Availability of Nickel in Soil Evaluated by Various Chemical Extractants and Plant Accumulation

Soil and Plant Nitrogen Availability

Accumulation and Soil-to-Plant Transfer Factor of Lead and Manganese in some Plant Species in Semnan Province, Central Iran

Background: Heavy metals have detrimental effects on the health of human being. The values of manganese (Mn) and lead (Pb) in some plant species and soil samples in an arid area of Iran were evaluated in this study. Methods: The values of Pb and Mn in 94 plant samples from 8 plant species and the related soil samples in 2010 were considered in Shahroud and Damghan, central Iran. Moreover, th...

Chemical fractionation and heavy metal accumulation in the plant of Sesamum indicum (L.) var. T55 grown on soil amended with tannery sludge: Selection of single extractants.

A pot experiment was carried out to study the single and sequential extractions of metals in different tannery sludge amendment and the potential of the plant of Sesamum indicum L. var. T55 (sesame) for the removal of metals from tannery waste contaminated site. The metal extraction efficiency obtained with each extractants was slightly different and follow the order; EDTA>DTPA>NH(4)NO(3)>NaNO(...

Stanford and Smith (1972) developed a biologically based, long-term incuThe success of variable rate N fertilizer application rests on our bation method whereby potentially mineralizable N can ability to predict the contribution of soil N to growing crops. We assessed relationships between soil N availability indices (SNAIs), be estimated using one-pool (Stanford...
