Soil is a major source of both macronutrients and micronutrients which are needed for plants to grow. The macronutrients are required in large quantities due to their importance in cellular components like proteins and nucleic acids. The micronutrients have essential and specific roles in molecules involved with energy transfer process and enzymes. On the other hand, in soils can be found toxic elements as well which have been added to soils due to the usage of fertilizers, pesticides and from atmospheric deposition. The purpose of the present paper is to determine the content of macronutrients (C, N, K, Mg, Ca), micronutrients (Fe, Na, Mn, Co, Mo, Zn, Cu and Ti) and heavy metals (Pb, Cd, Ni, Cr, As) from soil samples using ICP-MS (inductively coupled plasma- mass spectrometry) technique. In this study where used three types of soil: conventional soil, ecological soil and soil in the second year of conversion. Different quantities of nutrients were observed between the three soil samples during the conversion from conventional to ecological.
