POTASSIUM RELATIONSHIPS IN SOME BRITISH COLUMBIA SOILS
Keyword(s):
The estimated amounts of micaceous minerals and of certain forms of K, namely total, slowly available, and exchangeable K, varied considerably among soils of southwest British Columbia. The amounts of different forms of K were related to the amounts of micaceous minerals. The amounts of the various forms of K in the soils were related to one another. The Vancouver Island soils formed on marine and glacial till parent materials contained less mica and K than the Lower Fraser Valley soils formed on Fraser river alluvium. In most instances the contents of the various forms of K were not related to the amounts of silt and clay in the soils.
