Superphosphate fertilizer: instructions for use in the garden

Double superphosphate allows you to enrich the soil not only with the necessary amount of phosphorus, but also with other nutrients. Due to the constituent components, the yield increases and the immunity of the culture is strengthened. You can buy the drug at a low price in granules or in powder form, so the fertilizer is popular.

Useful properties of the product

Superphosphate fertilizer is a balanced complex of nutrients necessary for the normal development of any crop in the garden or garden.In addition to phosphorus, the composition of the fertilizer includes various other trace elements. They feed fruit trees, vegetables, berries, flower beds.

Why do plants need a balanced complex of substances? It is needed in order to slow down the aging process, to develop a strong and he althy root system, including tubers, to accelerate the process of fruit formation and ripening.

Differences between fertilizer with twice the amount of the main component and conventional top dressing are the absence of calcium sulfate impurities and the content of other important elements. Why feed? Dual fertilization has a number of advantages:

• does not contain extra fasteners;
• stimulates plant growth well;
• nitrogen has a beneficial effect on the increase in the number of ovaries;
• sulfur increases strength and immunity;
• pellets do not deteriorate, which is convenient for long-term storage.

The main application of the diluted fertilizer takes place in the spring and at the end of September. With surface application, it is necessary to dig up the soil. When planting a vegetable crop, simply granules are used, which are laid out in holes.

Advice: so that the selected type of composition brings only benefits, dilute all components strictly according to the instructions. Each vegetable crop at a different stage of development needs certain amounts of a particular microelement.

There is a wide variety of fertilizers, which include the presented complex. To study the difference between them, a description of the most basic compositions is presented.

Varieties of compositions

There are several types of superphosphate fertilizer, which differ in composition. To replace one type of fertilizer with another, you need to know the composition and quality of the soil and take into account the characteristics of plant development.

The composition of simple superphosphate contains no more than 20% of phosphorus oxide, which is needed for potatoes, carrots, and beets. It was noticed that vegetable crops after the applied fertilizer differed in appearance and tasty fruits. The plant developed faster, hurt less, looked more powerful than others and gave a high yield.

The usual composition is best used as an additive to compost, since fertilizers do not dissolve well in water. Vegetable components alternate with product granules in a large container or compost pit. The prepared mixture can be used next year.

The main difference between double superphosphate and a simple composition is the content of active substances, there are much more of them. Double superphosphate is available in the form of small gray granules that quickly dissolve in liquid. It is recommended to apply it during tillage in April and September.

Traditionally, fertilizer with a granular composition is used. It can be applied dry or used to prepare a liquid solution. Superphosphate granular contains a high percentage of phosphorus. Superphosphate also contains more than 30% calcium sulfate. Well stored and distributed when applied to the ground. It is desirable that the soil is not acidic, otherwise there is a need to add wood ash.

Superphosphate ammoniated includes a large percentage of sulfur and potassium sulfate, has good solubility in water and does not change the acidity of the soil. Superphosphate double ammoniated is a concentrated fertilizer of nitrogen, calcium and phosphorus.

Humatized composition is distinguished by an additional component in the form of peat humate (potassium or sodium).The composition contains 20% phosphorus, about 3% are humates. After getting into the soil, it is well absorbed by the plant. The use of this type of fertilizer helps to strengthen the roots and the formation of large fruits. Humate improves disease resistance, yields and reduces nitrate.

How to dissolve superphosphate in water

Phosphorus fertilizers are difficult to dissolve in water, and there is little benefit in the dry composition. But in liquid form, they quickly penetrate from the soil into the plant. Superphosphate extract is easy to prepare. In the process, the granules are crushed, but not completely decomposed.

During the preparation of formulations, it should be borne in mind that superphosphate is remarkably combined with potassium preparations. These two components help each other to be better absorbed by the plant.

Extract from superphosphate is done by dissolving the granules with boiling water. The following proportion must be observed: 100 g of granules are required for 1 liter of water.Hot water does not reduce the beneficial properties of the fertilizer. On the contrary, it becomes easily digestible and quickly penetrates into the vegetable crop. The solution is moved to a warm room and left to infuse for a day. It needs to be stirred periodically. After that, the solution is filtered so that there is no sediment.

How to prepare a nutritious top dressing? The following recipe is effective and popular. A solution of superphosphate is preliminarily made: 65 g of fertilizer is dissolved in three liters of boiling water. After that, the working composition is prepared. In a bucket of water, you need to dilute all the components: 150 g of the resulting solution, 450 ml of wood ash and 25 g of nitrogen. Nitrogen is added for good and fast absorption of phosphorus.

Using a fertilizer with natural organic ingredients is an efficient and cheap way to feed your plants. 150 fertilizer granules are poured into a bucket of raw manure, mixed thoroughly and left to infuse for two weeks.

Another method of how to dissolve superphosphate involves mixing with various biobacterial solutions, such as "Fitosporin" or "Humate". The mixture is poured with hot water and left to infuse for 22-24 hours. Only after this time you can use the solution.

Processing potato beds

Instructions for use involves fertilizing in early spring and autumn after harvest. In fertile soil, it is enough to add 45 g of superphosphate per 1 sq. meter. For depleted lands, the amount is increased to 65 years.

For potatoes, phosphorus is an integral element, so when growing it, the use of superphosphate is mandatory. There are several ways to apply fertilizer. You can fertilize the soil when preparing it in the fall, while it is recommended to prepare a solution of superphosphate (35 g), fresh manure (7 kg) and potassium sulfate (18 g).

For potatoes, a solution is most often prepared for foliar processing and watering. It is recommended to add superphosphate to slow down the development of tops and prevent its rapid aging. At the same time, nutrients penetrate into the tubers, their growth, maturation is accelerated and the amount of starch increases.Potatoes are stored for a long time, do not deteriorate. It is best to process a vegetable crop three weeks before harvest.

During the spring digging of land in the garden, it will take 1 square. meter take 35 g of superphosphate, 18 g of ammonium nitrate and the same amount of potassium sulfate, 450 g of dolomite flour.

Double superphosphate is used for top dressing during planting. 150 g of manure, 45 g of ash and 6 g of superphosphate are distributed into each hole 10 cm deep. Prepared seed material is thrown on top of the fertilizer.

Top dressing with superphosphate is also carried out if it was noticed that the leaves have darkened, wither and fall off. For seedlings, you need to take double superphosphate in the amount of 4 g. The drug is dissolved in a liter of water. It is recommended to spray each bush.

Before flowering potatoes with superphosphate, it is useful to carry out foliar spraying. There is nothing complicated about how to make fertilizer. Dilute 2 g of ammonium nitrate and potassium chloride, 20 g of superphosphate and 0.1 g of copper sulfate. Pour all the components with water and leave to infuse for 4 hours. Before spraying, the resulting solution is diluted with water in a ratio of 1: 1. Treatment should be carried out in the evening.
