中文摘要 | 本試驗乃以臺灣五種不同酸鹼度的農地土壤為材料,探討在不同水分含量情況下,其K-(Ca+Mg)活性比的變化情形,結果顯示,隨著土壤水分含量的增多,土壤溶液K離子及(Ca+Mg)離子濃度有下降趨勢,但其K-(Ca+Mg)的活性比變化並不大,此顯示所試驗約五種土壤皆符合比率律。 |
英文摘要 | Five farm soils of different pH were used to study the change in K-Ca activity ratio with the change in soil / water ratio. Results show that concentrations of K and Ca+Mg in soil solution decreased with the decrease in soil/water ratio, but the K-(Ca+Mg) activity remained practically constant, which is predicted by the ratio law. |
