Forms of Iron and Their Association with Soil Properties in Four Soil Taxonomic Orders of Arid and Semi‐arid Soils of Punjab, India

Abstract

Profiles of arid and semi-arid zones soils of Punjab, northwestern India, were investigated for different forms of iron (Fe)

Spatial variability of heavy metals in the coastal soils under long-term reclamation

“…However, a negative relationship between Fe t and Fe d , and a non-significant relationship between Ni t and Ni d , were observed, which were supported by similar observation presented by Katyal and Sharma (1991) and Caridad-Cancela et al (2005). This observation may possibly be explained by soil physical attributes and hydraulic properties obscuring the availability and accumulation of these metals (Cook and Coles, 1997;Sharma et al, 2008).…”

Chemical Fractions of Iron and Manganese with Different Physico-Chemical Properties in Polyhouse Soils of Himachal Pradesh, India

“…The variation in the amount of total iron may be attributed to the fact that these soils have developed over varying parent material. The results are in line with those reported by Sharma and Chaudhary (2007), Sharma et al, (2008). Abundance of various Mn fractions was found to be in order of: W.S.…”

Distribution and forms of iron in the vertisols of Serbia

“…The origin of heavy metals in the soil is mainly geochemical (originating from the parent substrate) and partly anthropogenic (various sources of pollution). 8 Complexation of iron by soil organic matter may result in increased plant availability, and microbial exudates can supply additional iron to plant routes. [2][3][4][5] The bioavailability, mobility and chemical reactivity of heavy metals in soils are often associated with their distribution among certain soil fractions and the dynamic equilibrium among them.…”
