These soils were acidified over thousands of years by inputs of acids from atmospheric sources (carbonic, sulfuric, and nitric acid), the decay of plant and animal residues, and removal of basic cations by the natural processes of leaching. If our native soils are not limed (basic), the pH is often in the 4.5 to 5.5 range.

Assessment of copper, cobalt and zinc contaminations

The infiltration of heavy metals into soils through steel plant production processes is one of the most important soil pollution sources. The aim of this study was to determine copper (Cu), cobalt (Co), and zinc (Zn) concentrations in soil and plant shoots around the Esfahan steel company (ESC). In this study, we separated 17 zones based on soil maps and marked 54 points for soil sampling.

Effects of calcium on nickel tolerance and

Nickel (Ni) phytoextraction using hyperaccumulator plant species to accumulate Ni from mineralized and contaminated soils rich in Ni is undergoing commercial development. Serpentinite derived soils have a very low ratio of Ca/Mg among soils due the nature of the parent rock. In crop plants, soil Ca reduces Ni uptake and phytotoxicity, so it is possible that the low Ca of serpentine soils could ...
