Fluid lime is a term that is generally used to describe the concept of suspending liming materials of various types in either water or fertilizer solutions. Frequently, the liming material in fluid lime is finely ground agricultural limestone with a high neutralizing value. Advantages include rapid availability and application with existing fluid fertilizer equipment.
Drawbacks are low rates of application and relatively high cost for the lime applied.
The displaced hydrogen then reacts with carbonate, reducing soil acidity. Carbonate dissolved from the limestone materials forms carbonic acid. Carbonic acid is not stable in soils and quickly forms carbon dioxide and water. The chemical reaction for this process is shown below. Everything that contains calcium or magnesium is not necessarily a liming material.
