ECCE is the product of Effectiveness and__________.

The term ECCE stands for "Effective Calcium Carbonate Equivalent," which is a measurement used to express the neutralizing value of liming materials in relation to calcium carbonate. This concept helps in comparing the effectiveness of different liming materials based on how well they can neutralize soil acidity. The effectiveness component pertains to the amount of acid that the liming material can neutralize compared to pure calcium carbonate.

The second part of the term refers specifically to "Calcium Carbonate Equivalence." This is a standard used to indicate the effectiveness of various liming agents in terms of their ability to counteract soil acidity like that of a pure calcium carbonate source. The product of effectiveness and calcium carbonate equivalence provides a comprehensive understanding of how well a liming material will work in practice to raise soil pH.

Understanding ECCE is crucial for agronomists and crop advisors when recommending lime applications to improve soil health and crop production, as it informs how effectively a limited amount of lime can address the soil's requirements.
