Abstract

Cilj rada bio je odrediti utjecaj načina korištenja zemljišta na odabrana svojstva Humofluvisola. Istraživanje je provedeno 2023. godine na pokušalištu Agronomskog fakulteta u Zagrebu na 4 lokacije, pod različitim načinom korištenja zemljišta: oranica, livada, vrt i voćnjak. Na svakoj lokaciji uzeta su 3 prosječna uzorka površinskog horizonta tla (0-30 cm). U uzorcima su određeni mehanički sastav (tekstura), pH, količina i karakter humusa, karbonati te K2O i P2O5. U svim uzorcima utvrđena je... More praškasto ilovasta tekstura. Signifikantno niže pH vrijednosti utvrđene su u voćnjaku, u odnosu na ostale načine korištenja tla. Značajno viši sadržaj humusa u tlu utvrđen je na livadi (4,40 %) u odnosu na tla korištena u poljoprivrednoj proizvodnji (2,47-3,11 %). Tlo voćnjaka je nekarbonatno, a kod ostalih načina korištenja slabo karbonatno (0,64-1,95 %). Tla u oraničnoj i povrćarskoj proizvodnji imala su prosječno više koncentracije fiziološki aktivnog fosfora (18,75 i 22,08 mg/100 g tla) u odnosu na tlo pod livadom (9,36 mg/100 g tla). Tla pod voćnjakom, imala su signifikantno niže koncentracije P2O5 (10,48 mg/100 g tla) u odnosu na tla pod oranicom i vrtom. Prosječna koncentracija K2O u tlu voćnjaka (22,5 mg/100 g tla) bila je signifikantno viša u odnosu na tlo pod prirodnom vegetacijom (14,6 mg/100 g tla). Less

Abstract (english)

The aim of this study was to determine the impact of land use on selected properties of Humofluvisol. The study was conducted in year 2023 on experiment station of the Faculty of Agriculture in Zagreb on 4 locations, under different land uses of: arable land, meadow, vegetable garden and orchard. Three average top-soil samples (0-30 cm) were taken from each location. The particle size distribution (texture), pH, content and character of humus, carbonates, K2O and P2O5, were determined in... More the soil samples. A silty loam texture was determined in all soil samples. A significantly lower pH values were determined in the soil of orchard in comparison to the other study locations. A significantly higher humus content was determined in the meadow (4.40 %) compared to the soil used in agricultural production (2,47-3,11%). The orchard soil was non-calcareous, and the other soils were slightly calcareous (0,64-1,95%). Soil in arable land and vegetable production had an average higher concentration of physiologically active phosphorus (18,75 and 22,08 mg/100 g of soil, respectively) in comparison to the soil from the meadow (9,36 mg/100 g of soil). Soil from the meadow had a significantly lower concentration of P2O5 (10,48 mg/100 g of soil) in comparison to the soil from the arable land and the vegetable garden. The average concentration of K2O in the orchard soil (22,5 mg/100 g of soil) was significantly higher in comparison to the soil under natural vegetation (14,6 mg/100 g of soil). Less
