The Common

The experiments show that under these conditions the common trace nutrients, cobalt, copper, manganese, molybdenum and zinc are sufficiently completely extracted as chelates by shaking the soil extract with oxine-chloroform solution. The hydrogen ion concentration of the extract and the concentration of oxine in chloroform have decisive effects on the extractability. Using the reported and discussed procedure it is possible to separate the common trace metals from the major soil extract constituents, especially for spectrographic analysis.
