Is wood ash acidic or alkaline?
This article brings you knowledge about the common sense of flower cultivation, whether wood ash is acidic or alkaline. Let's take a look together.
Wood ash is an alkaline fertilizer that has the ability to neutralize acidic soil. It mainly increases potassium fertilizer. If wood ash is mixed with bean cake fertilizers, it can cause the fat in the bean cakes to separate. Wood ash not only has certain insecticidal properties but also promotes bacterial fermentation and the decomposition of organic matter. If mixed with an appropriate amount of wood ash during composting, it can help the decomposition of organic matter. Wood ash is beneficial for drought resistance and frost damage, so it is a very good fertilizer.
Precautions for the application of wood ash:
1. Wood ash should not be mixed with organic farmyard manure (human waste, livestock manure, compost, etc.) or ammonium nitrogen fertilizers to avoid nitrogen volatilization losses; nor should it be mixed with phosphate fertilizers to avoid phosphorus fixation, which reduces the effectiveness of the phosphate fertilizers.
2. As wood ash is alkaline, it is suitable for application in clayey, acidic, or neutral soils.
3. The potassium in wood ash, more than 90% of which is soluble in water, is a fast-acting potassium fertilizer. Based on this characteristic, wood ash can be used as a foliar spray for root dressing, i.e., using a 1% wood ash extract solution for leaf spraying.
4. Priority crops: Wood ash is suitable for a variety of crops, especially those that prefer potassium or are potassium-loving but chlorine-averse, such as potatoes, sweet potatoes, tobacco, grapes, sunflowers, beets, etc. When used on potatoes, wood ash can not only be applied to the soil but also used to coat the wound of the potato tubers, which can serve as seed fertilizer and prevent wound infection and rot.
The above is [] about whether wood ash is acidic or alkaline, and whether the alkalinity is strong, the experience of green plants and flowers, hoping to bring help to your life!
