Phosphorus is an indispensable element for the life and development of plants. It participates in photosynthesis, energy and metabolic processes, provides nutrition for plant cells, strengthens young plants, and prevents the development of diseases. Initially, the soil contains very little phosphorus (1%), so only phosphorus fertilizers can compensate for this deficiency. The most popular and versatile phosphate fertilizer is superphosphate. This is a preparation based on nitrogen-phosphorus compounds with a complex of minerals and trace elements that accelerate the process of plant development. The action of superphosphate is aimed at the growth and strengthening of the most important organs: the root system, young shoots, flowers and the ovary. Fertilizing the soil with superphosphate helps to grow healthy crops, and get a high yield from them in the future.
The main component of superphosphate is phosphorus. Its content varies from 26 to 50%, depending on the type of fertilizer. The second component of superphosphate is nitrogen, its concentration is 6-17%. The fertilizer also contains some trace elements usually found in phosphorites: magnesium, calcium, potassium, sulfur. Fertilizer is a complex mixture that has two main types:
On sale you can find several types of fertilizers with additional components: ammonized superphosphate (contains 1.6% ammonia, used to neutralize soil acidity), and superphosphate with humates (humic acid salts, used to increase soil fertility).
How to prepare plants for the winter period with the help of dressings.
Phosphorus is extremely necessary for horticultural and horticultural crops during the transition from the phase of active vegetation to the phase of ovary and fruiting. Superphosphate has a well-balanced composition of nutrients in an accessible form, therefore feeding with a mixture has the most beneficial effect on crops:
For young plants, phosphorus fertilization is of particular importance - phosphorus contributes to the development of an underground root part, which is very important for seedlings grown in artificial conditions and greenhouse crops. Autumn top dressing of the soil with superphosphate will help grow high-quality root crops. With a phosphorus deficiency, potatoes and beets become stained, and black blotches form inside. The blue of the leaves of garden crops or home seedlings also indicates insufficient soil fertilization with phosphorus.
Superphosphate is a universal complex mixture that can be used as a fertilizer for the soil, as well as for feeding fruit trees and garden seedlings. Fertilizer can be applied to any soil, however, it should be borne in mind that on acidic soil this top dressing is weak. Experienced gardeners fertilize acidic soil with superphosphate only after adding ash or lime - these materials help to equalize the pH of the soil, and thereby increase the effectiveness of superphosphate.
Simple superphosphate is fed by directly introducing it into the holes or rows intended for planting seedlings. The granular preparation can be used to prepare a solution for foliar dressing (spraying). Phosphorus fertilization has some features:
Fertilization rates are as follows:
Phosphorus is not a readily soluble substance. Experienced gardeners feed the soil with superphosphate from autumn, so that until spring it dissolves and becomes active under the influence of moisture. But how, then, to carry out spring and summer fertilizing of plants with phosphorus? - this question made gardeners and gardeners look for ways to quickly assimilate superphosphate.
Any fertilizing, including phosphorus, is absorbed by the plants from the soil with the help of root hairs, so it is obvious that for them the only available form of fertilization is a liquid solution. If superphosphate is dissolved in water before being introduced into the soil, you get a concentrated extract with a high content of easily assimilable phosphorus. You can prepare the solution as follows:
Phosphorus extract is fed taking into account that 100 ml of fertilizer contains 20 g of pure phosphorus, and this amount, diluted in 10 liters of water, is sufficient to treat 1 sq. M. soil. The most effective working solution is obtained if liquid fertilizing is diluted in a ratio of 2 tbsp. spoons / 3 liters of water. A large bucket of water will require at least 150 g of the hood. An extract of superphosphate is used to fertilize the soil, and also carry out foliar dressing. The solution is quickly absorbed and has a long aftereffect, therefore it can be considered an ideal option for both garden trees and vegetable seedlings.
Informative video, what you need to know about phosphorus plant nutrition.
Superphosphate is considered a not very complex fertilizer, the main substance of which is phosphorus. Usually this top dressing is applied in spring, but superphosphate is often used both as autumn fertilizer and fertilizer in the middle of the season. In addition to phosphorus, this fertilizer contains nitrogen in a small dose. Considering this, when applying fertilizer to the soil in the autumn, you need to be careful and try to apply it at this time either in small doses, or fertilize the soil with it intended for planting spring crops.

Phosphorus is one of the main nutrients of plant organisms, it is vital at all stages of development. Tomatoes are a crop especially sensitive to its lack. Superphosphate Application:
Tomatoes are especially sensitive to phosphorus deficiency in the early stages of development, during root formation.
The existence of any living plant is threatened without the presence of phosphorus. This element provides energy exchange at the cellular level, as a result of which the transition from phase to phase occurs several times faster. This means that the crop grows faster and immediately begins to bear fruit.
Receiving phosphorus in sufficient volumes, the root system more actively assimilates a number of other macro- and microelements, which it cannot do without.
Did you know that this element contributes to the balancing of nitrogen, which leads to a significant decrease in the content of nitrates in the manufactured products, and therefore, to obtain quality food for humans and animals?
Several types of superphosphate are available to agricultural professionals and amateurs today. These differences depend on the method of obtaining fertilizer, production technology and indications for use. The most commonly used types are:
Monophosphate is produced as a gray powder. The substrate practically does not cake if the moisture content of no more than 50% is observed in the storage location. Simple superphosphate contains 10% - 20% phosphorus, about 8% nitrogen, no more than 10% sulfur, a significant amount of calcium sulfate, which is in the substrate in the form of gypsum. Has a pronounced acid smell.
Monophosphate is less effective than double and granular superphosphate. However, its inexpensive cost makes it in demand in large farms and industrial agriculture. It is used for the enrichment of composts and plant dressings, as it dissolves better in water than double and granular types.
Granular (Ca (H2PO4) 2-H2O + H3PO4 + 2 CaS04) is made from monophosphate. The feedstock is moistened, pressed, then rolled under industrial conditions. The amount of phosphorus can reach 50%, calcium sulfate - 30%.
The granular form is more convenient to use and store. Has a more prolonged action, as the granules dissolve more slowly in water and soil. The effect of feeding can last for several months. The granular species is especially appreciated for growing cruciferous, legumes, bulbous, cereals.
The advantage of double superphosphate (formula - Ca (H2PO4) 2H2O) is the minimum amount of impurities, which makes its use more profitable in economic terms. Differs in a high content of easily assimilable phosphorus and water-soluble calcium.
Differs in high nitrogen content - up to 20%, contains no more than 6% sulfur.
Double superphosphate application rates - table
Ammonized species (formula - (NH4H2PO4 + Ca (H2PO4) 2 x H2O + CaSO4 + H3PO4)) is used for growing cruciferous and oilseeds, which require an increased sulfur content. As part of this species, the amount of sulfur can reach 12%, calcium sulfate - up to 55%.
There are other types of superphosphate, for example, containing boron, magnesia, molybdenum. These species are used in the cultivation of certain crops to feed plants with additional microelements.

Phosphorus is characterized by poor solubility in liquids, and the preparation of a solution allows the substance to be used with greater efficiency. To prepare extracts from superphosphate, there is a relatively simple method that can be used at home.
For dissolution in water, it is necessary that the liquid is heated to a high temperature. To achieve the desired effect, it is enough to fill the granules with boiled water. After this procedure, the substance acquires a form that is easier to assimilate and retains the most important beneficial trace elements.
Cooking takes place in several stages:
Readiness is evidenced by the receipt of a liquid similar to fatty cow's milk. The standard dose used is 20 tbsp. l. for 3 liters of water. In the future, to prepare a working solution, mix 150 ml of the concentrated substance, 20 mg of fertilizer with nitrogen, 500 ml of ash and 10 l of water. The addition of nitrogen preparations to the fertilizer is a mandatory component of successful application, since otherwise phosphorus will be poorly absorbed.
When dissolving superphosphate compounds, one should not expect that the substance will completely turn into a liquid. It is enough to transfer most of the granules to a liquid state, and a small sediment is a normal state.
A mixture of phosphorus and nitrogen should be used in the spring as a top dressing under the rhizome, since plants during this period are in the phase of active growth and experience an acute deficiency of nitrogen and phosphorus. Phosphorus compounds are prone to gradual assimilation by plants, its effect lasts up to 2 months, and sometimes several years. Even when phosphate is processed into an easy-to-digest form, it is still not fully absorbed. Superphosphate extract is an excellent fertilizer for various garden and garden plants with a prolonged effect.
There is an additional method of transferring superphosphate to a liquid state - to use special biobacteria. To carry out the procedure, you will need to compost the chemical with Fitosporin or Humate. After the end of the action, you can get a convenient mixture that can be diluted even in warm water. The substance should be kept for 1 day.
The most successful people in vegetable growing are people who love nature, have a special vision of the most insignificant changes in plant life, are able to evenly distribute physical activity, and patiently do their work.
All these qualities are possessed by Oleg Ivanovich Pomidorkin - an active person, a graduate, a true expert in his field. But the work of a vegetable grower, like any other work in agriculture, requires, in addition to knowledge of the specifics of growing and caring for plants, physical efforts.
It is necessary to be able to loosen the soil, weed plantings, add soil, work with fertilizers, prepare vegetable seeds for sowing. Then sow them with vegetable seeders or manually, lime the soil.
At present, Oleg Ivanovich applies the knowledge accumulated over 43 years of practical activity on his site, which he has been successfully engaged in for more than 10 years.
