The Use of Limestone in Agriculture

In many countries, agriculture accounts for 1 to 2 % of the limestone market. While this may appear to be a relatively small proportion, the tonnages involved can be large (e.g., in the U.S.A. they exceed 13 million tpa [10.1]. 

Most of the limestone used in agriculture is applied directly to the soil. Smaller amounts are used as a filler and conditioner in fertiliser formulations. It is also used in animal feeds, and as poultry grit. Furthermore, limestone is increasingly being employed to combat the adverse effects of acid rainfall.
