Often, summer residents notice that from year to year the potato harvest becomes worse and worse.
To correct the situation, fertilizers are not needed. Experienced gardeners manage without "chemicals".
Long-term cultivation of the same variety inevitably leads to a decrease in yield. Therefore, experts advise updating the planting material every 5-6 years.
Experts recommend replacing old seed potatoes with specially improved, high-quality material that experienced farmers grow specifically for planting.
According to experts, this is the only option that really helps reduce the risk of diseases and rot. Fertilizers do not work, and folk remedies do not help in particular.
Surface treatment will not protect against viruses, bacteria and fungi inside the tuber itself. Therefore, only replacement of planting material will help to avoid a systematic decrease in yield.
