Scab is a serious disease that deprives gardeners of a significant part of their potato harvest.
Those tubers that do manage to be collected do not have a long shelf life and do not have the most intense taste.
Therefore, the gardener must do everything to ensure that the dangerous bacterial disease does not affect the popular crop.
It is necessary to follow three important rules, which were reminded by the expert of the online publication "BelNovosti", scientist-agronomist and landscape designer Anastasia Kovrizhnykh .
Potatoes should not be planted in a plot with alkaline soil. It is also desirable that the soil is not light and sandy.
It is also important to remember the need to observe crop rotation: the ideal place for a garden crop will be a plot where legumes were grown last season.
The risk of scab will be reduced by adding superphosphate.
Excess potassium and calcium in the soil should not be allowed. Potatoes do not need potassium and calcium nitrate.
It is worth giving up adding such a "folk" remedy as banana peel. Do not overdo it with ash.
The ratio of nitrogen, potassium and phosphorus components should be approximately equal.
Watering of the crop should be frequent. Lack of moisture in the soil is a common cause of scab.
Earlier, summer residents were told whether it is possible to sprinkle ash under onions .
