Content and Mobility of Iron in Acid Soils Of Central Serbia

Abstract

The paper gives an overview of many years investigation of Fe status in acid soils of Central Serbia in the term of its content, mobility and availability to cultivated plants. Numerous investigation showed low mobility and low availability Fe in acid soils. The concentration of this microelement in commutable fraction was 0.01%. Also, distribution and mobility of Fe in soils’ horizons in different oxido-redox conditions was very heterogenous. The highest presence of Fe in acid soils was in form of residual fraction (over 80%).

U radu je dat pregled višegodišnjeg proučavanja sadržaja, mobilnosti i pristupačnosti gvožđa u kiselim zemlјištima Centralne Srbije. Brojna istraživanja su pokazala nisku mobilnost i malu pristupačnost Fe u ovim zemljištima. Koncentracija ovog mikroelementa u razmenlјivoj frakciji je iznosila 0.01%. Takođe, distribucija i mobilnost Fe u zemljišnim horizontima u različitim oksido-redukcijonim uslovima je bila veoma heterogena. Najveće prisustvo Fe u kiselim zemljištima je bilo u rezidualnoj frakciji (preko 80%).
