dc.description.abstractTillage exposes the soil to different mechanisms of mechanical decomposition, which crucially change its structure. Possible approach in controlling the quality of each specified operation and complete tillage process assumes establishing the functional relations between the operational parameters of applied mechanization and resulting mass probability density function of soil particle sizes. Based on experimental data from three independent experiments, the appropriate nonlinear relationships between the mass probability density functions of different soil fractions and particle diameters of these fractions. Calculations are based on the least squares fitting method. These expressions can facilitate modeling and prediction of soil fractions distribution and tillage quality control.en
dc.description.abstractMehanizovana obrada izlaže zemljište uticaju različitih mehanizama mehaničke dekompozicije, suštinski menjajući njegovu strukturu. Mogući pristup analizi kvaliteta svake pojedinačne operacije i procesa obrade u celini podrazumeva uspostavljanje funkcionalnih veza između radnih parametara primenjene mehanizacije i rezultujuće masene raspodele frakcija obrađenog zemljišta. Na osnovu eksperimentalnih podataka iz tri nezavisna eksperimenata, formulisane su odgovarajuće nelinearne veze funkcije masene gustine verovatnoće različitih frakcija obrađene oranice i pripadajućih prečnika čestica tih frakcija. Proračun je zasnovan na metodi najmanjih kvadrata. Dobijeni izrazi mogu olakšati modeliranje i procenu veličina frakcija zemljišta, kao i kontrolu kvaliteta mehanizovane obrade oranice.sr
