The structure of vertisol soil in the area of the Municipality of Smederevo

Abstract

The objective of this study was to investigate the structure of vertisol, the aggregate distribution, and the stability of structural aggregates. The investigation was conducted in the municipality of Smederevo in eastern Serbia. At ten locations, disturbed samples, as well as soil samples for structure analysis were taken. The distribution of aggregates shows the high amount of macro aggregates, low content of aggregates 2-3 mm size, and according to the structural coefficient satisfactory structure. The stability of macroaggregates to dispersion by water in the arable layer of vertisol is excellent. The results of this research could be used in cultivation practices planning since there is a possibility of improving the structure of vertisol.

Cilj rada je bio da se ispita struktura smonice, distribucija agregata i stabilnost strukturnih agregata prema rasplinjavanju u vodi. Istraživanje je obavljeno u opštini Smederevo u istočnoj Srbiji. Na deset lokacija uzeti su uzorci u poremećenom stanju i uzorci zemljišta za analizu strukture. Distribucija agregata pokazuje veću zastupljenost makroagregata, nizak sadržaj agregata veličine 2-3 mm, a prema koeficijentu strukturnosti zadovoljavajuću strukturu. Stabilnost makroagregata u obradivom sloju smonice je odlična. Rezultati ovog istraživanja mogu da se koriste u planiranju poljoprivredne proizvodnje jer postoji mogućnost poboljšanja strukture smonice.
