Part 1, Section 2: Soil Fertility Management
Soil Fertility Management
Test levels for calcium (Ca) and exchangeable acidity, and optional tests for organic matter, nitrate nitrogen, and soluble salts are provided in this section. Also included here are calculated values for the soil cation exchange capacity (CEC) and percent saturation of the CEC by K, Mg, and Ca. These calculated values are not used in making recommendations; they are provided for reference only. Zinc, Sulfur, and Copper results are also included in the report. These are not used to make recommendations but rather to flag potential deficiencies of zinc and sulfur that should be confirmed with plant analysis or potential toxicity of copper on dairy farms where copper sulfate is used extensively in foot baths.
