Ash as fertilizer – excellent result without cost

smoldering coal Ash is an absolutely affordable and highly effective phosphorus-potassium fertilizer containing a lot of substances and microelements necessary for the development and growth of plants. You do not need to buy it, you do not need to use transport for transportation – such fertilizer can be made on your own. The availability and benefits of ash are undeniable! Although it should be noted that the quality characteristics and the mass fraction of certain microelements may vary depending on the raw material used to obtain the ash.

Important! When using ash as a fertilizer, it should be remembered that nitrogen evaporates during the combustion of raw materials, respectively, its shortage must be compensated for with any nitrogen-containing additives..

        Ash use on different types of soils

        • Agricultural technicians do not recommend using ash as fertilizer on soils with high alkalinity. This is due to the chemical characteristics of ash prepared from any raw material – it additionally alkalizes the soil, which can significantly complicate plant nutrition.
        • Loamy and clayey soils – the addition of only 300–500 g / m² of ash significantly improves the fertility and structure of the soil. Even after a single application of fertilization, the positive effect can last up to 4 years.
        • Acidic soils – when wood ash is applied as fertilizer, a certain balance is created between the natural reaction of the earth (acidic) and an alkaline component (ash), which has a beneficial effect on the growth and development of plants. The exception is crops that initially prefer acidic soil: potatoes, radishes, melons and some others, as a result of which these plants must be fertilized with ashes very carefully, after weighing the possible benefits and probable harm.

        Methods of using ash as fertilizer

        In practice, ash as fertilizer is used in 3 ways:

        1. Dry scattering in tree trunks, under bushes, between rows of garden crops and in holes before planting seedlings.
        2. Spraying or watering plants with a concentrated solution and / or infusion made from plain water and ash.
        3. Laying in a compost heap (2 kg / m³). Subsequently, the compost is used traditionally.
