What is the best substrate for strawberries?

For the amazing taste of strawberries, rich in vitamins and mineral elements, many gardeners devote considerable areas to growing this crop. The most important condition for increasing productivity is the creation of optimal conditions. One of them is a high-quality substrate for strawberries.
The ideal substrate is a mixture of turf soil, peat, humus, fine sawdust and sand. Before using the soil, it is advisable to remove all excess (stones, roots and other large impurities) from it.
Medium loamy turf soil is the best, as it is not acidic and contains quite a lot of organic matter. But it is not used in its pure form, adding sawdust for looseness and lightness. To prepare a substrate for strawberries, take 2 parts of sawdust for 7 parts of soil.
Peat is the purest substrate, lightweight, with excellent water-holding capacity. Experts advise adding a glass of wood ash or 2-3 tablespoons of dolomite flour to 1 bucket of peat, mixing thoroughly.
The most fertile part of the substrate mixture, rich in organic matter, is humus soil. It is obtained from the decomposition of manure and other organic residues.
Sand is added to soil mixtures for strawberries in small quantities - no more than a tenth of the total volume of the entire mixture. River, coarse-grained sand is best suited for these purposes.
These components in the composition of the substrate for growing strawberries is one of the possible options. But it has been well tested by many years of experience.
