Calcium Soil Test Procedures

Calcium levels in soil are tested as part of a routine soil analysis. Along with a soil's pH, nitrogen, potassium, phosphorous and other micro-nutrient levels, calcium is part of the complete profile of a basic soil test.

Collecting Samples
- Ensure your soil collection tools are sterile.
  
  Requirements for collecting samples vary depending on the lab used, but in general they all require a representative sample of the testing area. Collect a composite of the soil by taking four to six samples with a sterile tool such as a trowel, and mix together in a clean container. In the packaging supplied by the lab, place approximately 2 cups of the mixed soil to send for analysis.
The Analysis
- The soil analysis reflects existing calcium levels as well as recommended rates to apply.
  
  Existing calcium levels may be expressed as parts per million (ppm), and recommended amendments may be expressed as pounds per acre (lb/a). To achieve ideal calcium levels, you may need to apply 800 to 1600 lbs. of calcium per acre if your soil is deficient.
Role of Calcium in Soil
- The balance of calcium (Ca), magnesium (Mg) and potassium (K) in the soil needs to be maintained.
  
  Calcium has a vital function in plant life. It allows for the retention and transport of other vital nutrients within the plant. Also, calcium requires a careful balance with magnesium and potassium; an imbalance of any part of the three affects the other two negatively.
