Secondary macronutrients are used in relatively large quantities by plants for optimal growth and are sulfur (S), calcium (Ca), and magnesium (Mg). Micronutrients on the other hand are needed in much smaller quantities than both primary and secondary macronutrients; however, micronutrients are still essential for plant growth. Often, soils in Virginia contain enough micronutrients and fertilizer amendments are not warranted. However, if needed, this publication will outline some possible secondary macronutrient and micronutrient fertilizer sources. Numerous formulations and blends are available from many different companies and dealers so be sure to read and follow your specific label carefully.
