Plant and Soil Aims and scope Submit manuscript

Summary

Field observations were carried out on an Egbeda soil series in western Nigeria to study the degree of soil-nutrient variability within and between plots due to pre-clearing vegetation. The soil showed lower soil pH, organic C, exchangeable K and Ca contents following cassava grown by traditional methods than following secondary forest vegetation or thicket regrowth. Except for exchangeable K, the degree of variability of the above parameters was observed to be in the following order: secondary forest vegetation > thicket regrowth > cassava plots. The available P status was generally low and showed little relation to pre-clearing vegetation. The implications of soil variability due to pre-clearing vegetation on soil sampling and in field experimentation are discussed. re]19760204
