Which liming material has the highest CCE of 179?

The liming material known for having the highest Calcium Carbonate Equivalent (CCE) of 179 is burned lime, also referred to as quicklime or calcium oxide. CCE is a measure of the neutralizing value of lime, indicating how effectively a liming material can raise soil pH and improve soil conditions. Burned lime has a high CCE due to its chemical composition, which allows it to react more readily with soil acidity compared to other liming materials.

Burned lime's effectiveness comes from its highly reactive nature. When it is added to soil, it quickly hydrolyzes to form calcium hydroxide, which in turn raises the soil pH efficiently. This makes it a powerful option for soil acid management in agricultural practices.

Other liming materials like dolomitic limestone, hydrated lime, and calcitic limestone, while still effective, typically have lower CCE values. Dolomitic limestone provides magnesium in addition to calcium and has a lower CCE than burned lime. Hydrated lime has a CCE that is lower than burned lime but still relatively high, while calcitic limestone primarily supplies calcium and has a CCE that is not as high as that of burned lime. Each of these alternatives has its place in nutrient management, but
