Ammophoska - granulated mineral fertilizer. It does not cake, contains useful chemical elements and a minimum of ballast additives. Let us consider in more detail its features, as well as instructions for use.
The composition and purpose of ammofoski
Ammophoska contains elements necessary for plants. The basic composition is as follows:
- Nitrogen, 12%.
- Phosphorus, 15%.
- Potassium, 14%.
- Sulfur, 14%
Nitrogen increases the yield of plants, is a building material for cells, promotes the synthesis of elements. Contained in quantities not causing the accumulation of nitrates in plants.
Phosphorus responsible for the operation of the energy source ATP and nucleotides that regulate the energy metabolism of the plant.
Potassium sulfate increases yields, improves fruit quality, increases resistance to adverse growing conditions.
Sulfur helps the plant absorb nitrogen, fully assimilate it and does not acidify the soil.Ammofoska fertilizer in granules close up
The mechanism of action of fertilizer
Decorative flowers and shrubs, lawn grass fertilized in the spring. Under its influence, plants get a good development, bright flowers and juicy fruits. At processing of potato plantations, the size of tubers increases, tastes, their safety are improved.
Ammophos allows you to get a high yield of tomatoes. Potassium contributes to the rapid formation of ovaries and the growth of fruits. Tomato bushes become resistant to stressful situations and pests. For cabbage and various greens, 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 food for a long period. Its chemical substances break down into separate ions, this improves their absorption by the roots of the plant.
Advantages and disadvantages
Let us dwell on the advantages:
- The composition is allowed to make at any time of year, except for winter. Already in early March, the ammonium can be scattered over the snow.
- Non toxic, excess nitrogen is not absorbed and does not increase the content of nitrates in the finished fruit.
- The balanced maintenance of elements promotes their full effective absorption and assimilation.
- Easily soluble in water can be used both in granules and in the dissolved state.
- This complex can be used as a top dressing during growth and as the main fertilizer during planting.
The disadvantages include the following:
- Chemical powder of the 4th class of danger, it is necessary to observe precautions when working with it.
- At non-observance of a dosage acidity of the soil after its use increases.
Instructions for preparation and use
The amount of drug used depends on the crop, the soil on which the plant grows and the time of application.
Determination of the dose for feeding
When making the complex in the fall lay the minimum dose.
When planting onions, scatter the powder at the rate of 15 g / m2. 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 the wells, while laying in 2 g of the mixture in each. You can scatter fertilizer in the amount of 25 g / m2 on the surface and level the soil.
Fertilizing trees, make 50 g under each tree, the same dose is suitable for fruit bushes. For old plantations add 100 g under the plant. Feeding up flowers and ornamental shrubs, apply 10 g / m2 of granules, if the soil is fertilized regularly, otherwise increase the dose to 20 g.
Ammophos has a good effect on the growth and quality of the grassy lawn. Spray 15-25 g / m2 of powder on a wet herbal surface. In dry weather, it should be watered, keeping it moist for some time.
Useful fertilizer for soil in the greenhouse. Scatter the mixture on the surface of the soil, close up with a rake. When planting seedlings, add 1 tsp. powder in the landing hole, mixing with the ground. In the future, feed the culture with a solution of 3 tbsp. spoons of powder for 10 liters of water. Pour 1 liter of fluid under the bush during periods of flowering and ripening fruits.
Terms and methods of entering into the soil
The first term of making ammofoski can be considered autumn. It is brought under the autumn digging of the soil and under the bushes and trees, followed by incorporation into the ground.
The next processing time is spring. You can make in March on the melting snow, scattering on the surface. Melting snow dissolves fertilizer and sucks it into the soil.
Next, the complex mixture is applied when feeding the plants at least three times per season. From August, feeding is stopped, because nitrogen promotes the growth of green mass of the plant, which is harmful by autumn. At this time, the plant should promote the ripening of fruits, not leaves. Young shoots of bushes and trees are also superfluous, in winter they will die undigested.
Security measures when working with the drug
The drug belongs to the 4th class of hazardous substances, it is not flammable and is not explosive. Precautions when working such:
- Work must be carried out in protective clothing and gloves.
- Be sure to protect the respiratory organs with a respirator or mask.
- Avoid contact with open skin and inside.
- After work, wash your face and hands with soapy water.
Terms and conditions of storage
Like any chemical drug ammofoska requires caution during storage. Do not store open packages with it. It is better to pour the remains in tightly closed capacity, only not metal. The room should not be wet. Storage temperature is valid from 0 to 30 degrees. Access for children and animals is limited. Store no more than 9 months.
Ammophoska - fertilizer with a high concentration of nutrients, well balanced. This makes it convenient to use, allows you to be content with low doses of application. An important factor in choosing this composition is its reasonable price, which allows you to reasonably save.
