o:781 CHEMICAL AND GRANULOMETRIC PARAMETERS OF AGRICULTURAL SOIL IN THE SURČIN AREA - REPUBLIC OF SERBIA en Abstract: In the period from June to October 2019, tests of chemical properties and granulometric composition of 280 composite soil samples were conducted in the area of Petrovčić and Progar, Surčin Municipality (Belgrade, Serbia), to a depth of 30 cm. The presence of total sand, clay and silt fractions in the analyzed soil samples indicates a relatively uniform granulometric composition (textural class of light clays), but with unfavorable ratio of total sand/clay fractions, in which the clay fraction prevails. The largest number of soil samples has strongly acidic, medium and acidic values of substitution and active acidity, are carbonate-free, while the values of electrical conductivity are very low and indicate the complete absence of salinity in the surface soil horizon/layer. The largest number of soil samples is moderately provided with total nitrogen and humus, with very low, low and medium content of easily available phosphorus, as well as medium (CM Petrovčić) to high and medium provided with easily available potassium (CM Progar). The obtained results indicate that the studied soils of Petrovčić and Progar are suitable for intensive field production. However, low pH values indicate an adequate application of limestone and fertilizers, as well as measures such as undermining and drainage. 2022-10-13T11:59:41.054Z 44 no 46 Aleksandra Stanojković-Sebić Institut za zemljište 0000-0002-5176-9827 46 Zoran Dinić Institut za zemljište 0000-0003-4109-4106 46 Jelena Maksimović Institut za zemljište 0000-0001-5217-3972 46 Darko Jaramaz Institut za zemljište 0000-0003-1715-1748 46 Marina Jovković Institut za zemljište 0000-0001-7224-8556 46 Radmila Pivić Institut za zemljište 0000-0002-5848-1551 application/pdf 862098 https://unilib.phaidrabg.rs/o:781 no yes 1 70 1556237 71A05 Proceedings of 27th International Symposium on Analytical and Environmental Problems, Szeged, Hungary 308 312 2021
