Superphosphate is one of the most common mineral fertilizers.
It is difficult to find a summer resident who has never added this product to the soil.
Despite the enormous popularity of the fertilizer, many gardeners are not aware of all the rules for its use.
Very often, gross mistakes are made, which were described by the expert of the online publication "BelNovosti", scientist-agronomist and landscape designer Anastasia Kovrizhnykh .
Reluctance to use protective equipment
Losing the harvest and ruining the soil is not the worst thing.
The most negative consequence may be the emergence of health problems for the summer resident.
A gardener who uses superphosphate on his plot must use protective equipment, otherwise serious consequences may occur.
Don't forget to wear a respirator, safety glasses and rubber gloves.
Incorrect dosage calculation
Both excess and deficiency of superphosphate can harm plants.
Half a kilo of the product is enough for 100 m2 (or approximately 250 grams if we are talking about double superphosphate).
You should put a maximum of half a teaspoon of fertilizer in each hole.
Surface application
Some summer residents simply sprinkle the product on the soil and think that this is enough.
But the effect of using superphosphate will only be if the product is at a depth of at least 0.1 m.
Combination with nitrogen
Superphosphate does not get along with nitrogen fertilizers.
When applied together with nitrogen, the phosphorus source simply loses its effectiveness.
Application on acidic soils
Superphosphate also becomes ineffective if the soil pH is significantly below 7.
Earlier, summer residents were told how to save cucumbers from powdery mildew.
