Mobility and distribution of cadmium, nickel and zinc

2006-10-13  In general, a low amount of Ni in the F4 fraction agrees well with the results reported earlier by Kashem and Singh .The concentration of Ni in the organically bound (F5) fraction was in the range of 9–15% of TNi in the A1-horizon but decreased with depth in all soils, which may be partly explained by the concomitant increase in residual Ni in the sub-surface horizons. The highest amount (57–85%) of Ni

Zinc in plants and soil - Got A Plant Problem?

Ideally, for healthy and productive soil the concentration of zinc should be 1‑200 mg/kg. If the concentration of nickel in your soil is greater than 7400 mg/kg it would be a good idea to test the food grown in your soil and seek expert advice about whether you need to take special corrective action in the levels are high.
