The Soil and Plant Analysis Council is governed by a board comprised of academics, researchers and directors of laboratories involved in soil and plant science and nutrient management. Laboratory board members and individual industry class members represent research and laboratory industry experts with extensive experience in laboratory test methodologies, soil analysis, plant nutrition, and nutrient management. Board members are selected by the SPAC executive board and serve for a term of five years.

SPAC is overseen by an executive board consisting of president, president elect, past president each serving a two year term and a secretary/treasurer selected and approved by the board. Officers are selected from the board and serve a six year term rotating from elect, to president to past president. The SPAC executive board is responsible for oversight of council activities, ISSPA symposium planning and JB Jones Awards.

The SPAC board has a formal board meeting in the fall of each year, and additional telephone/internet conferences dependent on activities and specific projects.
