All gardeners who grow tomatoes in their area, are wondering what to choose for top dressing for these vegetables. Many chose the complex mineral fertilizer - nitrophoska or nitroammofoske. These are identical substances that increase the quality and fertility of the soil. As a result, it is possible to significantly increase the yield of tomatoes. This article contains information on the use of nitrophoska as fertilizer for tomatoes.

The composition of nitrophoska

This fertilizer is a mixture of mineral substances necessary for the growth and development of various crops. The main components of nitrophosphate are potassium, nitrogen and phosphorus. Without these minerals, simply no cultivated plants could grow. Fertilizer is sold in granular form. It is easily dissolved in water, and easily washed out of the soil. This means that the period of fertilizer impact on the shoots is very short.

Despite the sizes of granules, they contain the whole complex of mineral substances. The composition of nitrophoska includes the following substances:

  • ammonium and potassium nitrate;
  • potassium chloride;
  • ammonium phosphoric acid;
  • suurephosphate;
  • phosphorus precipitate.

These are the main components to which other minerals can be added for a particular vegetable crop or soil type. For example, almost all manufacturers of nitrophosphates add magnesium or copper, sulfur, zinc, and boron to the fertilizer. Determine the amount of each item by numerical designation on the package.

Disadvantages and advantages

Like all mineral supplements, nitrophoska has some pros and cons. The positive properties of this fertilizer include the following properties:

  1. Basic minerals constitute at least 30% of all components. Due to this, vegetable crops begin to develop at an accelerated pace.
  2. Until the expiration of the storage period, the fertilizer maintains flowability, does not stick together and does not cake.
  3. Balanced amount of all substances included.
  4. The presence of basic minerals - potassium, nitrogen and phosphorus.
  5. Ease of use.
  6. Easy solubility.
  7. Yield increase.

Depending on the plants themselves, the yields may increase by both 10% and 70%. Of course, nitrophoska has some drawbacks, but many gardeners are so in love with this fertilizer that they do not attach much importance to them. So, the obvious disadvantages of nitrophoska include the following factors:

  1. All components are exclusively chemical.
  2. Contributes to the accumulation of nitrates in the soil.
  3. If you violate the rules of use can lead to the appearance of nitrate compounds in the fruits themselves.
  4. Fertilizer can be stored no more than 6 months.
  5. Explosiveness and flammability.
  6. The need to follow precautions when using fertilizer.

Types of nitrophoska

The composition of nitrophoska may be different. There are such basic varieties:

  • sulfate nitrophoska. It is immediately clear from the name that sulfur is present in this fertilizer, which helps plants to synthesize plant proteins. This fertilizer is used to feed cucumbers, zucchini, cabbage, tomatoes and legumes. By applying fertilizer directly during planting, it is possible to strengthen their immunity and protect against pests;
  • phosphate rock. This nitrophoska prepared on the basis of phosphorus, which is simply necessary for the formation of fiber in vegetables. This nitrophoska best suited for fertilizing tomatoes. After using this fertilizer, you should expect tasty and large fruits. Moreover, these tomatoes are stored longer and remain fresh;
  • sulfate nitrophoska. This fertilizer, in addition to the main components, contains calcium. It is this mineral that is responsible for the flowering process, leaf size and flower opulence. Such properties make sulfate nitrophosphate just the perfect fertilizer for decorative flowers and other flowering plants.

Nitrofoski application

As you can see, nitrophoska, like its counterpart - nitroammofoska, is suitable for fertilizing a variety of crops. It can be made before planting, directly during planting, and also for additional feedings throughout the entire growing season.

Important! Remember that each type of nitrophoska is suitable for certain vegetable crops. Ask the seller what exactly you want to use the nutritional complex for.

Choose nitrophoska should also be based on the general condition of the soil. It is necessary to determine in which elements there is a need. Basically, gardeners use nitrophoska with an equal amount of three main components - phosphorus, potassium and nitrogen. This feeding has a positive effect on the soil as a whole, and also helps plants in the development of the root system and green mass.

If the soil is very poor, then you can pick up fertilizer, which will align the mineral composition and increase the fertility of the soil. For example, a soil with high acidity needs more phosphorus. Therefore, choosing nitrophoska, you should pay attention to the content of this element in it. If you notice that the plants in your garden bed often get sick, which can be manifested by yellowing of leaves and lethargy, it is better to opt for a nitrophoska, which includes magnesium and boron.

You can make a nitrophoska or nitroammofosku in the following ways:

  • scattering granules on the soil surface;
  • placing fertilizer on the bottom of the pit when planting seedlings;
  • in the form of water solutions, making watering.
Important! The way of using nitrophosphate depends on the characteristics and quality of the soil.

The first method is more suitable for loose and light soil. In this case, the nitrophoska can be simply scattered over the surface of the soil in the spring. This will prepare the soil for planting different crops. If the soil is quite solid, then the feed begins to make in the fall, burying it in the soil when digging.

Various fruit trees, perennial berry bushes and grapes are usually fertilized with nitrophosphate in autumn and spring. Plant nutrition in the autumn helps to prepare trees and bushes for the winter, so that they can easily adapt to new weather conditions. Spring dressing will help the plants to form buds, and later also fruits. Nitrofoska will fill a lack of the major minerals and will give strength to long-term bushes. Many gardeners use this fertilizer when growing indoor plants. Nitrophoska is great for garden flowers, especially roses.

The main thing when using such feeds, not to overdo it with the dosage. Remember that nitrophoska is a chemical fertilizer, which consists of nitrates. Excessive use of fertilizers will contribute to the accumulation of this substance not only in the soil, but also in the fruits themselves. Such vegetables are unsafe and can adversely affect human health.

Regardless of the form in which fertilizing is applied (dry or soluble), this should be done no more than 2 times during the whole season. Only in this case can good results be achieved without harm to health. Using dry granules for soil fertilizer, you can take no more than 100 grams of nitrophoska per 1 square meter of bed. And 10 liters of solution accounts for only 40 to 60 grams.

The use of nitroammofoski for fertilizing tomatoes

Nitrophoska great for feeding tomatoes. This fertilizer fully meets all the needs of this crop. It is able to provide tomatoes with all the necessary nutrients. Growing tomatoes for industrial purposes, it is easiest to simply sprinkle fertilizer on the ground in a dry form. It is better to do this in the spring to prepare the field for planting tomato seedlings. In areas where the tomato is grown a little, you can pay more attention to the culture. In such cases, fertilizing is introduced into the wells during planting.

Attention! For tomatoes, phosphoric nitrophoska is best.

When using fertilizer, care should be taken not to exceed the desired amount. It is very easy to feed the tomatoes with nitroammophoska, because the fertilizer is sold ready-made and does not require the addition of additional mineral substances. To feed the tomatoes, you need to mix a tablespoon of nitrophosphate or nitroammofoski with the earth, and then place the mixture on the bottom of the fossa. After which you can immediately begin planting tomato seedlings.

You can also carry out supplementation with a solution of this fertilizer. To do this, combine 10 liters of water and 50 grams of nitrophoska in one container. The solution is stirred until complete dissolution of the granules, and then pour it into each well. For 1 bush tomato will need about a liter of this solution. The next and last feeding of this mixture is carried out only 2 weeks after planting the tomato.

"Relatives" nitrofoski

Today there are a large number of mineral complexes, in their composition resembling nitrophoska. The difference between these substances lies in the presence of additional mineral substances or in the ratio between the main components. The most common are the following fertilizers:

Azofoska

This fertilizer, like nitrophoska, has three main elements - nitrogen, potassium and phosphorus. Therefore, some attribute them to the same class. The difference in these mixtures is really insignificant. The differences include the fact that phosphorus in azofosk is completely absorbed by plants, but only partially in nitrophoska. Azofoska also contains sulfur, and it is a part of nitrophoska in sulphate form.

Ammofoska

This fertilizer also consists of three main components, as in the previous cases. But there is one significant difference, which makes gardeners prefer ammophoske. Nitrogen in this case has an ammonium form, so that nitrates do not accumulate in the fruit. Fertilizer contains at least 14% sulfur. It also contains magnesium. The advantages also include the fact that Ammophos does not contain chlorine, sodium and ballast substances. This allows the use of fertilizer on different types of soil. Ammofoska excellent for plant nutrition in greenhouses. Due to the fact that there is no chlorine in the composition, it can be safely used for such sensitive plants as currants, potatoes, tomatoes, gooseberries and grapes.

Nitroammofosk

As mentioned above, these fertilizers are almost identical. They consist of the same basic components and differ only in the ratio of the number of some of them. The differences also include the absence of magnesium in the composition. But at the same time, fertilizer nitroammofoska contains a large amount of sulfates. It is not so quickly washed out of the soil, so that it can last longer on plants.

Nitroammophos

This fertilizer differs from the previous one in the absence of potassium in its composition. This composition does not allow a very wide use of this mineral complex. Applying it on your plot will most likely have to additionally add potassium to the soil.

Ammophos

This fertilizer is also a two-element. It contains phosphorus in large quantities, as well as nitrogen. This concentrated fertilizer is obtained by neutralizing orthophosphoric acid with ammonia. The advantage of ammophos over nitrate fertilizers is that all its components are easily absorbed by plants.

Although these fertilizers are not significantly different from each other, but thanks to this diversity, you can choose exactly the complex that is most suitable for your soil. Manufacturers tried their best and met the needs for any type of soil.

Nitrophosphate storage

It has already been mentioned above that nitrophosphate refers to explosive substances. Under no circumstances should fertilizer be heated. Keep the substance should be in cool concrete and brick rooms. The air temperature in such places should not exceed + 30 ° C. Also important is the humidity of the air, which can reach no more than 50%.

It is difficult to predict the effects of the interaction of nitrophoska with other chemicals. Therefore, these fertilizers should be stored separately. Wrong neighborhood can cause a fire or explosion. In the room where nitrophoska is stored, there should not be any heating devices and appliances. Fertilizer should not be near open flame.

Attention! After the expiry date, the substance becomes even more explosive.

The shelf life of nitrofoski - no more than 6 months. After the expiration of this period, the fertilizer simply loses its properties. It is possible to transport fertilizer both packed and simply poured into containers. It is advised to use for this purpose only ground transportation.

Conclusion

Nitrophoska or nitrophoska is a universal complex mineral fertilizer, which includes all the substances necessary for the growth of tomatoes. With it, you can achieve high yields and increase the fertility of the soil on your site.
