Soil acidity - any gardener knows about it. In our latitudes, of course, alkaline soils are found, but basically everyone is faced with soil that has increased acidity. And this must be fought. One of the best ways to normalize acidity is with dolomite flour. What it is and how to use it, we will tell you about this now.
Dolomite has a glassy sheen, and its color ranges from a slight grayish, white, to brown and reddish. It is a mineral with a crystalline structure, of the carbonate class. Dolomite flour is obtained by grinding a mineral to a powder state.
The cost of such a mineral is quite low, and its valuable properties have made dolomite flour very popular among gardeners, summer residents and flower growers, both amateurs and professionals.
Dolomite flour properties
Dolomite flour has found wide application in many areas of agriculture. Because when it is introduced into the soil, its increased acidity is neutralized. But that is not all. Flour enriches the earth with essential trace elements. Magnesium, potassium and many others. Therefore, dolomite flour is the most valuable fertilizer for all crops. Flowers, vegetables, berries, grains, fruit trees, etc.
For flower growers, this fertilizer is simply irreplaceable. It is used outdoors, in greenhouses, at home and dolomite flour shows brilliant results.
How to use dolomite flour
First, you need to measure the acidity of the soil, using litmus paper or others. When you are sure that the soil is acidic, then you just need to use flour.
Dolomite flour is introduced once every three to four years. Depending on the acidity.
- pH less than 4.5 (acidic) - 500-600 grams per 1 sq. m.
- pH 4.5-5.2 average acidity - 450-500 grams per 1 sq. m.
- pH 5.2-5.6 weak acidity - 350-450 grams per 1 sq. m.
- Normal soil acidity values are 5.5-7.5 pH, depending only on the crops that you are going to plant on this soil.
But if the land on your site, garden, greenhouse or greenhouse is neutral, then you do not need to use such flour. Remember that you cannot increase the dosage either, because it can change the acidity of the soil quite dramatically.
If you are going to use flour for liming trees, do it at the rate of 1-2 kilograms per tree. Use every two years. For bushes, reduce the rate by half.
Dolomite flour of extra fine grinding is used for treating plants for controlling insects. This fertilizer not only has unique properties for any plant species, but also has a low price and an unlimited shelf life. Dolomite flour is incompatible with saltpeter, urea, superphosphates, ammonium nitrate.
Use such fertilizer correctly, and it will help you optimize the biological processes of the soil, accelerate photosynthesis, and help get rid of harmful insects...
