Description

Four methods of K-fixation were examined by two kinds of soils as follows :
(1) Drying soils for 12 hours at 100℃.
(2) Drying soils on water bath.
(3) Alternately watting and drying the soils on water bath five times.
(4) Warming the soils for 30 days at 30℃.
The results of this exprriment were as follows :
