Abstract
In general, organic carbon, total nitrogen, available affective CEO and exchangeable cautions as wall a. clay and silt contents are low in soil of savanna zones of Nigeria. No obvious imbalance between Was, exchangeable cautions in the soils studied/observed. Mean ratio of Ca/Mg ilia. 85 while that of Mg/K was L.74. Exchangeable Mg seems to be that most vulnerable caution whose availability may create a problem for intensive and continuous cultivation.
