A lot of organic waste accumulates on any site. These are cut tree branches left over from cucumbers, tomatoes and other top plants, raspberry shoots, blackberries, old boards and other wooden products.
Everything goes well with a skillful owner. Some people put all the organic matter on the compost heap, but there is another way to turn garbage into valuable fertilizer - to burn it.
Ashes in the backyard are worth their weight in gold
Ash is a unique natural fertilizer. It contains phosphorus and potassium, which depend on both the intensity of fruiting and the quality of the fruits. With a lack of potassium, vegetables, fruits and berries do not pour well, accumulate little sugar, which negatively affects the taste.
Ash also contains a lot of calcium (up to 30%), which is an important element involved in cell fusion. With a lack of calcium, the leaves turn yellow, become vulnerable to diseases and pests, and top rot appears on the fruits.
In addition, ash is a full-fledged replacement for complex fertilizers with macro- and microelements, since it contains most of Mendeleev's table. Boron, magnesium, manganese, iodine, molybdenum, iron and other components necessary for plants enter the soil with ash.
Why does ash have such a rich composition
Plants consume all the substances mentioned above and accumulate them in leaves, stems, and roots. When burned, these substances remain in the ash in high concentration. Their percentage ratio varies depending on the burned material, so the more diverse the remains that are burned, the more useful the ash will be.
The most nutrients are in deciduous trees. The rich composition has the remains of tomatoes, cucumbers, zucchini, sunflower stalks, and straw. In general, any plant contributes to the composition of ash.
Old boards and other old wood are less useful, but also contain useful substances.
What cannot be used for burning
Do not burn inorganic materials in the bonfire, such as plastic, wood covered with varnishes and paints, synthetic fabrics. They will litter the earth with microplastic particles and harmful compounds.
Everything that was in the burnt mass remains in the ashes. Do not forget about heavy metals (lead, tin, mercury). It is not recommended to use plants that grew along the roads, in an industrial zone or within the city limits for the preparation of ashes.
What else you need to know about "gray gold"
Ash has an alkaline reaction. It is an excellent soil deoxidizer, especially fresh. It can be applied dry for digging or diluted in water.
If the soil is alkaline, then the deoxidation function can be eliminated by quenching with acid. In this case, acid is added to the aqueous ash solution. The simplest recipe: 10 liters of water, 1 tbsp. ash, 1 tbsp. 9% vinegar.
