Soil Chemical Analysis

Most questions of soil nutrients can be resolved by a Standard Soil Package, S001, which reports pH (1:1 H2O), Organic Matter %, soluble sulfur, estimated nitrogen release (lb/A), Bray II and Mehlich III phosphorus, and exchangeable cations and % base saturation of Calcium (Ca), Magnesium (Mg), Potassium (K), and Sodium (Na), by Mehlich III extraction, and extractable minor elements iron (Fe), manganese (Mn), copper (Fe), aluminum (Al), zinc (Zn), and boron (B).

The saturated soil paste method is available, with or without client water. Other extractants are available including Bray I instead of Bray II, also, the SMP/Sikor Buffer pH. Individual tests are available for specific elements.
