Work by Col well and Brady (45) was conducted on Norfolk soils in North Carolina while data by Rogers (95) was obtained from work with Norfolk soils in Alabama. indicated that the critical level of exchangeable calcium for peanuts on Norfolk soils in Alabama was between and per 100 grams of soil. Colwell and Brady (45) also observed a correlation between the exchangeable calcium level of soils in North Carolina and the response of peanuts to additions of lime. The relationships between the lime re- sponse and exchangeable calcium level as reported by Rogers and by Colwell and Brady are shown in figure 6. It is interesting to note the dif- ferences in the data obtained by investigators in the two States. Little re- sponse resulted from liming soils in Alabama which contained more than.
