Precipitate (calcium hydrogen phosphate) is a concentrated phosphate fertilizer used for preliminary soil enrichment before planting or sowing crops, as a mineral supplement added to pet food. What kind of fertilizer is this, what does the precipitate formula look like, and how to apply the phosphate fertilizer precipitate, read on.
How to recognize precipitate in the market
Externally, calcium hydrogen phosphate is white-black in color, powdery with inclusions of finely ground granules. Does not cake and does not dissolve in water. Therefore, the solubility of the precipitate in water is a question that most often interests gardeners and gardeners.
He looks like fluffy powder. As a rule, there are no difficulties during the application of fertilizer, but it is recommended to pay attention to some features:
- substance does not dissolve in water;
- in combination with other mineral supplements, the fertilizer actsmore active.
Today, the market is overflowing with a variety of fluorine-containing fertilizers: superphosphates, phosphate rock, tomasslag. But the precipitate is the most effective and one of the very first fertilizers containing phosphorus.
Formula and composition of the substance
The formula of the precipitate is as follows: CaHPO4·2H2O - dikaliyium phosphate dihydrate. This mineral-based chemical composition is obtained as a result of the combination of phosphoric acid and limestone or chalk, which react with each other. The acid is neutralized by maintaining the temperature during the reaction at around 50o. The fluorine content in the composition is 50%.
The composition of the fertilizer is suitable for use on podzolic soils. Actively affects the acidity of the soil, helping to reduce it.
Why is it recommended to use mineral phosphate fertilizers in agriculture
To grow a good harvest, you have to work hard. For this purpose, as well as to stimulate the growth and flowering of plants, agronomists recommend applying fertilizers, for example, phosphorus, during the growing process. Precipitate is a bright representative of this group of dressings. It is actively used both as an independent fertilizer and as a component of other complexes.
Fertilizer, whatever it may be, is responsible for the he althy active cultivation of plants, obtaining a crop of the highest quality. Recently, not onlyorganic compounds, but also mineral complexes that are enriched with chemical elements. The element indispensable in the composition of the precipitate is phosphorus, which is responsible for fertility.
How do phosphate fertilizers affect plants
So, using precipitate as a top dressing for your crops, you can count on solving the following problems:
- increasing yield levels;
- plant resistance to various immune diseases;
- improving the quality characteristics of fruits, including keeping quality;
- emphasis on improving sensory ratios.
Precipitate is a fertilizer that can actually be applied to any soil. Although the reaction occurs best on podzolic soils, as they are more prone to oxidation than others.
A distinctive feature of the powder that does not dissolve in water is the rapid decomposition into individual components in an acidic environment, which allows saturating the soil with phosphorus even faster. This effect is more pronounced when fertilizing young cultivated plants, the root system of which has not yet been fully formed. It is phosphorus that makes it stronger and stronger. And he is also responsible for increasing the level of sugar in fruits, which directly affects the taste of the future harvest.
Another feature of the precipitate as a fertilizer is to promote the uptake by plants of poorly soluble s alts contained in hard rock soils.
What is the principle of phosphate fertilizer
Operating principleprecipitate - phosphorus fertilizer and mineral fertilizer for vegetable and horticultural crops, as well as feed for large pets, in its scheme resembles the principle of operation of any other composition based on phosphorus. The only difference is the duration of the process, which is longer for calcium hydrogen phosphate (precipitate). What can not be said about superphosphate, which decomposes many times faster in an acidic environment. Based on this, it is not difficult to imagine how quickly weakened plants will be saturated with all the nutrients necessary for he althy growth and development.
Among the features of calcium hydrogen phosphate is another important quality - the precipitate is a composition that is harmless to both the soil and the plant compared to other top dressings containing phosphorus. This is explained banally - the minimum content of chemistry.
How to understand that a plant needs to be fed
Among the main signs that a plant needs to be fertilized with precipitate are the following factors:
- bottom leaves of the plant have turned purple with a purple tint, instead of a he althy dark green;
- changed leaf structure;
- plant growth slowed down or stopped altogether;
- insufficient nutrition of the aerial part of the plant due to weakening of the root system.
As you already understood, the precipitate is an indispensable fertilizer in agriculture, constitutinghe althy competition with other formulations due to its safety and effectiveness. It will be a great help for the gardener. We hope the information provided will help both a beginner and an experienced gardener in choosing fertilizer for their garden or vegetable garden.
