Main chemical properties of Srem soils

Abstract

The objective of this study was to check the fertility of soils in the region of Srem through the analysis of the main chemical soil properties. Locations for soil sampling have been determined by means of a 4x4 km grid superimposed over a soil map of the Vojvodina Province R 1:50,000. GPS coordinates were given for each sample site. The results of this study provide a solid basis for soil quality and environment status estimations. Compared against the previous round of studies (Hadžić et al., 1993), there occurred a moderate soil alkalization, except in forests typically established on the brown forest soil and pseudogley. Humus reduction was registered in most soil types except the alluvial and alluvial-diluvial soils and in forested areas. Total nitrogen varied in unison with humus content. Considering the mean values of available phosphorus and potassium for the entire region of Srem, decreasing trends were seen as compared with the previous round of studies.

U cilju kontrole plodnosti i sagledavanja sadržaja opasnih i štetnih materija u zemljištima Srema i eventualno njihove degradacije u širem smislu, u toku septembra i oktobra 2006. prikupljeno je 250 uzoraka zemljišta. Svaki uzorak prate i podaci o njegovom tačnom položaju sa koordinatama i nadmorskom visinom. U radu je prikazan deo istraživanja koja se odnose na osnovna hemijska svojstva zemljišta. Najveći broj uzoraka zemljišta ima umereno alkalnu reakciju (prosečna vrednost za sve ispitivane uzorke pH u H2O 7,83) i dobro su obezbeđeni humusom (oko 70% uzoraka ima sadržaj humusa u granicama od 2 do 4% sa prosečnim sadržajem od 3,01 %). Srednji sadržaj CaCO3 iznosi 5,79%. Sadržaj lako pristupačnog fosfora i kalijuma nalazi se na optimalnom nivou (srednja vrednost P2O5 22,70 mg/100g a K2O 21,88 mg/100g zemljišta).
