Ammofoska is a granular mineral fertilizer. It does not cake, contains useful chemical elements and a minimum of ballast additives. Let's consider in more detail its features, as well as instructions for use.
The composition and purpose of ammophoska
Ammophoska contains the elements necessary for plants. The main composition is as follows:
- Nitrogen, 12%.
- Phosphorus, 15%.
- Potassium, 14%.
- Sulfur, 14%
- Magnesium.
Nitrogen increases the productivity of plants, is a building material for cells, promotes the synthesis of elements. Contained in an amount that does not cause the accumulation of nitrates in plants.
Phosphorus is responsible for the work of the energy source ATP and nucleotides, which regulate the energy metabolism of the plant.
Potassium sulfate increases yield, improves fruit quality, increases resistance to unfavorable growing conditions.
Sulfur helps the plant to absorb nitrogen, completely assimilate it and not acidify the soil.
Fertilizer mechanism of action
Ornamental flowers and shrubs, lawn grass are fertilized in spring. Under its influence, plants get good development, bright flowers and juicy fruits. When processing potato plantations, the size of the tubers increases, the taste and their preservation improve.
Ammophos allows you to get a high yield of tomatoes. Potassium promotes the rapid formation of ovaries and fruit growth. Tomato bushes become resistant to stressful situations and pests. For cabbage and various vegetable garden herbs, this composition helps to increase the volume of green mass, making it more juicy.
Ammophoska granules dissolve slowly in moist soil, which provides plants with nutrition for a long period. Its constituent chemicals break down into individual ions, which improves their absorption by the plant roots.
Ammofoska, a fertilizer that admits proximity to almost all fertilizers used. The only exception is phosphate slags.
Advantages and disadvantages
Let's dwell on the advantages:
- The composition is allowed to be applied at any time of the year, except for winter. Already at the beginning of March, ammophoska can be scattered over the snow.
- Non toxic, excess nitrogen is not absorbed and does not increase the content of nitrates in finished fruits.
- The balanced content of the elements contributes to their complete effective absorption and assimilation.
- Easily soluble in water can be used both in granules and in dissolved state.
- This complex can be used as a top dressing during growth and as the main fertilizer for planting.
The disadvantages include the following:
- Chemical powder of the 4th hazard class, it is necessary to observe precautions when working with it.
- If the dosage is not observed, the acidity of the soil increases after its application.
Instructions for preparation and use
The amount of the preparation used depends on the crop, the soil on which the plant grows and the time of application.
Determination of the dose for feeding
When introducing the complex in the fall, lay the minimum dose.
Enough 20 g per square meter. In the spring, when loosening the soil, add the missing amount.
When planting onions, scatter 15 g / m2 powder over the garden bed. For root crops (carrots, beets), add granules to the planting furrows, 10 g per meter of furrow. In small areas, it is convenient to plant potatoes in holes, while putting 2 g of the mixture in each. You can spread fertilizer in an amount of 25 g / m2 over the surface and level the soil.
When fertilizing trees, 50 g is applied under each tree, the same dose is suitable for fruit bushes. For older plantings, add 100 g per plant. When feeding flowers and ornamental shrubs, add 10 g / m2 of granules if the soil is regularly fertilized, otherwise increase the dose to 20 g.
Ammophoska has a good effect on the growth and quality of the grassy lawn. Spread 15-25 g / m2 of powder onto damp grass. In dry weather, water it, keeping it moist for a while.
Fertilizing the soil in the greenhouse will be helpful. We scatter the mixture over the soil surface, close it up with a rake. When planting seedlings, add 1 tsp. powder into the landing hole, mixing with the ground. In the future, feed the cultures with a solution of 3 tbsp. tablespoons of powder per 10 liters of water. Pour 1 liter of liquid under the bush during flowering and ripening periods.
The fertilizer dissolves well in water. For the solution, warm water is used, since nitrogen evaporates in hot water, and phosphorus does not dissolve in cold water. Wait until the granules are completely dissolved, strain the small precipitate.
Terms and methods of application to the soil
Autumn can be considered the first time for adding ammophoska... It is introduced under the autumn digging of the soil and under the bushes and trees, followed by embedding in the ground.
The next processing time is spring. Can be applied in March over melting snow, scattering over the surface. The melting snow dissolves the fertilizer and draws it into the soil.
Further, the complex mixture is applied when feeding plants at least three times per season. Since August, feeding is stopped, since nitrogen contributes to the growth of the green mass of the plant, which is harmful by autumn. At this time, the plant should help ripen the fruit, not the leaves. Young shoots of bushes and trees are also superfluous, in winter they will die unripe.
Safety measures when working with the drug
The drug belongs to the 4th class of hazardous substances, it is not flammable and not explosive. Precautions during work are as follows:
- Work must be carried out in protective clothing and gloves.
- Be sure to protect the respiratory system with a respirator or mask.
- Avoid contact with open skin and inside.
- After work, wash your face and hands with soapy water.
In case of contact with eyes, rinse immediately with clean water. If you accidentally swallow a solution or powder, induce vomiting and flush your stomach. After that, contact a medical institution for help.
Storage conditions and periods
As with any chemical preparation, ammofosk requires careful storage. You should not store open packages with it. It is better to pour the leftovers into a tightly closing container, but not a metal one. The room should not be humid. Storage temperature is permissible from 0 to 30 degrees. Access for children and animals is limited. Store no more than 9 months.
Ammofoska is a fertilizer with a high concentration of nutrients, well balanced. This makes it convenient for use, allows you to be content with low application rates. An important factor in choosing this composition is its affordable price, which allows reasonable savings.
