Many people make a serious mistake if they consider ash to be a universal fertilizer.
Yes, this type of fertilizer has a lot of advantages due to its excellent composition, but it also has its disadvantages.
For example, not everyone knows that ash is not compatible with all fertilizers.
What should not be mixed with ash?
Organics
This fact will surprise many, but ash is absolutely incompatible with some organic fertilizers. These include humus, chicken manure and fresh manure.
It is recommended to maintain a long pause (up to a month) between the introduction of these compositions.
Sources of nitrogen
If you are adding nitrogen sources, you should avoid adding ash. Therefore, do not use fertilizer when using urea or ammonium nitrate.
Other nuances
You should not add ash if you decide to use any phosphorus-based compositions. Ash will also not "make friends" with dolomite flour: you need to choose one of the two products.
No negative reactions were observed with any other fertilizers.
