Karakteristike akričnog luvisola na krečnjacima Magleša

Abstract

Na krečnjacima planine Magleš proučena su vrlo duboka zemljišta sa jasno izdiferenciranom dvoslojnom fiziografijom profila. Veoma izraženu morfološku diferencijaciju profila prate značajne teksturne razlike i variranje hemijskih osobina zemljišta. Profili su moćni 80-140 cm. Površinski deo soluma, žuto-smeđe boje, moćan je 30-90 cm. Teksturno pripada praškasto-glinovitoj ilovači. Hemijske osobine karakteriše jako kisela reakcija i veoma nizak stepen zasićenosti bazama. Reliktni (B) horizont je crvenkasto smeđe boje, karakteriše se vrlo visokim učešćem koloidne gline, jako je plastičan i kompaktne strukture. Reakcija je najčešće slabo kisela do neutralna, a stepen zasićenosti veoma visok. Rezultati obavljenih proučavanja potvrđuju pretpostavku da je eolski proces imao veliki uticaj na formiranje dubokih dvoslojnih profila na krečnjacima Magleša.

Very deep soils with clearly differentiated two-layered profile physiography were studied on the limestones of the mountain Magleš. The very marked morphological differentiation of the profile is followed by significant textural differences and the variation of chemical characteristics of the soils. The profiles are 80-140 cm deep. The topsoil part of the solum, yellow-brown in colour, is 30-90 cm deep. Its textural class is silty-clay loam. Its chemical characteristics are very acid reaction and very low degree of base saturation. The relic (B) horizon is reddish brown in colour, and it is characterized by a very high percentage of the colloidal clay, it is highly plastic and it has a compact structure. Its reaction is mostly weak acid to neutral, and the degree of base saturation is very high. The study results confirm the hypothesis of a very high impact of the Aeolian process on the formation of deep two-layered profiles on Magleš limestones.
