Ammophos: formula, application, composition and properties

Lack of fertilizers adversely affectsplants. When there is a shortage of phosphorus, productivity decreases and the plant's absorption of nitrogen and other nutrients decreases. The fertilization of ammophos, the formula of which is presented below, helps increase yield, normalize growth and development.

What is ammophos

Ammophos is one of the mosteffective types of phosphorus fertilizers, which are used in planting, as well as at different stages of vegetation. The ammophos formula is a complex concentrated compound obtained by neutralizing orthophosphoric acid with ammonia.

A well thought-out composition made it possible to create a very active phosphorus fertilizer with an easily digestible active substance. And this, in turn, increases the possibility of applying fertilizing.

The formula of ammophos is an unusual feeding forall types of plants, which can be used at any stage of vegetation. The phosphorus contained in the fertilizer dissolves easily in water and is quickly absorbed by the plant. It is especially important to give fertilizing to plants during the growth period. This time is considered critical and requires an increased content of phosphorus in the soil for normal development of the root system and better absorption of nitrogen.

Composition of top dressing

The formula for ammophos is as follows: NH4H2PO4 + (NH4) 2HPO4.

Here (NH4) 2HPO4 is monoammonium phosphate, and NH4H2PO4 is diammonium phosphate.

The formula of ammophos in chemistry clearly shows thatis a part of. In this fertilizer there are no ballast elements, which makes use an economical and correct solution. The substance poorly absorbs moisture from the air, but it dissolves very well in water. This property allows to apply the product in the form of solutions for foliar and root dressings.

The formula of ammophos was obtained by carefulwork. To obtain the substance, a chemical reaction of neutralizing orthophosphoric acid with ammonia is necessary. As a result of the reaction, about 10% ammonia and about 50% phosphorus are formed. This ratio is considered ideal.

Many believe that the formula of ammophos has a number of shortcomings. The main one is a low content of nitrogen (5 times less than phosphorus).

Physico-chemical characteristics

A special formula of ammophos allowed to obtain an unusual substance, useful for plants. The fertilizer has the following physico-chemical properties:

1. The substance is available in the form of granules about 3.5 mm in size.
2. The developed formula of ammophos made it possible to obtain an element that does not accumulate moisture from the air. Thanks to this substance can be stored for a long time.
3. Granules are dense, not friable, which simplifies the work with fertilizer. During the spillage of the substance, dust is not dangerous to humans.

Properties of ammophos

Fertilizer has a number of positive properties. The formula of ammophos allows to increase the yield and increase the resistance of plants to diseases.

The use of the substance makes it possible to strengthen the rootsystem of plants, improve the quality of fruits. After fertilizing, plants adapt more easily to any negative external conditions, while the yield and the period of their storage increase.

Instructions for use

According to the instructions fertilizer ammophos is not appliedonly as a basic top dressing, but also as a supplement. This substance contains a small amount of nitrogen, so to fill its deficiency it is recommended to add phosphorus. Usually, feeding is done in equal quantities. This ratio is suitable for all garden and garden crops. However, there are exceptions to this rule. For example, before sowing winter crops, it is enough to introduce only ammophos into the soil. Additional fertilizers are not required.

Use fertilizer can be on different types of soil, regardless of climatic conditions. In regions where dry weather prevails, it is recommended to apply the drug with a minimum amount of nitrogen.

It is recommended that fertilizer be applied to soils withalkaline and neutral medium. This substance has a beneficial effect on the plant. Nitrogen and phosphorus are balanced in the formula of ammophos. The chemical formula makes it possible to use the complex on a protected ground.

The main application of ammophos to the ground is made in the middle of spring and autumn (April, September). In the summer, the fertilizing of plants is carried out. The main application for vegetable crops comes out at a rate of 25 gr per 1 m². Top dressing is carried out on 5 gr in the aisles by the method of sealing granules to a depth of at least 6 cm.

For root crops, the main application is made at the rate of 20 gr per 1 m² of the soil. Summer fertilizing is carried out by embedding the granules in the soil to a depth of 8 cm (the norm of 5-10 g).

Fruit trees, bushes, berry crops are fertilized in spring and autumn at the rate of 30 gr per 1 m². In addition, in the summer period of time, 5 gr fertilizer is applied by the method of gravel packing in the soil.

Ammophos is suitable for fertilizing lawns, ornamental crops. 15 grams of pellets per 1 m are added to the main feeding². In summer, 5 gr fertilizer per 1 m².

What is fertilized by ammophos

Phosphate fertilizer is ideal for all types of plants. It is recommended to introduce it into the soil when growing the following crops:

1. Grapes. When using fertilizer, this culture is saturated with all the necessary nutrients. Fertilizers are introduced in the spring in several stages, previously diluting ammophos with water (400 grams per bucket of water). Two weeks after the first feeding, another one is carried out, diluting 150 g of fertilizer in a bucket of water.
2. Potatoes. Phosphorus fertilizer helps to increase the potato yield. For this, the granules are added directly to the wells at a rate of ½ teaspoon per well.
3. Beet. Using fertilizing allows you to saturate the roots with sugars, which is valuable when growing sugar beet. Top dressing is carried out at the rate of 5 gr 1 per m².

Also, fertilizing is carried out when growing cereals, sunflower, flowers, fruit and other plant species.

Use of fertilizer on different types of soil

For each type of soil, a certain amount of fertilizer is applied. For simple chernozem, steppe zone, it is recommended to use fertilizer without additional fertilizing, including nitrogen.

Meadow zones of chernozem, where flax, potatoes, beets, cereals are grown, fertilizer is added with the addition of phosphorus and nitrogen.

The unique formula of ammophos allows the use of fertilizer even on saline and sheltered soils.

On serozem and chestnut soils, the use of phosphorus fertilizer is carried out together with irrigation farming. Only in such conditions can you get a high yield.

In conclusion, it should be noted that the use offertilizer ammophos allows not only to increase yield, but also to raise the resistance of plants to various diseases. Working with granules is easy, the main thing is not to forget about the means of protection.
