Sažetak
Soil organic matter content is one of the main issues of European soils and agriculture in general. It is the basis for balancing nutrients and issuing fertilizer recommendations for achieving high and stable yields. The aim of the research is to determine the content of organic matter in the arable horizons in different soils at Eastern Croatia. The study was conducted on 165 locations and 9 dominant soil types in Eastern Croatia including their arable horizons. The soil organic matter was determined based on the organic carbon content(C) followed by sulfochromic oxidation prescribed in ISO 14235. According to the determined analytical values of organic matter content, studied soil samples were classified into five categories: very low organic matter content of the soil (<1% organic matter) 1 soil sample, low organic matter soils (1-3% organic matter) 119 soil samples, plenty of organic matter content of the soil (3-5% organic matter) 37 soil samples, intensely organic matter soils (5-10% organic matter) 7 soil samples and extremely intense organic matter soils (>10% organic matter) 1 soil sample. The average value of organic matter, considering all the investigated samples, was 2, 65% with a range from minimum 0, 83% to maximum 11, 80%. The maximum average value of organic matter content in the soil was determined in the humic gleysols (4, 94 %) and it was statistically higher in comparison to other investigated soils. Decrease of organic matter was determined according to the soil type: humic gleysols (4, 94%) < stagnic gleysols (3, 25%) < gleysols (2, 68%) < eutric cambisol (2, 51%) < fluvisol (2, 43%) < endogleyic stagnosol (2, 37%) < stagnosol (2, 26%) < luvic stagnosol (1, 93%) < luvisol (1, 87%).
