Diammophos: composition, description of the drug and its use
Mineral additives are used exclusively for the rapid and productive growth of cultivated plants. Diammophos is considered an excellent example of complex fertilizers rich in important nutrients: nitrogen and phosphorus. The fertilizer is environmentally friendly, helps to accelerate the processes of flowering, fruit set, and has a positive effect on their taste characteristics.
Medication description
The drug appeared on sale a long time ago, however, it did not gain much popularity among gardeners due to the great competition from more popular analogues.
What is this?
In appearance, Diammophos is small granules of white, gray, yellowish or pink tones, which include the three most important macronutrients: nitrogen, phosphorus, potassium.
Diammophos is classified as a complex preparation with a wide range of applications. It is suitable for most horticultural crops, and is successfully used on any type of soil.
Characteristic
Diammonium phosphate is obtained by complex chemical transformations in which phosphoric acid is neutralized with ammonia. In this way, a water-soluble grayish (less often pink, yellowish, white) s alt is obtained in the form of small granules (up to 0.5 mm). It has excellent flowability (up to 100%) and a melting point of +155 ºC.
Composition
Fertilizer includes three major macronutrients: phosphorus, potassium, nitrogen. The last element is less, because the drug is often referred to as phosphorus-containing top dressing.
When fertilizing the soil with diammonium phosphate, it should be borne in mind that the composition still contains trace elements: magnesium, sulfur, iron, calcium, zinc. The percentage of the latter is approximately the same. Therefore, the use of this preparation covers the needs of cultivated plants in the main macro- and microelements, additional mineral supplements are not required.
Benefit
Often, Diammophos is used as an independent top dressing, less often - as part of other complexes:
- The presence of the main macroelements in the preparation guarantees a complex effect on cultivated plants. The latter grow well, become more resistant to diseases and attacks from pests.
- Fruits accumulate sugar more easily, become juicier and tastier.
- Garden crops are gaining resistance to temperature fluctuations, prolonged heat, prolonged rains.
- There is no accumulation of harmful substances in the crop.
- The drug is non-toxic, which guarantees the ecological purity of the grown products.
- Perfectly combined with organic fertilizers: bird droppings, rotted manure, compost.
- Retains in soil, resistant to washout. Provides plants with nutrients at all stages of growth and development.
Application of ammonium hydrogen phosphate for plants
The use of Diammophos is justified for all types of cultivated plants that do not tolerate chlorine well. Very responsive to fertilizer vegetables, berry bushes, greens.
The drug is used both for processing large areas (in the fields) and for growing cultivated plants in small garden plots.
Diammophos gives the best results in nitrogen-rich lands. Or in combination with organic top dressing. This is especially true in regions with prolonged rainfall. Due to the competent combination of organic matter and minerals, there is no washing out of useful elements from the soil. Because plants grow well without experiencing nutritional deficiencies.
Diammophos increases the yield of all crops. Improves the quality of the crop, the germination of grown seeds. Along with this, the immunity of plants increases, making them easier to resist adverse environmental factors.
Agriculture
Diammophos is recommended to be applied in spring or autumn. After the snow melts, the preparation is evenly scattered over the area before planting. The optimal dosage of fertilizer application is a large spoon per meter. This is usually done before spring digging.In the absence of precipitation, watering is recommended so that the active substances dissolve and give all the nutrition to the soil. In addition, watering is also recommended in order to prevent burns of the root system of seedlings.
The drug reanimates weak, diseased trees and shrubs that grow slowly and experience a sharp nutrient deficiency.
Berry crops are especially responsive to its introduction: gooseberries, raspberries and currants. A couple of large spoons per square meter is enough. m. The same dosage is applicable for vegetable crops.
Diammophos is also fertilized with indoor plants and garden flowers. Thanks to intensive nutrition, they grow faster and tie buds.
Industry
Ammonium hydrogen phosphate is found not only in agriculture. Also used for industrial purposes:
- As a food additive for livestock (as preservative E-342). The maximum dosage of consumption of this substance is 70 mg per 1000 g of body weight per day. The preservative is approved for use in most developed countries of the world.
In addition, they are used in the manufacture of dairy products, bakery products, canned meat and fish, refreshing drinks, dietary supplements. The drug regulates the level of acidity of food, improves the properties of products.
- Food diammonium phosphate acts as a means of obtaining alloys of some metals. Among them are zinc and bronze, copper and tin.
- The drug is used to process some materials that are sensitive to elevated temperatures. It has flame retardant properties, used in the production of textiles, paper products.
- In the pharmaceutical industry to prevent caking, lumps.
- In the technical field, in particular, in the production of devices that apply the characteristics of ferroelectric, piezoelectric.
Application on various types of soils
Diammophos is quite suitable for any type of soil. In arid regions, the drug is applied deeper, and in areas with heavy and frequent rains, it is scattered over the surface. The greatest effect from the use of the drug is observed on lands rich in nitrogen: peat bogs, fallow or old arable land.
Light soils and fallow fields in irrigation
In this case, Diammophos is used only after a competent and accurate calculation of the dosage. If you exceed the amount of application, there will be a loss of nitrate nitrogen. In some cases, this loss reaches 20%.
Ammonium hydrogen phosphate is introduced into the soil in order to enrich it with useful elements.This is especially true in the spring before the main sowing work on the site. The drug is also used to feed plants in the active growth phase. It is one of the few chemicals allowed to be combined with irrigation.
Behavior in soil
Diammophos, getting into the soil, decomposes into ions. Disubstituted ammonium phosphate and Ammophos - for ammonium ions NH4+ and orthophosphoric acid: H2PO4 -, HPO42- and PO43-.
Potassium compounds
The potassium compounds included in the active composition of the preparation decompose in the soil into a positively charged potassium ion, a sulfo group or a phosphate ion. It all depends on the compound used to make K.
Ammonium ion
It is known that this ion in soils of any type (with the exception of light soils with low absorption capacity) is rapidly absorbed by the soil, losing its former mobility. In the off-season, this property allows you to save nitrogen in the ground. After winter, in about 6 weeks, due to the transformation during nitrification, nitrate nitrogen forms are formed.
Nitrates are completely absorbed by garden crops, as well as soil microflora. A small amount of nitrogen is lost when washed out.
Phosphoric acid ions
Able to be absorbed by horticultural crops, but with varying degrees of efficiency. So, H2PO4 can be absorbed more easily, faster than others, HPO42 is much narrower, and PO43 is not absorbed by plants at all.
All ions not assimilated by crops eventually form stable soil compounds. This happens either through exchange absorption, or by chemical bonding. Phosphorus of the exchange type is more accessible to horticultural crops.
Potassium compounds
They are characterized by low mobility along the soil profile (exceptions to the rules are sandstones and sandstones).
The potassium ion is extremely active, coming into contact with the PPC in two main types of absorption at once.
Exchange Absorption
This process is about potassium. It is reversible, insignificant, not subject to leaching from the arable land layer. Therefore, it is more available for absorption by plants.
The reverse process favors the displacement of K from the PPC, this is also helped by the isolation of rhizomes of garden crops. This will lead to acidification of the soil solution, which is especially important for acidic soil, where aluminum and hydrogen are not observed in the composition of the FPC.
If used for a long time for potassium-loving plants, the soil will slightly acidify.
Non-exchangeable potassium
Almost devoid of mobility, plants are unable to assimilate. Such potassium is fixed in clay-containing soil minerals. The level of fixation reaches 82% and is directly dependent on the size of the feed particles.
Thus, coarse-grained forms, as well as granules, have less contact with the soil, and therefore reduce the level of potassium fixation.
Application on various types of soils
When using Diammophos on your site, do not forget about the type of soil and the level of fertility. The drug contains more phosphorus than nitrogen. On soils that are deficient in the last macronutrient, it should be used only in combination with other fertilizers. For example, with organics.
In general, Diammophos is considered a universal mineral fertilizer that can improve the qualitative composition of soil of almost any type.
Normal application of diammophos per 1 m2
When using the drug, follow the dosages indicated on the package.
Application rates are usually universal for all soil types:
- In the spring, before digging the site - 25 g per sq. m.
- For fruit trees over 2 years old, 20 g is enough. Fertilizer is usually sprinkled on the trunk circle, slightly embedding the granules in the ground and carefully spilling.
- For planting strawberries, apply up to 7 g of fertilizer per meter of bed.
- Potato - 8 g per square. m.
- For greenhouse plants - 35 g per sq. m.
In the absence of precipitation, the area sprinkled with Diammophos must be watered abundantly.
What to do with an overdose
Diammophosphate allows plants to grow rapidly, bloom together and bear fruit abundantly. However, use it in moderation.
Overdose of the drug negatively affects the taste of garden crops, changes their color to atypical, negatively affects the volume and duration of storage of the crop.
In case of excessive application of Diammophos, planting of vegetable and fruit crops is not recommended. It is better to let the soil rest for 1-2 years. Some gardeners use this time to plant green manure and comprehensively improve the soil.
Applying methods
Gardeners usually apply the drug in different ways. Among the main methods are the following:
- Root top dressing. Diammophos is preliminarily diluted in water and the plants are fertilized with this composition.
- Before digging by scattering over the site. This method of fertilization is one of the most common due to its simplicity and efficiency.
- Foliar application. Some horticultural crops prefer summer foliar feeding along with traditional root dressing. Knowing this trick, gardeners manage to get a bountiful harvest.
Diammophos is applied at all periods of plant vegetation. In addition, this substance is successfully used for protected ground.
Crop usage guidelines
The use of ammonium hydrogen phosphate has its own subtleties and nuances that must be taken into account when growing each particular crop.
Rice
Diammophos is actively used in the cultivation of this moisture-loving crop. The drug is resistant to leaching, and therefore perfectly copes with its main task - it nourishes the plant with the necessary useful components.
In addition, it allows rice to gain strength, acquire rich green mass, and increase yields. The drug prevents the accumulation of nitrates. Rice grown on Diammophos is absolutely safe for he alth.
Grapes
This plant is distinguished by its finicky and sensitivity not only to growing conditions, but also to nutrition. However, Diammophos is perfect for grapes, because the culture loves phosphorus. And not every analogue contains so much of this macroelement.
If you combine the drug with organic fertilizers, the grapes will grow better, bear fruit and respond more easily to changing weather conditions. The application rate is indicated on the packaging, often determined by the age of the crop.
Potatoes
It is known that Diammophos is universal, however, some root crops are especially fond of it. This applies to potatoes, which begin to sprout together, grow confidently and bear fruit. Its structure and taste improves, the shelf life increases.
Diammonium phosphate is usually applied to the soil in the spring before plowing. Dosage - 25 kg per hundred square meters. Some gardeners pour fertilizer into the holes (6 g each) directly at planting.
Another way to fertilize potatoes is to sprinkle the area plowed under potatoes just before planting. The powder is incorporated into the soil during harrowing. The consumption of the drug - 20 g per square. m.
Cabbage
It is known that cruciferous plants do not tolerate chlorine. The latter is often included in potash supplements. Diammophos, in this regard, is one of the most successful fertilizers for cabbage. It contributes to the rapid tying of forks, protects against pests and diseases by positively influencing the immunity of a vegetable crop:
- in the spring, when digging the site, it is recommended to apply up to 35 g of fertilizer per square meter. m;
- directly into the holes when planting - 4 g per root;
- for autumn cultivation of the area for planting cabbage - 40 g per sq. m.
Tomatoes
Tomatoes are grown almost everywhere in Russia. They are planted both in greenhouses and in open ground. For tomatoes, complete feeding with minerals is important, since the plant spends a lot of strength and energy not only on growth, but also on the ovary. The use of Diammophos has a great effect on the yield of tomatoes. So, nitrogen nourishes, promotes rapid growth, potassium improves the structure of fruits and their taste, phosphorus promotes the development of a powerful root system responsible for the delivery of nutrients.
Application dosages:
- in the spring before digging an open area - 25 g per sq. m, closed (greenhouses) - 55 g per sq. m;
- directly into planting holes: 4g/m (outdoor), 6g/m (indoor).
Strawberry
This plant is in great need of minerals, through which it is possible to get a large and rich harvest.
Diammophos is a good top dressing for strawberries, due to the presence of the main macro- and microelements necessary for the culture for normal growth and fruiting. In addition, the drug prevents the accumulation of harmful substances in the berries, which is extremely important for he alth.
Use top dressing in a diluted form and by scattering (application rate - up to 20 g per sq. m).
Lawn
Green carpet needs constant mineral nourishment to build up juicy mass. Especially after the winter period and seasonal haircuts. Feed in several stages.
In the spring, it is preferable to spread s altpeter (3500 g per hundred square meters) followed by watering, in summer - the use of Diammophos (4000 g per hundred square meters).
In autumn, it is better to use diammonium phosphate, but at a lower dosage (2500 g per hundred square meters). The drug will help the lawn to prepare for a dormant period, it is better to endure the winter cold.
Safety precautions
When working with chemical compounds, care must be taken. Diammophos is no exception. Causes allergic reactions on contact with skin. Therefore, it is recommended to use protective equipment: gloves, bandages, raincoats (when spraying the active substance with a sprayer).
Storage rules
Because Diammophos is soluble in water, it should be kept in a dry, well-ventilated place. The optimum temperature is up to +30 ° C, direct sunlight is highly undesirable. The drug is non-toxic, does not ignite when heated and does not explode. Therefore, many gardeners leave it in the house for the winter.
Disposal
After the expiration of the storage period, it is better to dispose of Diammophos, since the drug loses its useful properties and becomes useless for application to the soil. It is forbidden to dispose of chemical compounds in the ordinary garbage. It is better to take it to special points for the disposal of such drugs.
Diammophos is considered a universal fertilizer, the use of which increases the yield of garden crops, has a positive effect on their taste. Top dressing is used in large agro-complexes and in compact household plots. The drug quickly dissolves in moist soil, quickly enters the plants. Can be used on any type of soil throughout the growing season.
