Negative lime for what is used. What is lime, its characteristic. Plants Soil Acid Indicators
Lime hawed (Other names: calcium hydroxide, lime hated meat, lime hydrate hawed) is obtained by interacting with water and calcium oxide (oversized lime). Negregated lime - coming or ground poured with water. Different mixtures can be obtained from the ratio of the amount of water and oversized lime. If water is 60-80% of the amount of lime - we get a flush, by further dilution with water, it turns out limestone dough and lime milk, respectively.
Lime slowly degrades, and its effect can continue from 3 to 4 years, depending on the quantity that was applied, and the soil type. Before adding this amendment, always refer to the analyzing of the soil. Lime can be used approximately at any time of the year, but the most suitable period - from August to October. In the sandy soils it is better to use it in the spring. It should be noted that it is necessary to wait at least a month before spreading fertilizer on the ground, which was lime.
Lime must be included in the first 10-15 centimeters of the soil. If the use of a large amount of lime is required or if the pH value must be changed by several units, the dose should be divided to avoid excessive oscillations. The best wood ash for improving the soil comes from the burning of solid wood. These ashes are the most rich minerals. They provide a significant amount of calcium, potassium, phosphorus and several trace elements. Avoid using painted or treated wood ash, colored paper or plastics, as they contain toxic products.
The process of obtaining hated lime (dehydration)
The dehydration process occurs on open areas or in special creatorials (wooden box, or just a pit). The vection rate can be different, in connection with this, there are views and has the lime hated characteristics as follows:
- fasting lime (about 8 minutes),
- middle (about 25 minutes)
- slow-on (over 25 minutes).
The process itself is accompanied by heat release, so as not to reduce the temperature, water should be added gradually. In the fresh lime can contain the remains of the feedstock, they are reused, ultimately dispose of.
Wood ash has a high alkaline ability due to the high calcium content. They act quickly on the ground, but their effect is short-lived. Wooden ash should be included in the soil or compost in the spring. They should not be used for soils of acidophilic plants and seedlings.
Attention! Wood ash is very soluble and salted. The excess amount of salt in the soil hinders the growth of plants and often causes the death of microorganisms. The reuse of large quantities of ash can also lead to the accumulation of toxic elements in the soil and damage to the assimilation of minerals by plants, so it is recommended to use this amendment in moderate quantities.
The density of the obtained harated lime can be adjusted by the addition of water by mixing. Stop adding water when the latter stops absorbed with solution.
The number directly depends on the quality of primary raw materials. The higher the quality, the exit is greater. So from 1 kg of raw materials of the first grade, you can get more than 2 kg of a limestone test, the output will be less from a second-rate raw material.
The sulfur used as amendment may be in the form of a powder or granules. Sulfur acts on the ground in the medium and long term, therefore it is preferable to apply it in one or two years before landing. In the case of already planted plants, it is enough to distribute the recommended amount on the ground at the limit of the branches and include it in the first centimeters.
Sulfur can be used in spring or autumn in accordance with the results of the soil analysis. If you need to use a large amount of product, it is preferable to execute two applications: the first early spring and second in the fall. Granulated sulfur acts slower than powder sulfur, but its action is more durable. It is also easier to apply less underwear and less dust. Inhalation of sulfur dust can cause irritation of the respiratory tract.
Storage of hawed news
The solution is placed in a special pit, the twenty-hectime layer of fine-grained sand is superimposed on top. In the cold season, to avoid the freezing of the solution, additionally places an earthen layer (approximately 70 cm). The place of storage is struck by special tags and is maintained until the smallest particles rushes. The ingress of outstanding grains into solutions is unacceptable, as they can provoke the swelling of the coating.
Iron sulfate is especially useful for rapidly reduce pH, especially when plants show symptoms of iron deficiency. The amount applied is determined by the analysis of the soil. Its effect on the soil is less durable than sulfur. Aluminum sulfate also reduces the pH of the soil. Ideally, this amendment should be used only with blue hydrangeas, because aluminum has a phytotoxic effect into several plants. Product that will be applied.
Pre-inflated thermal plaster in the recycled glass of foamed glass, available in the version based on cement and natural hydraulic lime. Thanks to the characteristics of the unit and the specific formulation, it provides excellent fire resistance in the section.
Depending on the further use of harees, the exposure time depends. For use in solutions and mixtures for laying enough two-week excerpts, and for use in building solutions for plastering - excerpt should be at least a month.
Application
The area of \u200b\u200buse of hareed lime is quite extensive. It is used in the manufacture of fertilizers, to mitigate water, lime harated for blissing and even in dentistry. But as an excellent binding material, the lime was widely used in construction. Haired lime or limestone dough is widely used as an additive into the building mixtures, as it has properties that can fight fungus and mold, and is also an excellent means of protection against pests (rodents and insects).
- Thermal plaster for insulation of brickwork.
- Breathable plaster.
- Stuccoings with a drain function.
- Application inside and outside, on walls and ceiling.
The roots of cucumbers absorb the ions of these elements in large quantities, which leads to their accumulation in plants increases. It was found that deformed cucumbers are obtained when the plants are grown on the strongly acidic soils. The content of manganese, copper and zinc in cucumber is much larger than in straight fruits grown on less acidic soils. High concentrations of copper, especially zinc, prevent the mechanism of axins synthesis in plants. Auxins are phytogorms that are responsible for the growth of the fetus.
Unlike the oversized lime (boiler), hated lime in the dough has a very long term storage, and the longer stored, the better the performance becomes better.
Almost everyone construction solutions Produced on the basis of sand and water with the addition of various additional components. Lime solutions are prepared in the same way, only with the addition of hazed lime.
The deficiency of calcium and magnesium and the cations of toxic excess aluminum, manganese, copper and zinc ions leads to the disharmony of metabolic processes in the plant. As a result, the flow asymmetric from the leaves to the fetus is also disturbed. The high-quality soil reaction, which adversely affects the growth and development of the plant, is regulated by lime. This uses limestone, limestone, lime, etc.
To limit cucumber distortion, it is necessary to analyze the agrochemical soil, and then give recommendations for lime. The required amount of lime is about 750 g, or 5 kg of lime, and depends on its quality. Blue stone dissolves in 80 liters of water. Varuta dissolves in 10 liters of water. The resulting lime milk is poured into a thin flow into a syneeroid solution with constant and intense stirring. The smaller the resulting suspension, the better the burgundy solution has greater coverage and, therefore, the best fungicidal properties.
The process of preparing a lime solution is simple - water is added and the sample sand is gradually introduced with constant stirring. The resulting solution is preferably skipped through a sieve to select foreign fractions and for greater homogeneity. Due to the fact that a clean lime solution is hardening for a long time, plaster or cement add to it.
Bordeaux solution is used at the following concentrations and diseases
The solution prepared a few hours before treatment should be used. Soil disinfects 3-4 weeks before sowing. For semi-adamping of wheat against the oil head, 2% solution is prepared and 4 liters are used per 100 kg of seeds. Spraying apples and pears with burgundy solution is carried out at the time of the embryos, repeated after falling colors and when the fruits achieve the size of the nut. Vines are sprayed with a burgundy solution when mana comes, and potatoes - when the first spots of manna appear.
Lime is widely used since ancient times, currently solutions with lime are widely used in the construction of agricultural buildings, when building country houses, and just as a whitewash. This is due to the lowest solution.
Spraying by burgundy crop fruit crops ends in 2-3 weeks before harvesting. Agro-pharmacies sell comfortable cuts from blue stone and lime, which you only need to mix and approach gardening in the yard. website. She is still very common with lime. Currently, efficient quartz substitutes are available, which provide good results and justify the expectations of dyeing. IN construction companies Today, mostly young specialists, but often the team has the masters of the so-called. old school.
Most of them are supporters of lime paintings, which two or three decades ago were extremely widespread and widely used. One of the most serious shortcomings of this dyeing technology is a complex and long-term preparation of the decision. Burning causes pollution ambientwhich can not jeopardize human health. It completely replaces the usual lime lime in the minimum amount of cement and sand solution. Cement in this case acts as a binder.
Few people know that the word "lime" combines the general thermal firing products of limestone and other carbonate rocks. This term includes, both having lime, and an overtime lime. Also, the lime varies on chemical composition: Lime construction air, consisting of calcium and magnesium oxides, and lime hydrate, the composition of which silicon, iron and aluminum compositions. Among the builders, lime differences as a combine and powdered. Powdered lime is divided into ground smooth lime and lime hated "Pushonka", which is produced by cleaning calcium, magnesia and dolomitic lime by limited amount of water. There is also there bleaching powder And Natrow.
And the last but no less important: price factor is affordable and inexpensive. Lime-paint is applied for many years and by definition is one of the main technologies in the field of construction and repair work. Among the most ancient and still used binders - lime lime, which is mainly used for masonry and plaster. This uses lime and sandy solutionsAnd they add cement for greater strength. Varta is also added to cement and sand solutions to improve their plasticity.
The sale of hawed (hydrate) and oversized lime is very common, as the lime applies in many industries, but especially in construction. It is used for plastering and masonry solutions, in production. silicate brick and silicate concrete, as well as in the production of dry construction mixes (Puttail, plasters, thread).
For the same purpose, this material is also added to the mosaic stones and cement solutions during plaster. Lime lime is formed by extinguishing lime water. It is produced by burning limestone in the furnaces. This process requires not only a large amount of resources and energy, but also leads to severe environmental pollution. The exhaust lime is obtained after a long aging when removing until the smallest particles go out.
When the lime is painted one of the most time-consuming and tedious operations is the mixing of lime solutions on a limestone site. For this reason, hydrated lime is often used. This is a lime that was powder. In this case, it is necessary to leave the solution again for at least one or two days to quenit large particles. The classic technology of plastering and masonry with a lime solution has a very significant drawback. Old school masters know that a new painted house should not be populated within six or twelve months depending on the air temperature.
Another scope of application of hydrate lime is agriculture. It is used to lime soil and disinfecting livestock farms. Large lime volumes consume ferrous metallurgy, chemical, sugar and pulp and paper industries. If you want to buy a negared lime, then you need to be confident in its quality.
This time is necessary for drying building construction, as well as to enter humidity in healthy limits. However, some of this moisture is due to the chemical process of carbonization of lime under the influence of carbon dioxide in the air. Many believe that water from which the lime solution is produced is responsible for increased air humidity. Thus, it gradually turns into calcium carbonate, and the solution solidifies and connects the brick wall.

Lime: Material is obtained by annealing sediment mountain breeds (limestone, chalk, dolomite) with very high temperatures in mines or furnaces. Under the influence of chemical reaction calcium carbonate loses with carbon dioxide up to 45% of their mass, and becomes porous and easy. Thus, they receive a compete lime. Next, the lime is subjected to quenching with water or additional grinding.
This is reflected in reducing the reaction. In addition, a person by systematic fertilization, especially nitrogen fertilizers, uses various agrotechnical treatments, as well as industrial activities, contributes to an increase in the rate of soil acidification processes. In response to the problem of farmers to optimize the pH of the soil, it offers magnesium carbon magnesium fertilized lime.
Physical and chemical parameters of lime fertilizer
Carbonate fertilizer due to its low solubility can increase pH even a few years after its use, which largely depends on the granulation of soil and humidity. Previously, it could be found on each construction site - the children's zone with a sticky surface, where a slicing white substance was visible. Today, smoking lemon is going on - what is it and what can we extract from it?
Benefits
Powder lime has an advantage over comob: when watering with water, it behaves like gypsum -like forms a plastic dough, and after 30 minutes it grips. A part of the water that forms the dough is leaving the lime quenching, with this dough thick and loses plasticity.
Due to the smaller amount of free water, materials based on powdered lime less porous and more durable. Lime during the junction is heated and it makes it easier to work with it in the cold time.
The most important indicators of the negro powder lime:
Activity - the content of oxides capable of quenching
The number of non-dried grains (fault or nonsense)
Time of quenching (fast up to 8 min, average up to 25 min, slow more than 25 minutes).
