摘要

速測提供一個快速的土壤分析法以應用於肥料用量推薦，因此本研究利用英、美常用的兩速測方法，分別測試土壤中的氮、磷、鉀及pH，並比較分析兩種速測方法的異角及測試結果的相關性。針對22種土壤樣品速測分析的結果，兩種方法所得結果很相近。速測法所建立的施肥推薦量與文獻之施肥推薦量的比較方面，在氮鉀肥及石灰推薦量皆獻的推薦量有高度的相關且範圍相近，證明速測法所建立之施肥推薦量與文獻由實驗所得之施肥推薦量相符而有實用上的可行性。兩種速測方法各有其優點，因此在大部分分析結果都相近的前提下，建議使用其中測議程序較簡單且便宜的方法。

Quick test offered a rapid means for soil analysis well as fertilizer recommendations. We used the test kits popularly used in England and in USA to test the N、P、K and pH in soils. These two methods were compared and the results were correlated. We found the results of these two methods were compatible after 22 widely selected soil samples have been tested. Comparing the recommended application rate of fertilizers between the quick tests and the data from documents, we found that the recommendations of N、K fertilizer and calciferous fertilizer almost at the same level. The results proved that the recommendation based on quick test could be used in the field. Since the two methods have similar functions and results, we suggested the less expensive one be the choice for further application.
