A note about calcareous soils with high pH
The calcareous soils of Miami-Dade and other counties typically have soils up to 80% CaCO3. A comparable calcareous soil in other regions of the US will have around 10-20% CaCO3. It is therefore unique. Years of research has shown limited calibration among various soil extractants and nutrients. Currently, the soil extractant identified and recommended on such soils is AB-DTPA, which has shown calibration with only phosphorus, with a critical limit of 10 mg/kg. However, due to long term intensive management of agriculturally managed calcareous soils in FL, the soil P levels are around 30 mg/kg, generally rendering the approved AB-DTPA method to be of a limited value. Other nutrients such as K, etc did not yield in any reasonable calibration.
Efforts are still on-going to identify a suitable soil extractant for these soils and latest information can be obtained by contacting Dr. Yuncong Li, Soils Professor at the IFAS Tropical REC, Homestead. We therefore recommend that soil tests should be done under the advisement of the local County Extension office or the TREC.
