Distribution of aggregates in heavy soil after autumn tillage

Abstract

This paper presents the results of the soil type humogley, subtype non-carbonated, after autumn treatment for sowing wheat. Percentage of predominant contents of soil fraction from 1 to 9.5 mm in the amount of 51.67% without fractions larger than 50 mm (0%), indicates that treated soil sample is a good and realistic basis for testing the corresponding models. Among others, the results clearly show a significant dispersion of statistical parameters describing the distribution of soil fractions according to aggregate size, at different measuring points of sample plots.

U radu su prikazani rezultati ispitivanja zemljišta tipa ritska crnica, podtipa beskarbonatna, nakon jesenje obrade za setvu pšenice. Preovladava procentualna zastupljenost strukturnih agregata zemljišta od 1-9,5 mm u iznosu od 51.67 % i bez udela frakcija većih od 50 mm (0 %), što pokazuje da obrađeni uzorak zemljišta predstavlja dobru i realnu podlogu za proveru odgovarajućih modela. Pored ostalog, rezultati nedvosmisleno ukazuju na značajnu disperziju statističkih parametara koji opisuju zastupljenost frakcija zemljišta prema veličini strukturnih agregata, na različitim mernim mestima ogledne površine.
