Keywords: | 比率律;活性比;Ratio law;Activity ratio | Issue Date: | Mar-1999 | Publisher: | 中華土壤肥料學會 | Journal Volume: | 2 | Journal Issue: | 1 | Start page/Pages: | 59-64 | Source: | 土壤與環境 | Abstract: | 本試驗乃以台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,此顯示所試驗的五種土壤皆符合比率律。 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. |
