Methods For Determining Lime Requirement exchange acidity of 10 meq/100g, what is the corresponding lime A measure of soil pH indicates whether or not lime is needed, but it alone is not sufficient for determining how much lime is needed. To estimate lime requirement of a soil, an estimate of the soil's buffering capacity is needed.

Lime Requirement Determination The lime requirement procedures described below, the SMP (Shoemaker-McLean-Pratt) and Adams-Evans buffer methods, were developed for distinctly different soils. The SMP method was designed for use with soils that have large lime requirements and significant reserves of exchangeable Al (Shoemaker et al., 1961).

Ground Quick Lime, a finely powdered form of calcium oxide, is indispensable in industries such as sugar refining, glass production, poultry farming, and metallurgy. Renowned for its versatile applications, it effectively regulates pH levels, serves as a fluxing agent, and facilitates disinfection processes.
