapt better to sudden changes in weather;
- potatoes get sick less often;
- tubers retain their consumer qualities longer during storage.
Nitroammophos can be fed to tomato seedlings after transplanting them into the ground. Young tomatoes take root faster and get sick less often. The fertilizer can be applied to soils of any type (chernozems, wetlands, loams), this is its undoubted advantage over other preparations.
Practice has shown that the results of application are more noticeable on heavy soils, in which it is difficult to ensure the same concentration of nutrients over the entire planting area. The cost of the product is also one of its advantages; it is quite affordable. On average per 1 sq. m. consume 40 g of Azofoski. Due to its low cost, the product can be used profitably even on large planting areas.
Let's evaluate what the elements N, P, K are needed for:
- N - promotes protein synthesis, which affects growth and duration of life cycles;
- P - plants need for development throughout the growing season;
- K - affects the taste of fruits, the quality of roots and local immunity.
Sulfur is contained in azophoska in minimal quantities, but it is quite sufficient for normal photosynthesis. Sulfur protects our health; it neutralizes nitrates formed due to excess nitrogen content.
Tips for proper use
Any fertilizer will not cause harm if it is used wisely, without violating the recommendations specified in the instructions for the drug. This also applies to Azofoski. The vegetables in your garden will not contain harmful impurities if you adhere to the rules given below:
- Apply fertilizer to each crop without exceeding the norm; excess fertilizer in nitrate form will accumulate in the fruits.
- To prevent the accumulation of nitrate compounds in the soil, use not only mineral fertilizers, alternate them with organic matter, the most useful are light forms: liquid green fertilizers, compost.
- Do not apply Azofoska to unheated soil. With a lack of heat, nitrates will accumulate in the top layer of soil. In the fall, apply Azofoska in early September, before the soil has cooled.In spring, not earlier than the end of May. At this time, the earth has already warmed up, but still retains moisture obtained from melting snow.
Proper storage
Azofoska is included in the group of drugs of class III hazard. It has specific features that should be taken into account when storing large volumes of fertilizer:
- a large volume of dust from Azofoska accumulated in the storage facility can explode if the air is very dry;
- When heated to 200 °C, toxic substances harmful to health are released.
The listed risks are typical for storing fertilizer on a large scale. In dacha conditions, fertilizer is used in small volumes; storing it is easy and harmless. When storing, adhere to the following rules:
- after use, seal the fertilizer bag tightly with a paper clip;
- store in a dry, dark place with good ventilation;
- Storage duration is up to 1.5 years.
After the expiration date, the fertilizer should not be used; it is better to dispose of it properly.
Instructions for use
The benefits of Azofoska are observed when applied to any vegetable, flower and fruit crops. The fertilizer has no restrictions on the age of plants; it is applied to seedlings and adult plants. Application rates for different crops are shown in the table.
| Culture | area (place) of application | weight (g) |
| annual vegetable crop | 1 ha | 45 |
| potato | hole | 4 |
| mature bush, tree | the entire area of the tree trunk circle | 35 |
| liquid fertilizer for summer root feeding | water 1 l | 2 |
Deadlines
On heavy soils, Azofoska should be applied in the fall after harvesting and clearing the beds of plant debris. In sandy and sandy loam soils, fertilizer can be lost during winter and spring along with melt water, so it is applied twice: in autumn and spring.In the spring, Azofoska is added to the ground immediately before planting (seeds, seedlings, seedlings).
About danger
For some summer residents, the fear of nitrates has developed into a real phobia. The second name of Azofoska - nitroammofoska terrifies them. Few people know that “nitro-” in this case refers to the nitrate form of the active elements (N, P, K). This form of nutrients is the easiest for plants to absorb.
It should be noted that organic matter (manure, humus, compost) when applied in excess to the soil also pollutes it with harmful nitrate compounds. It is much easier to adhere to application rates with granular fertilizers than with manure.
Conclusion
Do not be afraid to use modern mineral fertilizers in gardens and vegetable gardens. When properly applied to the soil, Azofoska will benefit the crop. Azofoska is the best fertilizer for a valuable vegetable crop in our country - potatoes.
