Every summer resident and gardener knows how difficult it is to find the right fertilizer for the soil. To do this, you need to have in-depth knowledge, as well as have a lot of practical experience. In addition, there is a wide variety of mineral dressings on the market today, so it can be difficult to understand and navigate correctly. In this article we will talk about superphosphate, analyze the composition and application process of this chemical. In addition, we will find out what effect the substance has on the plant and how to choose it correctly.

What it is?

Phosphates are mineral fertilizers, the main component of which is phosphorus. If we talk specifically about double superphosphate, then it is important to note the high concentration of phosphorus in it.

Double superphosphate is an essential component necessary for the full growth and development of plants . It provides the processes of energy metabolism in the cells of a living organism. At the same time, the plant grows faster, and the fruiting process is also accelerated. In addition, phosphorus is an element that not only in itself has a positive effect on a particular plant structure, but also contributes to the better assimilation of other useful microelements.

Thus, an experienced gardener cannot do without double superphosphate.

Pros and cons

Like any other fertilizer, double superphosphate has its advantages and disadvantages. Before using this chemical composition in your garden or in the garden, you need to familiarize yourself with the basic properties and characteristics of the substance - this will help you avoid possible negative consequences.

First, let's look at the benefits of using fertilizer

• First of all, it should be noted that double superphosphate, being an artificially synthesized chemical substance, does not contain any harmful components that can have a negative impact on human health. Therefore, you can be sure of the safety and environmental friendliness of the crop - do not hesitate to eat it yourself and treat children with fresh fruits and vegetables. But this is only true if certain fertilizer application rates are not exceeded.
• The relatively low price of the substance makes it available to representatives of almost all economic strata of buyers.
• Double superphosphate in specialized gardening stores is sold pre-packaged, which increases the convenience and comfort of using the fertilizer.
• Due to the fact that the solution is quite easy to use, it is chosen not only by experienced gardeners and gardeners, but also by beginners. The main thing is to follow the instructions clearly.
• Double superphosphate is a fertilizer that can be stored for a fairly long period of time. Therefore, you do not have to worry that it will deteriorate quickly.

However, in addition to the positive ones, one can also highlight the negative properties and characteristics of this chemical fertilizer

• It should be borne in mind that the use of feeding must be carried out strictly according to the instructions. Otherwise, a number of negative consequences may arise, including acidification and salinization of the soil.
• To achieve the desired effect in the shortest possible time, you need to apply fertilizer on a regular basis, which requires additional material, time and labor costs.
• Excessive fertilization has a negative effect on the general condition of the plants and on the quality of the products.

Thus, it can be concluded that the advantages significantly outweigh the disadvantages of double superphosphate. At the same time, improper use of top dressing can cause serious negative consequences. In any case, the choice is yours.

Impact

As mentioned earlier, double superphosphate is very popular among experienced gardeners and gardeners. And this is no accident. The fact is that the substance has a number of positive effects on the soil and plant. The main and most important of them include:

• acceleration of seedling growth;
• slowing down the aging process in mature plants;
• lowering the amount of nitrates in the crop;
• promoting the formation of high-quality fruits;
• increasing taste;
• improving the appearance of fruits, vegetables and berries;
• positive effect on plant immunity.

Receiving and composition

The double superphosphate formula is Ca (H2PO4) 2 x H2O. Thus, we can conclude that the composition of the substance includes such chemical elements as calcium, hydrogen, phosphorus and oxygen. With regard to the chemical composition of the fertilizer, it can be noted that 26% of double supersphosphate is pure phosphorus.

The production of double superphosphate is carried out in different countries and at different enterprises, therefore, the principle of obtaining a chemical substance may be different . If we talk about the Russian Federation, then the production of double superphosphate here is based on the decomposition of raw materials, followed by granulation and drying of the resulting pulp in a drum granulator-dryer.

Before carrying out the direct sale of the chemical composition, it is neutralized with chalk (or NH3). In general, the formula for the production of double superphosphate by the action of phosphoric acid on natural phosphates is as follows: Ca3 + 4H3PO4 = 3Ca (H2PO4) 2.

However, this method is not the only one. So, many manufacturers resort to the so-called chamber technique.

How is it different from simple superphosphate?

Beginners often confuse double superphosphate with simple superphosphate. However, these chemical compositions vary considerably. Above, we examined the features of a double substance, and now we will get acquainted with the main characteristics of a simple (or mono) superphosphate.

First of all, it should be noted that outwardly this substance looks like an ordinary and unremarkable gray powder. The main substance in it is significantly less than in double superphosphate - only 20% (compared to 26%). Monophosphate is easily recognizable by its pronounced acidic odor.

Its use is less effective than the use of a dual composition. On the other hand, this chemical is much cheaper, so it is popular with consumers. It is often used to enrich compost.

To quickly get a sense of which compound you are dealing with, throw the powder into the water. Simple phosphate will immediately dissolve, while double phosphate does not dissolve in water.

When and where to apply?

The use of double superphosphate in the garden or in the garden is recommended in autumn (during digging) or early spring (before planting directly). The most effective use of dressing for strawberries, raspberries, cabbage, carrots, tomatoes, bell peppers, eggplant, onions. Besides, double superphosphate can be fed to fruit trees (for example, cherry, apple, pear).

How to use it correctly?

It is necessary to apply double granular superphosphate to the soil as fertilizer strictly in accordance with the instructions. It is usually included with the substance.

Training

Before adding double superphosphate to the soil, it is important to carry out a preparatory stage. It can happen in different ways and depends on which method you choose to fertilize. We will talk about the preparation process for the most common top dressing among gardeners and gardeners - compost with double superphosphate.

To prepare this mixture, it is necessary to pour fertilizer into a suitable container and pour boiling water over it . In this case, it is recommended to use any container made of enameled iron or plastic. In this state, the resulting solution must be left for a day. After the specified time has elapsed, all the light liquid from the container must be drained, and later used for quick feeding.

Introduction

The procedure for applying a chemical to the soil can be carried out in several ways. Let's consider the main ones:

• as an additive to compost;
• by pouring into the holes when planting a particular plant culture;
• in the process of digging in the spring or autumn;
• scattering over the area of the site (in this case, the substance can even be scattered under the snow);
• in the form of a specially prepared watering solution.

In this case, it is necessary to take into account the application rates of this fertilizer. So, the most optimal amount of fertilizer that is allowed to be applied in spring and autumn is 50 g / m2. But this is provided that the soil is completely supplied with nutrients.

In the case of depleted soil, this amount of the chemical must be doubled. If you mix superphosphate with organic fertilizers, then stick to the following proportion: 100 g of fertilizer per 100 kg of organic matter.

What should be considered when buying?

There are several key parameters to consider when choosing and buying

• First of all, you should pay attention to the manufacturer of the product. It is recommended to give preference only to those brands that have proven themselves from the best side and enjoy high trust and respect among consumers.
• Be sure to read all the information on the label. Pay close attention to the expiration date. For example, if you use an expired product, then you can either not see any effect at all, or you can note a negative impact.
• To buy high-quality feeding, you need to contact only specialized stores and trusted bona fide sellers. Only then will you be able to purchase a really good fertilizer that will have the desired effect.

Thus, Double Superphosphate is a widespread and popular soil additive that has many beneficial effects on overall soil health and agricultural productivity . At the same time, you need to be especially careful when buying and using the product. Be sure to read the instructions for use, and if necessary, consult with specialists, and not with the sellers in the store. The main thing for the seller is to sell the product, and subsequent claims are usually easily refuted.
