Soils with low SMP values have high reserve acidity and high lime requirements. Conversely, soils that are acidic and have a high SMP buffer have a low lime requirement. Figure 4 shows the relationship between SMP test and lime recommendation.

WebTo make the buffer solution we combined two solutions of the base and acid with their original molarities and volumes known. The way Jay can skip the usual calculations and already know the final concentrations is by recognizing that the final is twice that the volume of the original solutions. And since molarity is the ratio of the number of ...

WebDue to its analytical practicality, the SMP buffer solution method has been widely used in Brazilian soil laboratories in estimation of soil potential acidity (H+Al) instead of the extracted by 0.5 mol L-1 calcium acetate solution.
