The research work exploited the extent of cyanide pollution and major nutrients (elements) distribution in soils within three cassava processing industries in Akure metropolis, Ondo state Nigeria. The result of the research revealed that the top soil of cassava processing industries are richer in soluble cyanides than subsoil: the highest amount (118.85 mg/l) of soluble cyanide was obtained in the top soil of Igbatoro cassava processing industry while the subsoil of Aba-oyo cassava processing industry had the least soluble cyanide content of 82.906 mg/l. Trace of cyanide was also noticed in the well water of Igbatoro cassava processing industry that was sampled. The pH of the soils sampled followed a pattern that revealed that cyanide content determines the pH value of the soil to a large extent. The major nutrients distribution in the top and subsoils of the cassava processing industries revealed that nitrogen (N), phosphorus (P) and potassium (K) content of the cassava processing topsoils and subsoils were very high; nevertheless, the subsoils in the three industries are richer in N, P and K than the topsoils. Effluents from cassava industries increase soil nutrients and reduce pH.
