Nutrient content evaluation was carried out to examine the condition of nutrient supply and a potential risk of contamination that could arise from an inappropriate application of mineral fertilizers (from a non-imission input). Results from measuring the amounts of three macroelements and three microelements in the soil used for the experiment carried out in a roof garden show the following tendencies: good up to a high amount of K, Mg, high up to very high amounts of Ca and Mn and slight contamination of soil by Cu and Zn approved analytically. The measured pH values suggest acid soil reaction, which in 2 years showed an increasing tendency. It is supposed to be a result of natural acidification of the soil due to precipitation activity.
