Which fertilizers are best not to mix with others: a brief reminder for the amateur gardener
Modern stores offer gardeners a wide range of fertilizers to choose from – dry, liquid, mineral, granulated, etc.
At the same time, gardeners can get advice on how to use these additives in practice. But buyers rely on instructions.
It should not be forgotten that there are incompatible fertilizers that form an insoluble sediment, have a negative effect on each other, and are antagonists.
Here are the fertilizers that you shouldn't mix and that you shouldn't let others use on your property.
There is no point in adding potassium and phosphorus to alkaline soil. They will remain unavailable to plants.
Ammonium sulfate, ammonium nitrate, ammonium chloride and ammophoska cannot be mixed with ash, lime and dolomite.
Calcium nitrate is not mixed with fertilizers containing phosphorus or sulfur.
Simple superphosphate is not mixed with urea (carbamide) and ammonium nitrate, as this will render both preparations useless.
Sodium nitrate and potassium nitrate are mixed with superphosphate, but only before application.
The same is done with urea, which is planned to be mixed with superphosphate, ammonium sulfate or manure.
When mixing organic additives, wood ash and mineral fertilizers in holes for planting seedlings or saplings, take the trouble to add a layer of soil before adding each one, only in this case will they be useful for the soil and the planted crop.
