Abstract

Cilj ovog diplomskog rada bio je određivanje utjecaja mineraloškog sastava na parametre i procjednu vodu u profilima pseudoglejnog tla na vinogradarskom području pokušališta Jazbina. Analizirali su se prikupljeni uzorci profila s vrha, sredine, i dna padine, te se u tri navrata s razmakom od mjesec dana uzorkovala procjedna voda iz lizimetara za potrebe kemijskih analiza. Na uzorcima tla izvedena su laboratorijska istraživanja rendgenske difrakcijske analize (XRD) originalne i glinovite frakcije uz dodatne tretmane, određivanje kapaciteta kationske zamjene (CEC) metodom Cu-trien, volumnog udjela čestica laserskom difrakcijom, snimanje obiju frakcija metodom prijenosne rendgenske fluorescencije (pXRF), ukupna koncentracija elemenata u tlu određenih induktivno spregnutom plazmom (ICP-OES) i atomskom apsorpcijskom spektroskopijom (AAS), određivanje granulometrijskog sastava tla dobivenog metodom prosijavanja i sedimentacije, pH reakcije tla, električne vodljivosti (EC) te sadržaj udjela organskog humusa u tlu. Na uzorcima vode prikupljenim iz lizimetara analizirana je kemijska kakvoća procjedne vode (pH, EC, NH4+, NO3-,PO43-, Cl-, SO42-, K+, DOC, Cu, HCO3-, Na+, NO2-). Prema rezultatima analiza utvrdila se povezanost mineralnog sastava s CEC-om. Osim toga utvrđena je i povezanost mineralnog sastava s pojedinim elementima u tlu i procjednoj vodi. U uzorcima s višim CEC-om odnosno s većim udjelom minerala glina i Fe-oksida (goethita) koji su se nalazili u dubljim dijelovima izmjerene su više koncentracije kationa. Većina analiziranih elemenata i spojeva se akumulirala na dnu padine.

Abstract (english)

The goal of this master's thesis was to determine the influence of the mineralogical composition on soil parameters and percolating water in profiles of pseudogley soil in Jazbina viticulture and winemaking experimental site. Samples from the top, middle, and bottom of the slope were analysed, and percolating water was sampled for chemical analysis from lysimeters three times with a one-month interval. Laboratory analysis of soil samples included X-ray diffraction analysis (XRD) of the original and clay fractions with additional treatments, determination of cation exchange capacity (CEC) using the Cu-trien method, determination of particle volume content by laser diffraction, imaging of both fractions using portable X-ray fluorescence (pXRF), determination of the total element concentrations in soil determined by inductively coupled plasma optical emission spectroscopy (ICP-OES) and atomic absorption spectroscopy (AAS), determination of soil particle size distribution obtained by sieving and sedimentation, determination of soil pH, electrical conductivity (EC) and organic humus content in the soil. Laboratory analyses of the chemical quality of percolating water samples collected from lysimeters included pH, EC, NH4+, NO3-, PO43-, Cl-, SO42-, K+, DOC, Cu, HCO3-, Na+ and NO2-. Based on the analysis results, a connection was established between mineralogical composition and CEC. Additionally, a correlation was identified between the mineral composition and specific elements in the soil and percolating water. Higher concentrations of cations were measured in samples with higher CEC and with a higher content of clay minerals and iron oxides (goethite) found in deeper layers. Most of the analysed elements and compounds accumulated at the bottom of the slope.
