Abstract

The metals such as Fe, Cu, Zn and Mn are the essential elements that have an important role in the human immune system. The aim of this research was to determine the concentration of nutritive values of macroelements (N, P, and K) and microelements (Fe and Zn) in a mushroom substrate and in a champignon mushroom fruiting body. A trial was conducted in the mushroom production company Romanjek LLC in Slavonski Brod, Croatia. It was conducted in four vegetation cycles on two different substrates, the one originating from Eastern Europe and the other originating from Northern Europe. At the end of the trial, the basic chemical properties of substrates and mushrooms were recorded. A comparison of investigated substrate measurements demonstrates that the highest content of elements N, P, and K was determined in the substrate 2 originating from Northern Europe, while the concentration of microelements Fe and Zn was higher in substrate 1, originating, from Eastern Europe. There was a statistically significant difference in a macroelement content in the mushrooms grown on the substrates of different origin, as well as in the transfer of Zn and Fe from a substrate to mushrooms. There was a higher accumulation of the transferred Zn in comparison to Fe in the mushrooms regardless of the origin of the substrate.
