Diammofoska - fertilizer composition and use in the garden, video

To obtain a good harvest, regular application of not one or two, but a whole complex of fertilizers and protective preparations is required. This will help you fully grow and develop, be filled with vital energy, and acquire a marketable appearance.

Fertilizers are required not only for vegetable crops, but also for shrubs, trees, and flowers. A fertilizer such as Diammofoska provides comfort for plants and peace of mind for the farmer. The constituent elements of the drug combine perfectly.

The drug has the necessary qualities. Feeding is convenient and because it is suitable for all crops, it can be used throughout the season. Since it is allowed to apply Diammofoska before planting, as an additional means of fertilizing.

Composition and characteristics of the fertilizer

The components of Diammofoska include elements vital for the plant: nitrogen (A), potassium (K), phosphorus (P). The advantage remains with potassium and phosphorus compounds. Due to this, it is classified as a mineral fertilizer.

Despite the fact that there is much less nitrogen, this does not prevent the soil and crop from being fully nourished. The fact is that nitrogenous substances are presented in ammonium form. This has the added benefit of prolonging the impact. The composition also included:

calcium;
sulfur;
zinc;
iron;
magnesium.

Based on the proportions of elements (AKF), two types of Diammofosk fertilizer mixtures are distinguished: 10-25-25, 10-26-26. The nitrogen component is represented by the smallest number.

Each formula takes into account that:

Nitrogen fills with useful elements, increases their impact on the soil, development and growth of fruits.
Potassium – nourishes roots and stems. Helps increase immunity, increases resistance to external factors that negatively affect flowering and ovary formation. Activates metabolic processes, improves the quality and taste of fruits.
The phosphorus component of Diammofosk is important for the formation of flowers and ovaries and is required throughout the growing season. If there is not enough phosphorus, then this promises many problems for the “green inhabitants” of the garden. A negative point is the fact that the element in its pure form is practically insoluble, but in the preparation it is presented in oxide form. This allows the phosphorus to fire faster.

If fertilizing with Diammofoska is applied, then there is a consistent effect on the crop. Initially, nutrition is delivered to the roots and green parts. Metabolism is immediately activated and immunity is strengthened. It is noted that the complex drug begins to work quickly, literally after application.

What it is

Externally, diammophos is a granular product that contains phosphorus and nitrogen. It is important to consider that many new gardeners often confuse the name diammophos with diammophoska. They are sure that this is the same remedy. However, this is a misconception. The ending “ka” does not indicate a change in name, but the presence of potassium in the fat. Diammophos is considered a fertilizer with a wide range of uses.

Pros and cons of use

Buying an agrochemical is absolutely easy. There is plenty of it in every agricultural produce store. It is rightfully considered the most popular fertilizer for its positive qualities when used, and not just for its low cost. Volume is offered from 1 kg to a ton and more. But let’s list the advantages of diammonium phosphate.

First of all, it is worth noting its versatility. Diammofoska is allowed to be used on all types of soil and applied to all known crops, including lawn grass.

Purpose and use in the garden: to ensure a balance of the necessary elements for the full development of plants and fruits. Restoration and improvement of soil occurs even on loamy and sandy loam soils.

Positive properties besides those already mentioned:

goes well with organics. Application will be more productive if organic fertilizers were used previously;
does not have a negative effect on plants, living beings (humans, animals, insects);
ease of use. It is enough to understand how to dilute, follow the rules indicated in the instructions for use;
increasing the shelf life of the harvested crop;
use on acidic soils is allowed, since the drug has low acidity;
has no chlorides;
rapid action and dissolution.

Diammofoska can be stored open for a long time, but subject to the conditions and rules. After the first year of applying the substance in the required dosages, the yield doubles in volume.

You can work with the drug throughout the year, and not just in spring or summer. It is recommended to use it for winter wheat.

There are much fewer negative aspects than similar agrochemicals. And the first is the chemical composition. Three times, an overdose should not be allowed; only strict adherence to the standards allows us to characterize the feeding as the highest class. And the last thing to remember: violation of storage rules leads to damage to the mineral fertilizer.

Norms for applying Diammofoska to the soil

To achieve the most effective result, experts advise calculating the exact dosage for fertilizing depending on the type of crop being treated. In this case, the application itself is carried out in two ways: near-trunk or root watering, as well as during digging.

Fruit trees

When treating fruit-bearing trees, fertilizer can be applied regularly throughout the season. In this case, the relevant dosage will be 30 g, diluted in 10 liters of water.

Berry bushes

Fertilizer is applied during loosening the soil layer in an amount of 10 g per square meter. When processing grapevines, Diammofoska is scattered on the snow at the first steady warming at the rate of 25 g.

Strawberries and wild strawberries

For berry crops, the optimal dosage is 10-15 g per 1 square meter. m. In this case, you should also apply the drug in dry form directly while loosening the soil.

Vegetables

For irrigation, 10 g of the drug granules and 500 g of rotted manure are dissolved in 10 liters of clean water, adding the resulting mixture twice a year. When digging, 30 g are used for each square meter of the greenhouse or 50 g for an open area.

Lawn grass

Diammofoska has also proven itself to be good for fertilizing lawns. In this case, fertilizing is provided twice: after the snow has completely melted and 300 g for each square.

Application for winter crops

For application to winter crops, the belt method with a 10-centimeter depression is used. In this case, for each hectare of wheat and barley, about 8 quintals of Diammofoska are required for spring digging and 4 quintals for autumn digging.

Safety and shelf life

Any chemical requires special storage and rules of use. Despite the fact that Diammofosk is declared as a safe fertilizer for all living organisms, the presence of special clothing and protection for mucous membranes is mandatory.

If the drug in any form gets into the oral cavity or respiratory tract, it is necessary to rinse and wash the mucous membranes. To prevent poisoning, it is recommended to drink a lot of water (1.5-2 liters) and induce a gag reflex. It is advisable to take adsorbents after gastric lavage.

Fertilizer storage includes:

well-ventilated area;
normal humidity;
the air temperature is not higher or lower than 25 degrees.

You cannot keep other medications, food or drinks near the package. The product bag must be well secured to prevent moisture from entering. After the expiration date, the substance must not be used.

Which plants to feed Diammophos

It was already mentioned above that ammonium hydrogen phosphate is suitable for feeding any plants. This fertilizer can be used to fertilize:

agricultural crops;
shrubs;
fruit trees;
ornamental plants.

Crops that do not tolerate chlorine respond well to fertilizer. Fertilizers in which it is present negatively affect their taste. Diammophos does not contain this chemical element, so it is not prohibited for feeding:

any fruit trees;
gooseberries;
tomatoes;
all varieties of currants;
wild strawberries and strawberries;
potatoes;
grapes

If fertilizer is applied to areas with potatoes, all the nutritional elements present in it are completely absorbed by root crops, crop growth improves, and productivity increases. Fertilizer provides scab prevention.

Grapes, which are known for their capricious character, respond well to feeding with diammophos. This fertilizer is much more effective than any type of superphosphate, as it saturates the grapevine with valuable nutrients.

Solution - diammonium phosphate

The diammonium phosphate solution for impregnation is taken at the rate of 4 - 5 liters of solution per 1 kg of dry fabric.

Then the diammonium phosphate solution is sent for crystallization, centrifugation and drying.

The overalls, immersed in a vessel with a diammonium phosphate solution, are allowed to be completely saturated with the solution, turning them over from time to time. Then the overalls are wrung out to remove excess solution and dried at room temperature.

Saturation scheme for capturing ammonia to produce salts.

The preparation of diammonium phosphate is complicated by the high pressure of ammonia vapor above the diammonium phosphate solution.

The package with the blanks is completely immersed in a bath of galvanized iron or wood and filled with a 20% solution of diammonium phosphate. The impregnation process lasts 90 minutes. After this time, the bag is removed from the solution. The completeness of impregnation is characterized by the cessation of the release of air bubbles on the surface of the solution.

To avoid loss of ammonia, saturation is carried out at a temperature below 80 C. Then the diammonium phosphate solution is sent for crystallization, centrifugation and drying.

To avoid loss of ammonia, saturation is carried out at a temperature below 80 C. Then the diammonium phosphate solution is sent for crystallization, centrifugation and drying. Diammonium phosphate is dried at 60 - 70 C to prevent loss of ammonia and conversion to monoammonium phosphate.

Technical ferrous sulfate and technical diammonium phosphate were used as raw materials. A 15% solution of diammonium phosphate was prepared in a reactor with a stirrer; a solution of iron sulfate containing 23% FeS04 was pumped into it from a solvent tank at such a rate that the drainage time was 15 minutes. At the same time as iron sulfate, ammonia gas was supplied; Duration of ammonia supply is 15 - 30 minutes.

Impregnation with diammanium phosphate maintains the breathability of the fabric. The impregnating composition dissolves in water and is washed off when washing the fabric. Therefore, after each wash, it is necessary to re-impregnate the workwear with a solution of diammonium phosphate.

The technical properties of upholstery artificial leather meet modern requirements: these materials have high strength, drapability, abrasion resistance, are resistant to soap solutions, gasoline and oil, are non-flammable, many of them are made in a tropical-resistant design. PVC], also by fire-resistant impregnation of the textile base with special compounds, for example a solution of diammonium phosphate and borax. Increased frost resistance of materials is achieved by increasing the content of frost-resistant plasticizers, for example dioctyl sebacate, in the coating formulation. To make materials resistant to mold fungi (tropicostasis), fungicides are introduced into the polymer composition and, in addition, the textile base is impregnated with special solutions.

In Fig. 8.7 shows a technological scheme for capturing ammonia in a circular ammonium-phosphate process. The gas, freed from tarry impurities and naphthalene, is purified from ammonia in absorber 1 with an efficiency of two or three theoretical plates at 40 - 45 C. The good solubility of monoammonium phosphate and diammonium phosphate in water (3 84 and 4 3 kmol / m3, respectively) makes it possible to achieve ammonia capacity 40 - 45 g of ammonia / dm3 versus 10 - 25 g / dm3 when trapping ammonia with water. The diammonium phosphate solution obtained in the absorber is mixed in pump 2 with crude benzene, which extracts the naphthalene and resinous substances carried away by the solution, is separated from the diammonium phosphate solution in settling tank 3 and sent for processing.

Tomatoes

Diammofoska has a positive effect on tomato yield

Tomatoes react positively to the application of diammofoska. A special effect is achieved by adding fertilizer to the soil during autumn cultivation. In the spring, 4 grams of the drug are applied to each seedling bush. After another two weeks, the procedure is repeated, especially if there are signs of nitrogen starvation.
