Cassava root rot is a serious threat to cassava production worldwide. It reduces yields and adversely affects the growth of the crop. Depending on the causal agent, host susceptibility, and the environmental conditions, entire fields can be lost to this disease. A research was carried out in the Nkoranza South, Sunyani West and Dormaa East districts of the Brong Ahafo Region of Ghana to assess the physico-chemical properties of soils from fields infested with cassava root rot disease. Composite soil samples were taken from infested and non-infested cassava fields at two different depths (0 – 20 cm and 20 – 40 cm). Samples from the non-infested fields served as control. The samples were transported to the laboratory for analysis of pH, organic matter, nitrogen, phosphorus, potassium, calcium and effective cation exchange capacity. Generally, the results showed low to moderate levels of plant nutrients in the soil samples from both the infested and non-infested cassava fields in the three districts of Brong Ahafo Region. Plant nutrients may be said to have been depleted and to increase cassava yields the major plant nutrients i.e. nitrogen, phosphorus and potassium should be increased by applying chemical fertilizers.
