抄録

The author has tried to find out an optimum base composition in upland soils of Kanagawa prefecture. The experiment was conducted in a mulitifactorial design with 27 combinations replicated three times. As the test plants, seven crops were grown including herb vegetables, fruit vegetables and root vegetables. Based on the results, an optimum exchangeable base composition in volcanic ash soil is infered as follows : 1) Optimum ratio for Ca : Mg : K is 60 : 25 : 15. 2) Optimum Ca-, Mg-, and K-saturation of CEC is 48%, 20%, and 12% of CEC, respectively, and optimum total base saturation degree is 80%. When expressed in pairs of base, CaO/MgO = 2.4, CaO/K_2O = 4.0, and MgO/K_2O = 1.7.
