This research work focused on bioconversion of waste paper into soil conditioner and its effect on plants growth and soil microbial population. The effects were studied for 21 days and the number of seeds germinated and their height were measured at 3 days interval. Percentage (%) seed germination across the samples was 100 %. The height of the plants in soil treated with composted waste paper ranged between 80±0.98 mm and 643± 1.76 mm that of control soil ranged between 70±1.98 mm and 503±1.67 mm. The result for the microbial analysis revealed a total bacterial count range from 4.0± 1.01 to 6.9±1.03 x105cfu/g for soil samples treated with composted waste paper and 5.0±0.78 to 6.1±1.29 x105cfu/g for control. The results also revealed a total of eight bacterial genera and they include;Bacillussp,Pseudomonassp,E.coli,Micrcoccussp,Staphylococusssp,Proteussp,Enterobactersp,Klebsiellasp respectively. Total fungal count ranged from 1.5±0.97 to 2.9±0.92 x 105cfu/g for soil samples treated with composted waste paper. A total of five fungal genera were isolated and they includedAspergillussp,Penicilliumsp,Mucorsp,Rhizopussp, andSacharomycessp respectively. The most prevalent bacterium across the sample wasBacillussp with 33.33 % while the most prevalent fungus across the sample wasPenicilliumsp with 41.67 %.  |
