Popis:	The effectiveness of three local liming materials: basic slag (a byproduct of iron and steel industry), cement flue dust (a waste product of cement factory), and ground limestone was compared with that of imported hydrated lime in a greenhouse study using acid soils from two sites in Southern Nigeria. The soils were taken from Onne, near Port Harcourt in Rivers State and Epe near Lagos in Lagos State. The soils were classified as Typic paleudult and Typic udipsamment, respectively. The results show that the four liming materials were capable of neutralizing soil acidity. Their relative effectiveness was in the order: hydrated lime > basic slag > cement flue dust > ground limestone. Uptake of phosphorus (P), potassium (K), and calcium (Ca), and dry matter yield increased with increasing lime rates up to 500 and 1,000 mg Ca/kg soil for Epe and Onne soils, respectively. The lime requirements of the two soils are in the order of the aluminum (Al) saturation of the effective cation exchange capacity (...
