The favorite folk fertilizer – wood ash – may not bring any benefit. This can happen if you use the material after burning construction waste.
In addition, there is an opinion that ash from a barbecue is also not the most useful, and all because of the combustion temperature - it contains few useful substances.
But it is also important to know when, with what to add the combustion product and in what quantities.
Dosage
This figure depends on the type of soil and crops grown.
If we talk about the structure of the soil, then ash is added to loose and light soil in the spring before planting, and on heavy soils it is used in the fall.
Fertilizers
Do not use this organic fertilizer together with nitrogen and phosphorus additives. As a result of the chemical reaction, volatile ammonia will be obtained instead of nitrogen, and phosphorus together with ash will be difficult for plants to assimilate.
Storage
In addition, ash that has been exposed to rain or snow, or in a room with high humidity, becomes useless - all the useful substances will be washed out of it.
Deadlines
Ash in its pure form is not added to the holes for planting seedlings - only after mixing it with the soil.
A faster result from adding ash can be obtained if you dissolve it in water (1 glass per 10 liters of warm water).
Gardeners claim that ash is not inferior to mineral fertilizers in its properties. Its only difference is its duration of action.
The effect of ash will take longer to appear than that of industrial additives. Therefore, natural fertilizer is often added to the soil when preparing beds in the fall.
