Wood ash - as a type of vineyard fertilizer (video)
One of the quality types of fertilizer for the vineyard is wood ash. This fertilizer is one of the most affordable. You can cook it at home, adhering to a certain recipe.
Wood ash is common phosphorus-potassium fertilizer, which contains a lot of useful substances: calcium, iron, zinc, magnesium, sulfur. Also, the ash contains trace elements useful for plant development.
In the process of preparing fertilizer from ash, superphosphates, ammonium nitrate, and urea are not added to its composition, since they shorten its effect.
Thanks to the author for a nice video. Yes, wood ash is indeed a very good natural phosphorus-potassium fertilizer that can be obtained naturally without much effort. I also use wood ash to feed grapes, currants, raspberries. In addition, ash is used in the fight against aphids. You can sprinkle it on a diseased plant, or you can spray it with a solution (water and ash).
