Plants are valuable and natural resources because they can provide us with the chemicals that humans need. Cannabis sativa L., also known as fibre hemp, is one of the oldest cultivated and herbaceous plants in the world, with many valuable natural components used by people since ancient times. Hemp plants are rich in nutrients and health-enhancing ingredients, including vitamins, mineral salts and macronutrients, and at least one hundred different cannabinoids. Deficiency of mineral nutrients such as Fe, I, Zn, Ca, K, Mg is a growing nutritional problem in human populations. The versatility of hemp leaves and stems and the composition of their components can lead to the sustainable development of many products for use in the food, cosmetic and medical industries. In order to promote environmentalfriendly and sustainable agricultural systems, fibre hemp has been reintroduced in both conventional and organic cropping systems in the last years, because it may reduce cereal monocropping, preserving soil fertility, and it is suitable for innovative industrial applications (i.e. biocomposites in automotive and constructions industries, raw materials for thermal insulation, oil and agro-fine chemicals, etc.). This study aimed to find out the amount of mineral composition of hemp morphological parts (Cannabis Sativa L.) during vegetation by means of inductively coupled plasma mass spectrometry (ICP-MS) method. In the present study, 3 hemp (variety Felina 32) raw materials (stems, leaves and blossoms) were analyzed. Samples were collected from Institute of Agriculture (LAMMC) field experiments. Investigated samples differ in their growing conditions. Different fertilization rate and density were applied. Mineral composition of digested hemp samples was investigated by means of ICP-MS method. Obtained results, as well as sample preparation methodology step by step, will be presented at the conference.
