It enriches the soil with nutrients and increases yield without unnecessary expenses.
Composition and Benefits of Ash for Soil
The primary component of ash is potassium, which strengthens plants and enhances their resilience to adverse conditions. Additionally, it contains calcium, phosphorus, magnesium, and other trace elements that are essential for crop growth. An important advantage of ash is the absence of chlorine, making it safe for crops such as potatoes, tomatoes, and grapes.
Applying ash in winter allows beneficial elements to gradually permeate the soil along with melting snow, creating optimal conditions for the root systems of future plants. Ash also lowers soil acidity and improves its structure, positively influencing plant development.
How to Properly Apply Ash in Winter
Using ash in winter requires adherence to specific guidelines:
-
Even distribution. Ash should be spread evenly across the soil surface to avoid over-saturation of certain areas.
-
Dosing. For light sandy soils, it is recommended to use 100–150 grams of ash per square meter, while for clay soils, up to 200 grams.
-
Avoid contact with ammonium fertilizers. Mixing ash with such fertilizers leads to nitrogen loss.
-
Thin layer on snow. It is best to apply ash on a snow cover in a thin layer. This allows the substances to gradually mix with water as the snow melts, preventing wash-off.
Crops That Respond Positively to Ash
Ash is particularly beneficial for plants that require higher levels of potassium and calcium:
-
Fruit trees and shrubs. Apple trees, currants, and raspberries develop noticeably better after winter ash application.
-
Vegetable crops. Potatoes, carrots, onions, and garlic respond positively to ash fertilization, strengthening roots, increasing disease resistance, and accelerating fruit ripening.
However, ash should not be used for plants that prefer acidic soil, such as blueberries and rhododendrons.
