The benefits of superphosphate extracts for tomato

Phosphorus is very important for a good harvest of tomatoes. But in ordinary soil it is not enough, therefore, they resort to phosphorus fertilizer of vegetables. Superphosphate is a fertilizer that contains many important trace elements and minerals, as well as phosphorus oxide. Superphosphate extract for tomato is easily absorbed by the plant and is well suited for feeding.

Use of hoods from superphosphate for tomato

Tatyana Orlova (Candidate of Agricultural Science j):

Phosphorus is required for tomato plants five times more than nitrogen. Phosphorus affects good root growth, which makes the plant more resistant to drought. Tomato fruits with optimal phosphorus nutrition become more sugary.

When an extract is used

Fertilizer is used for various vegetables, but for tomatoes it is most useful. The advantage of this fertilizer is that you can add it to the soil in large quantities. This will not harm the plant; it will take as much fertilizer as it needs. Tomatoes often die precisely because of its lack.

Tatyana Orlova (candidate of agricultural sciences):

Phosphorus, in contrast to nitrogen, is an inactive element in the soil. Phosphate fertilizers slowly dissolve in the soil and almost do not move deeper. Therefore, it can be applied in the fall under deep digging of the soil in multiple doses. It can be applied 2-3 times more than the rate of phosphate fertilizers in the autumn, and then not applied 2-3 years.

Signs of phosphate deficiency

With phosphorus deficiency in the soil, tomatoes develop slowly, the taste characteristics of the fruit are not of very good quality. There are such signs of phosphate deficiency in tomatoes:

• purple spots on the underside of the leaf;
• brown spots on the leaves and stems;
• the leaves become darker.

Typically, these symptoms appear after a cold snap or in plants that have been tempered. Due to the cold, the plants begin to poorly absorb useful elements. As a rule, after warming, the plants return to their normal color. But if this does not happen, you need to fertilize them.

Superphosphate for tomatoes is applied to the soil before planting in the spring or after harvesting in the fall to prepare the soil for the next season. It is better to fertilize tomatoes in the spring, phosphate is added directly to the hole when planting, 1 tsp is taken. per plant.

Types of superphosphates

Different types of phosphate fertilizers are used to fertilize tomatoes.For convenience, it is produced in various forms:

1. Monophosphate (simple). This is a gray powder, in which up to 20% of phosphorus. This type is not very effective, but it is often used because of its low price.
2. Superphosphate is simple in granules. It is convenient to use because of its good flowability. It contains about 50% phosphorus oxide and 30% potassium.
3. Ammonized superphosphate. Contains about 12% sulfur. Therefore, it is used for its deficiency in plants.
4. Double superphosphate. 50% composed of phosphorus oxide. There are few ballast elements in it, therefore it is advantageous in application. It contributes well to the development of the plant.

Fertilizing tomatoes with superphosphate

The plants become stronger due to the processing, and the fruits are juicy and sweet. Fertilizer should be applied at the rate of 20g / 1 plant.

Usually it is applied in a dry or granular form. Fertilizer is distributed evenly in the soil, do not deepen it much. It is best to add phosphate at the root level of plants. About 90% of fertilizers are used by the tomato to form fruits, so you need to apply during the entire flowering period.

Superphosphate is important for plant growth

Superphosphate gives a good crop, but it is better to use fertilizer with lots of potassium. It is also important for a good harvest as is phosphorus.But it is important to remember that adult plants absorb phosphorus better than young ones. This is due to the fact that the seedling system is still underdeveloped.

Before you start using superphosphate for young plants, you must first dissolve it.

How to make an extract from superphosphate

Superphosphate does not pass well into the dissolved form. Therefore, so that the granules dissolve faster, they are poured with hot water. When dissolved, the fertilizer does not lose its beneficial properties and is better absorbed by plants.

Tatyana Orlova (candidate of agricultural sciences):

An extract from superphosphate is used at the end vegetation of tomato plants to achieve fast, friendly and simultaneous ripening of fruits. The extract from superphosphate has the property of desiccation, because after its application, the leaves on the plant begin to dry out. Do not try to use it too early, for example, when the fruit has just formed.

After the fertilizer has been filled with water, you need to place it in a warm place for a day. To better dissolve it is necessary to periodically stir the solution. Ready top dressing should look like fat milk.

After this, the fertilizer is diluted with water at the rate of 20 tbsp. l. / 3 l of water receive a working solution from which the main fertilizer is prepared.150 ml of solution, 20 g of nitrogen, 0.5 l of ash are added to 10 liters of water. Nitrogen must be added, since phosphate will not be absorbed without it. Further, this fertilizer is applied by watering under the root, you can also spray tomato leaves with superphosphate.

It is better to fertilize 2 times, with an interval of at least 10 days. But you can’t apply a lot of different fertilizers in large quantities, otherwise the plant may not produce fruit at all.

Neutralization of an excess of phosphate

If many fertilizing preparations have been applied, this can be fixed 2 ways:

1. Do not water the week. But the air temperature should be kept at about 25 °. Conduct root dressing using 3 tbsp. l extracts on 10 l of water. Pour tomatoes with this composition, calculation of 1 liter per 1 plant.
2. It is important not to combine the extract from superphosphate with top dressings from urea, nitrate or chalk. At least a week should elapse between processing with these solutions.

Conclusion

The proper use of superphosphate for tomatoes is a very important procedure when growing crops. This is one of the most useful types of nutrition. Its advantages are in the optimal amount of phosphates in the composition, as well as potassium, nitrogen, sulfur and magnesium. Thanks to him, tomatoes develop correctly, the quality of the crop increases.

You can fertilize in various ways, both by watering under the root and spraying tomato plants with superphosphate.
