Minerals are necessary for plants to actively grow and bear fruit. Complex fertilizers that include elements vital for plants are considered especially effective. One of them is nitroammophoska, suitable for feeding all types of crops.
Fertilizer composition
Nitroammophoska contains three main components: nitrogen (N), phosphorus (P) and potassium (K). The NPK complex directly affects the growth and fruiting of garden crops.
The fertilizer consists of small granules of a gray-pink flower, highly soluble in water. The shade varies depending on the batch and manufacturer.
Nitrogen contributes to the formation of green mass in plants, the passage of photosynthesis and metabolism. With a lack of nitrogen, crop growth slows down, which affects their appearance. As a result, the growing season is shortened and yields are reduced.
During the development period, plantings need phosphorus. The trace element is involved in cell division and growth of the root system. With a lack of phosphorus, the color and shape of the leaves change, and the roots die.
Potassium affects the yield, taste of fruits and plant immunity. Its deficiency reduces plant resistance to diseases and pests.This feeding is especially important during the period of active growth. Potassium is applied in the fall to increase the winter hardiness of shrubs and trees.
Nitroammophoska contains forms that are easily absorbed by plants. Phosphorus is available in three compounds, they begin to act actively after use. The main compound is monocalcium phosphate, which dissolves in water and does not accumulate in the soil.
Advantages and disadvantages
Nitroammofoska is an effective fertilizer that is beneficial when used correctly. When using a substance, you need to consider its pros and cons.
Advantages of nitroammophoska:
- high concentration of useful minerals;
- the presence of a complex of substances necessary for the development of crops;
- good solubility in water;
- storage at home;
- preservation of structure and color within the shelf life.
- increase in yield up to 70%;
- variety of uses;
- affordable price.
Main disadvantages:
- is of artificial origin;
- short shelf life (no more than 6 months from the date of manufacture);
- long-term use leads to the accumulation of nitrates in the soil and plants;
- the need to comply with storage rules due to flammability and explosion hazard.
Varieties and analogues
Depending on the concentration of active ingredients, several types of nitroammophoska are distinguished. They are used on different types of soil.
The most common fertilizer is 16:16:16. The content of each of the main components is 16%, the total amount of useful substances is more than 50%.The fertilizer is universal and suitable for any soil. Sometimes the designation 1:1:1 is used, which indicates an equal ratio of the main substances.
On soils deficient in phosphorus and potassium, the composition 8:24:24 is used. Their final content reaches 40% or more. Fertilizing is effective for root crops, winter crops, potatoes, suitable for regions with frequent rainfall. It is applied to the soil after harvesting grains and legumes.
If the soils are rich in phosphorus, then use nitroammophoska in the composition 21:0.1:21 or 17:0.1:28. On other types of soil, it is used before planting rapeseed, fodder crops, sugar beets, and sunflowers.
Manufacturers produce nitroammophoska, the composition of which takes into account the characteristics of a particular region. In the Voronezh region, fertilizers 15:15:20 and 13:13:24 are sold. The local soil contains little potassium, and such fertilizing ensures high yields.
Nitroammofosk has analogues that are similar in composition:
- Azofoska. In addition to the main three elements, it contains sulfur. Has a similar effect on plants.
- Ammofoska. The fertilizer is enriched with sulfur and magnesium. Suitable for processing crops in closed ground.
- Nitrophoska. In addition to the main complex, it includes magnesium. Contains forms of nitrogen that are quickly washed out of the soil.
- Nitroammophos. Does not contain potassium, which limits its scope of application.
How to use
Application fertilizers nitroammofosk perhaps before planting crops or during their growing season. The best results are obtained on chernozem soils with high moisture levels.
If the soil has a dense structure, the penetration of nutrients occurs more slowly.It is better to fertilize chernozem and heavy clay soil in the fall. Fertilizer is applied to light soil in the spring.
Plants are processed at any stage. The last fertilizing is carried out 3 weeks before harvesting. Application rates depend on the type of crop.
Tomatoes
After treatment with nitroammophoska, the immunity of tomatoes is strengthened, their growth and fruiting are accelerated. The fertilizer is combined with other substances containing potassium and phosphorus: superphosphate, potassium sulfate.
The order of tomato subcortex includes several stages:
- 2 weeks after transplanting into a greenhouse or open area;
- one month after the first treatment;
- during the formation of ovaries.
For the first feeding, prepare a solution consisting of 1 tbsp. l. substances into a large bucket of water. 0.5 liters are poured under the bush.
The following treatment is prepared in combination with organic matter. A 10-liter bucket of water requires a tablespoon of fertilizer and 0.5 kg of bird droppings.
For the third feeding, add 1 tbsp to the nitroammophoska. l. sodium humate. The resulting product is applied to the roots of plants.
cucumbers
The use of nitroammofosk fertilizer for cucumbers increases the number of ovaries and the duration of fruiting. Feeding cucumbers includes two stages:
- application to the soil before planting the crop;
- watering until the ovaries appear.
For 1 sq. m of soil requires 30 g of the substance. To form ovaries, water the cucumbers with a solution consisting of 1 tbsp. l. fertilizers per 5 liters of water. The amount of product for each bush is 0.5 liters.
Potato
Nitroammofoska is used when planting potatoes. Place 1 tsp in each well. substance that is mixed with soil. Fertilizing accelerates the formation and growth of roots.
The planted potatoes are watered with the solution. For 20 liters of water add 2 tbsp. l. substances.
Peppers and eggplants
Nightshade crops are fed in the spring. 3 weeks after planting in the ground, prepare a nutrient solution consisting of 40 g of fertilizer per large bucket of water.
Fertilizing stimulates fruiting of peppers and eggplants, improves the taste and quality of the fruit. Treatment is carried out in the morning or evening.
Berry and fruit crops
Nitroammofoska is used for root feeding of fruit-bearing shrubs and trees. Standards of use are determined as follows:
- 400 g for apple, pear, plum and other fruit trees;
- 50 g for raspberries;
- 70 g for gooseberry and currant bushes;
- 30 g for strawberries.
The substance is embedded in the planting hole. During the season, shrubs and trees are sprayed with a solution. Add 10 g of nitroammophoska to 10 liters of water.
The vineyard is also treated with a nutrient solution leaf by leaf. The concentration of the substance is 2 tbsp. l. for a large bucket of water.
Flowers and indoor plants
In spring, the flower garden is fed a couple of weeks after the sprouts appear. The fertilizer is suitable for annual plants and perennials. For 10 liters of water, 30 g is enough.
When buds form, a more concentrated solution is prepared, including 50 g of fertilizer. Additional processing is carried out during the flowering period.
Feeding for garden roses is especially effective. It is better to feed roses in spring and autumn, and during the season it is enough to spray the solution.
Indoor plants are sprayed with a solution consisting of 20 g of fertilizer per 5 liters of water. Treatment promotes flowering.
Precautionary measures
Nitroammophoska belongs to safety class 3. If the rules of use and storage are violated, the substance causes harm to humans, plants and the environment.
Rules for using nitroammophoska:
- Do not allow the fertilizer to overheat. Store it in a room with a temperature below +30°C. Do not leave the substance near a heater, stove or other heat sources.
