Side-by-side graphs comparing the effect of rates of lime (graph a) versus rates of basalt (graph b) on raising the pH of a Goldsboro soil.

Figure 3. Effect of lime rates (a) and basalt rates (b) on the soil pH of a Goldsboro soil after 90 days of incubation. Lime rates were calculated considering an agricultural lime with ENV (effective neutralizing value) of 61%.
