全台農田平地表土層土壤網格肥力資訊

本資料係以地面250公尺×250公尺之土壤網格方式儲存全台平地農田表土層肥力採樣分析成果，包括:土壤 pH值;土壤有機質;陽離子交換率;孟立克三號抽出液檢測(M3)之磷、鉀、鈣、 鎂、硼、銅、鐵、錳、鋅;1M醋酸銨抽出液檢測(NH4)之鈣、鎂、鈉、鉀、錳及鈣鎂比等項目。

This dataset stores the soil fertility sampling and analysis results of topsoil layers in flat farmlands across Taiwan, arranged in a 250 m × 250 m soil grid. The tested indicators include: soil pH; soil organic matter; cation exchange capacity (CEC); phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), boron (B), copper (Cu), iron (Fe), manganese (Mn), and zinc (Zn) as determined by Mehlich-3 extraction (M3); and calcium (Ca), magnesium (Mg), sodium (Na), potassium (K), manganese (Mn), and the calcium-to-magnesium ratio as determined by 1M ammonium acetate extraction (NH4-based detection).
