  A 4x4 factorial experiment in a Randomized Complete Block Design (RCBD) with three replicates was used to study the effects of hydrated lime on the growth of maize crop at National Special Programme for Food Security (NSPFS) field FCT, Abuja. The results showed that all fertility related properties of the soil were low with moderate to slightly acidity and the exchange site saturated with H+. 0.25 ton ha-1 of hydrated lime+0.25 ton ha-1 of NPK 15-15-15+2 ton ha-1 of Farm Yard Manure (FYM) incorporated into top soil increased the growth of maize more significantly than either 0.5 ton ha-1 of hydrated lime or zero lime. Therefore, on the average 0.55 ton ha-1 of lime was recommended for the site.

  Pollution of the environment is of great concern, thus the present study investigated the concentration of trace metals in soil found around the major industrial areas of the Northwestern state of Nigeria, using atomic absorption spectrophotometry. The results obtained indicated that these metals on dry weight basis in the soil ranged between (0.1-0.7 μg g-1) Cd, (14.2-92.7 μg g-1) Cr, (151.5-540 μg g-1) Pb and (3.5-24.7 μg g-1) Ni. From the results, industrial areas seem to be relatively high in concentration of tested metals than those of the control sites. The soil pH of the sampling sites varied on the average from 6.5 to 7.12 in water indicating only a slightly acidic to neutral. The soil pH in CaCl2 is within the range of 5.49 to 6.39 indicating moderately acidic soil. Generally, the concentrations obtained were higher than the tolerable limit for safe environment as prescribed by Nigerian Federal Environmental Protection Agency (FEPA) and World Health Organization (WHO). The degree of pollution measured constitutes a threat to humanity and the ecosystem.
