Abstract
Vegetable mineral content represents an important source of minerals that are involved in basic metabolic processes in human body. Nevertheless, growing vegetable on alkaline, calcareous soils may result with P, Zn, Mn and Fe plant deficiency since these elements are firmly bound in precipitates of low solubility and consequently their availability to plants is markedly decreased.
Therefore, the aim of our experiment was to determine influence of different fertilization treatments on mineral and nutritional value of radicchio as valuable food.
The results showed that soil application of organic fertilizer (with humic and fulvic acid + macro and microelements) significantly increased P, K and Mg radicchio leaf concentration. Furthermore, in comparison to the other treatments, relative increase of iron content within organic fertilizer soil application is noticeable.
