A cheap natural fertilizer made from dolomite helps not only to normalize acidity, but also to significantly improve the condition of the soil and increase yields. Sold in the form of a carbonate powder called limestone / dolomite chips, marked as a soil deoxidizer. We bring to your attention a list of useful properties of dolomite flour
Increased fertility
When small fractions of dolomite are introduced into the soil, saturation with potassium, phosphorus, magnesium, and nitrogen occurs. The structure of the surface layer of the soil is being improved, and fertility is increasing.
Flour suppresses fungi, mold, activates the development of microorganisms. Promotes an increase in the population of annelids, which makes the soil viable. In addition, the growth of many types of weeds is reduced (dandelion, wheatgrass, coltsfoot, plantain, wood lice, clover, buttercup).
Experienced vegetable growers, in the beds with cucumbers, tomatoes, cabbage, use dolomite together with boric acid (7-8 g per kilogram of flour). The powder is scattered over the bed and dug up. For heavy and alumina areas take 200 g per square meter, for light - 100 g. The frequency of application is every 3-4 years.
Neutralizing acidity
To determine the state of acidity, a litmus plate is used or analysis is done using a commercially available analog or digital tester. You can determine the increased acidity and by eye. A clear sign is the growth of horsetail, wild violet, sorrel, cornflower, poisonous buttercup, fern. In these cases, before planting vegetables or other crops, you need to deacidify the earth - add dolomite flour.
If you have a Ph-meter and you have learned the exact state of acidity, then dolomite flour is used as follows: for weakly acidic soil, add 350-450 g / m2, medium acid - 450-500, acidic - 500-600. In alkaline and neutral - do not add.
Improving fertilizer efficiency
It is known that the acid in the soil prevents plants from fully assimilating phosphorus. By deoxidizing the soil, you remove the obstacle in nutrition, your plants begin to develop well and bear fruit.
It is important to know the rules for adding dolomite flour. With an illiterate combination with fertilizers, a negative reaction occurs - their benefits are neutralized. Dolomite flour must not be added at the same time as superphosphate, compost, ammonium sulfate, manure, ammonium nitrate. First apply dolomite and after 7-10 days other substances.
Increased yield
Dolomite flour accelerates the growth and proper development of fruits, it neutralizes heavy metals, harmful substances / radionuclides in the ground and prevents their accumulation in fruits. Leafy greens are more active in gaining mass.
Calcium and magnesium, which are found in abundance in dolomite, stimulate the growth of all parts of plants, including the roots. This fact contributes not only to fruit formation, but also improves the quality, for example, the amount of protein in potatoes increases.
Lack of aggression
By eliminating the increased acidity with slaked lime, you get an aggressive reaction that is not always favorable for plants, which leads to a slowdown in the absorption of phosphorus. Therefore, liming is carried out only in the fall.
As for dolomite flour, there are no restrictions on the introduction - you can safely use it throughout the year. Experienced gardeners use winter application: they are scattered over the snow, after thawing it perfectly gets into the soil and fertilizes, reduces acidity. The event is held in calm weather, with a snow thickness of no more than 30 cm.
Fertilizer for the garden
Dolomite flour is used when planting a seedling. 500 g is added to the hole under the stone tree (plum, apricot, cherry), 300 g to the pome tree (apple tree, pear), and 100 g to the fruit bush. … An adult tree takes 2 kg, but a fruit bush is 0.5-0.7 kg.
The benefits of dolomite flour are obvious: harvests increase, plants are fed with magnesium, which is part of the composition, it stimulates the formation of chlorophyll, and improves photosynthesis. As a result, the plants become strong, the foliage acquires a rich green color.
Pest control
Fine grinding of flour, falling on the body of the larvae and chitinous shells of insects, leads to their death. By adding dolomite flour, you simultaneously fight wireworms, garden bugs, ticks, aphids, butterflies. The population of the Colorado potato beetle, the bear is declining. Planting processing takes place at intervals of 4-6 weeks.
To combat pests in the garden, limestone flour is sprinkled on the trunk circle, leaves, trunks, branches. By the way, dolomite is harmless for pets.

The Benefits And Harms Of Rosemary
Rosemary is a truly unique plant that deserves the closest attention, because it is considered both an excellent spice and one of the most powerful and effective medicinal herbs. This attractive herb is successfully used in cooking, and in folk medicine, and even in cosmetology! Nevertheless, despite the huge number of useful properties, not everyone can use rosemary. So who will it do a good job, and who better to abandon the idea of using it?
Dolomite Flour To Help The Summer Resident
Summer residents with solid experience are well aware that the yield of crops grown on the site is approximately 80% determined by the physicochemical characteristics of the soil. And here such an important and valuable product as dolomite flour comes to the aid of many gardeners and gardeners - the components that make up this environmentally friendly fertilizer will actively contribute to the formation of not only a strong and healthy root system, but also well-developed tubers with root crops.
