WebzIn 1998 lime recs., SMP buffer pH does not contribute much to lime requirement (LR) {SMP contributes < 10% of LR zSMP is the single best predictor of LR but does not strongly influence LR {Soil pH and OM most influential {Questioned about significance of SMP zExample: Target pH = 6.8 OM = 3.5 soil pH = 6.2 buffer pH = 6.4 WebA soil pH of 7.0 is neutral and is used as a reference to categorize soils as acidic (pH less than 7.0) or basic (pH above 7.0). For the production of most crops a slightly acid soil, about pH 6.5, is most desirable. Table 1. pH …
WebAt pH 7, the concentration of H+ ions and OH- ions are equal, and the soil or solution is neutral. At pH values less than 7, the soil is acid; at values more than 7, the soil is alkaline. ...

WebSikora and SMP pH values ranged from 5.5–7.2 and 5.3–6.9, respectively, with a strong positive correlation (r = 0.9) (Figure 1). The strong correlation and linear nature of the relationship between Sikora and SMP suggests that Sikora could suitably replace SMP for lime recommendations in Kansas soils. However, since Sikora pH values were ...
WebThe SMP buffer has an initial pH of 7.5. Bases in the buffer react with soil acidity to reduce the pH of the buffer from 7.5 to some measured soil-buffer pH. The greater a decline in soil-buffer pH from an initial value of 7.5, the greater the …
