WebA buffer (TSM) was developed to reproduce the behavior of the SMP buffer in the estimate of potential acidity of Brazilian acid soils. This buffer contains four weak bases (TEA, MES, calcium acetate and imidazole) and calcium chloride to control the ionic strength. The efficiency of the new buffer in imitate the SMP was evaluated in twenty one Brazilian … WebThe method was calibrated against lime requirements to increase pH values to 5.5, 6.0 and 6.5 based on CaCO3 neutralization curves of the soils. A modification of the ratio of SMP-buffer to soil, which gives lower lime requirements per unit of pH depression is suggested for the use of soils that have rather low buffer capacities. how much is the powerball worth
