The identification of visual symptoms of deficiencies is a widely used method in the diagnosis of nutritional problems in agricultural and forestry production. The aim of this study was to characterize visual symptoms of deficiencies of N, P, K, Ca, Mg, S and B, in seedlings of the andean oak, Quercus humboldtii Bonpl., under nursery conditions. Seedlings were planted in polythene bags, where fertility treatments were applied according to the method of Jenny. After 4 months of development, we photographed seedlings and leaves with symptoms of nutritional deficiencies and determined leaf nutrient content. Deficiency symptoms were detected for all nutrients studied, except B. Seedlings deficient in each nutrient had lower concen...
