In this bachelor thesis chemical characteristics were investigated of three soil samples: soil without added digestate, soil to which digestate was added 17 months ago, and soil with digestate added a few days before sampling, to see the impact of digestate on the tested soil. The characteristics of the samples that were determined are acidity, humus, ammonium nitrogen, carbonates, physiologically active lime, exchangeable aluminum and heavy metals (copper, zinc, cadmium, chromium, nickel, lead). According to the obtained results, all samples of soils belong to the group of moderately acidic, or weakly acidic to neutral soils. All samples are very weakly humus soils with a low supply of nitrogen, carbonates and physiologically active lime. The aluminum content in the soil without digestate is 0.05 mg and 0.15 mg in samples with digestate. The concentrations of heavy metals in the tested samples and digestate were determined using the technique of inductively coupled plasma mass spectrometry (ICP-MS), and the obtained results were compared with each other. In the digestate sample, the lowest determined concentration of tested heavy metals was measured for cadmium (0.43 mg kg -1 ), and the highest for zinc (318.00 mg kg -1 ). In the soil samples, the lowest determined concentrations of the tested heavy metals were measured for cadmium, whose concentration reached the highest value in the soil sample to which the digestate was added 17 months ago (0.07 mg kg -1 ). The highest concentrations of tested heavy metals were measured for lead, whose concentration reached the highest value in the soil sample to which digestate was added 17 months ago (12.38 mg kg -1 ). By comparing the obtained results for digestate and soil samples with Pravilnikom o nusproizvodima i ukidanju statusa otpada, apropos Pravilnikom o zaštiti poljoprivrednog zemljišta od onečišćenja, certain concentrations of heavy metals do not exceed the limit of maximum permissible amounts (MDK).
