摘要:

Thirty‐two years after the addition of high rates of potassium to two Illinois experiment fields, the largest gain in soil K was in the acid‐insoluble form. Cation exchange capacity of the soil clays had decreased with the increasing addition of K, presumably due to fixation of potassium in the interlattice positions of clays. An X‐ray diffraction analysis did not provide any conclusive evidence as to the formation of illitic minerals.
