Specificity of mineral nutrition in virus-free potatoes is discussed in the paper. It is shown that healthy potatoes differ considerably from the infected ones in total output of nutrients, N:P:K-ratio, effectiveness of using the consumed nutrients for yield formation, and in the intensity of nutrients' output in critical periods of consumption. It is concluded that virus-free potatoes respond more to application of fertilizers and are more sensitive to nutritional background of the soil than the infected ones. For this reason the introduction of virus-free potatoes into farm production requires correction in the system of applying fertilizers
