What is dolomite flour
This type of fertilizer is obtained by crushing and grinding the natural mineral dolomite in special industrial plants to the smallest fractions. This produces a gray or white powder that resembles flour. For this reason it was called "dolomite flour".
The natural origin of such a powder does not require its enrichment with additional mineral elements. For this reason, flour is classified as a highly environmentally friendly substance, the use of which is safe for human health.
The fertilizer contains 30% calcium oxide and 22% magnesium oxide. They do not accumulate in large quantities in the fruits of plants.
In specialized stores, fertilizer can be sold in bags of 5 kg or 10 kg. Its widespread use is due to its useful properties and a fairly low price, which for many is a significant factor.
Pros and cons of using dolomite flour
The main advantages of using this fertilizer:
- restoration of the normal level of soil acidity;
- improves the structure of the fertile soil layer;
- enrichment of the earth with the necessary chemical elements (potassium, nitrogen, magnesium, calcium, phosphorus), which helps to improve the development of not only the root system, but the entire plant as a whole;
- activation of the vital activity of various microorganisms, contributing to the improvement of the soil and its saturation with oxygen;
- purification of plant elements from radionuclides;
- reducing the number of weeds in the fertilized area;
- destruction of harmful insects by dissolving their chitinous cover;
- increasing the formation of chlorophyll involved in photosynthesis;
- the quality of fruits improves, which is manifested in their ecological purity and the possibility of long-term storage;
- the efficiency of the applied mineral and organic fertilizers increases. This has a beneficial effect on the amount of the harvested crop;
- plants are less susceptible to infections;
- the ability to use in different seasons of the year.
Despite the large list of positive properties, the use of dolomite powder has a number of disadvantages:
- the need for preliminary measurement of soil acidity;
- adherence to the indicated dosage. An excess of the amount of a substance during feeding can cause the death of the plant;
- incompatibility with some types of fertilizers;
- the desired effect occurs after 2-3 months. after feeding, therefore, it is necessary to take into account the time of the procedure;
- this fertilizer is not suitable for some plants.
The disadvantages are insignificant and will not cause difficulties if the rules for the use of dolomite powder are observed.
Such a substance is incompatible with the following types of fertilizers:
- ammonium nitrate;
- ammonium sulfate;
- manure (it is brought in after a few days, reducing the amount by 2 r.)
The listed substances are recommended to be applied 10 days after feeding with dolomite flour.
The use of dolomite flour in the garden, how to sprinkle it correctly
Most garden plants will not grow well if the soil is acidic. Therefore, to create ideal conditions, it is recommended to use a soil deoxidizer such as dolomite flour.
An acidic environment causes the following negative consequences:
- lack of nitrogen. This leads to a slower growth of the planted culture, the death of buds, the presence of small fruits, a decrease in photosynthesis due to a violation of the formation of chlorophyll in the leaves;
- phosphorus starvation is manifested by such signs as insufficient flowering and fruiting or their complete absence, premature leaf fall;
- destruction of the root system due to its defeat by fungal infection and various parasites;
- the biological properties of the soil are reduced.
Experts recommend feeding with dolomite flour when growing the following garden crops:
- cabbage of all kinds;
- greens (parsley, cilantro, dill, lettuce, celery);
- garlic and onions;
Determination of soil acidity index
In order to find out the pH of the soil, it is measured in 4 ways.
An electrical meter or pH tester is purchased at a specialist store. Such devices are easy to use. Stages of the pH measurement procedure:
- take soil from several sites. If the soil is excessively dry, it must be softened with rainwater until a homogeneous mushy mixture is obtained. Then she must stand for a while;
- check if the probe is dirty. For a clean measurement, do not touch it with your hands;
- the probe is placed in the soil completely and after 5-10 minutes. the pH indicator is displayed on the device screen;
- it is recommended to carry out the procedure 2-3 p. and calculate the average.
An additional function of electrical devices is to measure soil temperature. This helps when carrying out spring planting.
The presence of certain plants on the site
If there is a large amount of chamomile, wild plantain, sedge, field horsetail, dandelion, cornflowers, heather, field mint, clover, and wild rosemary in the garden plot, we can talk about the acidic environment of the soil.
Using litmus paper
To carry it out, they take land from the site and mix it with water in a ratio of 1 to 4 until a mushy consistency is obtained. For 2-3 sec. a litmus strip is immersed in the mixture.
After 1 min. its color changes:
- alkaline medium - green or blue;
- slightly acidic soil - pink;
- high acidity of the soil - red.
This method does not require large material costs, but the indicator error differs in several units.
Take 2 tbsp. l. soil and put them in a bottle. Add 5 tablespoons to it. clean water and 1 tsp. chalk powder. A rubber fingertip is pulled over the neck of the bottle, and then they shake it well. Full straightening of the fingertip indicates an excessively acidic soil environment.
Depending on the pH level of the soil, it is recommended to apply the following amount of dolomite powder per 1 m2 of the plot:
- pH <4.5 - from 500 to 600 g;
- pH = 4.5-5.2 - 450-500 g;
- pH = 5.2-5.6 - 350-450 g;
- pH from 6 or more - there is no need for a fertilization procedure with such a substance.
The consistency of the soil should also be taken into account. If the soil is heavy or planting is carried out on alumina and loam, then the amount of fertilizer must be increased by 15%. If there is light soil on the site, it is necessary to reduce the volume of dolomite flour by 1.5 rubles.
Time of feeding
The main advantage of using such a fertilizer is the ability to use it at any time of the year. This ensures high-quality preservation of soil properties, which has a positive effect on productivity.
Consider the ways of using dolomite flour depending on the season
Spreading dolomite flour over the site is carried out 2 weeks before planting. Moreover, it must be distributed in an even layer over the entire territory of the garden.
This contributes to the saturation of the soil with the necessary mineral elements and its reorganization, which helps to protect crops from being damaged by various diseases, as well as from being eaten by all kinds of pests (Colorado potato beetle, bear).
It is considered an ideal period for feeding fruit trees and shrubs. Dolomite flour is scattered around a circle, in the center of which there is a tree trunk (about 2 kg) or a bush (0.5-1 kg), and then the soil is loosened.
In the last days of February, fertilizer is poured onto the snow throughout the site. At the same time, it is necessary that on this day there was no strong wind and frost, and the snow layer did not exceed 30 cm, otherwise the effect of feeding will be reduced to zero.
The use of dolomite powder helps to prevent the negative influence of pests on the development of the plant. In this case, you can use dolomite flour diluted with water as a plant sprayer or apply powder to the soil, observing the correct dosage.
Gardeners use this product before using other fertilizers due to its incompatibility with most types of such substances.
There are several variations:
- scattering dolomite flour over the entire territory of the garden plot, after which the soil is dug up;
- distribution of fertilizer over a certain bed with a rake;
- using a plane cutter, the powder is embedded in the near-trunk circle. After that, it is necessary to mulch the soil;
- before planting seedlings, fall asleep in each hole 5 tbsp. fertilize and mix the soil.
The frequency of top dressing depends on the type of soil.
Clay soil must be processed every year, and 1 r. Is added to light and medium soils. at 3 y.
American vegetable grower Jacob Meatlider has developed his own method of applying this fertilizer, which is ideal for feeding plants in a vegetable garden.
The procedure is carried out as follows:
- dolomite powder (1 kg) is mixed with boric acid (7-8 g);
- the resulting mixture is applied with mineral fertilizers in an even layer;
- carry out plowing.
On heavy soil, the amount of dolomite flour required for the procedure is 200 g per 1 running meter, and on light soil - 100 g.
When fertilizing plants grown in greenhouses, 100 g of dolomite flour must be scattered per 1 square meter over the entire area of the garden, without digging up the soil after top dressing.
At the same time, a film is created on the surface of the earth that retains moisture, which prevents premature drying out of the soil.
Important: before scattering dolomite powder, it is imperative to clarify the acidity level of the soil in order to avoid the death of the planted plants.
You will notice the effect of the feeding procedure only after a few months, when the level of acidity of the soil is normalized, and the maximum result of the introduction of dolomite flour will appear 2-3 years after its use.
How dolomite flour is used for houseplants
This type of fertilizer is widely used by flower growers at home. The main method of introducing dolomite flour into the soil of indoor plants is considered to be the bait method developed by B.M. Macuni.
To prepare a mixture based on dolomite flour, the following components are used:
- superphosphate (1 tablespoon);
- sphagnum moss;
- peat (4 l);
- river sand (1 l);
- charcoal (0.4 l);
- the soil in which the houseplant will be planted (2 l);
- dolomite flour powder (1 tablespoon).
Put all the ingredients in a bucket and mix thoroughly. The resulting mixture is applied to the soil several weeks before planting the flower.
In order for your plants to fully develop and have a high yield, dolomite flour is ideal for feeding garden crops.
You will be able to collect not only a rich, but also an environmentally friendly harvest. Its introduction into the soil of indoor plants will protect them from damage by various diseases, which will have a positive effect on flowering.
Caring for flowers will not cause any special problems, and the house will be filled with natural beauty.
