“…The presence of Staphylococcus sp was not a surprise as though this is not a bacterium found in the soil could be associated with the waste paper as a result of contact with human hands. Micrococcus sp and Pseudomonas sp have been reported as soil bacteria [18,19,22,23].The results obtained also showed that the presence of these pathogens in the soil could in turn affect the soil fertility by reducing plant nutrient uptake which in turn will affect plant growth. The increase in the microbial population with time agrees with the work of Lozana et al, [24] who reported that changes in microbial activity and community structure after compost application can lead to the increased of soil -borne plant pathogens.…”

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 x10 5 cfu/g for soil samples treated with composted waste paper and 5.0±0.78 to 6.1±1.29 x10 5 cfu/g for control. The results also revealed a total of eight bacterial genera and they include; Bacillus sp, Pseudomonas sp, E.coli, Micrcoccus sp, Staphylococuss sp, Proteus sp, Enterobacter sp, Klebsiella sp respectively. Total fungal count ranged from 1.5±0.97 to 2.9±0.92 x 10 5 cfu/g for soil samples treated with composted waste paper. A total of five fungal genera were isolated and they included Aspergillus sp, Penicillium sp, Mucor sp, Rhizopus sp, and Sacharomyces sp respectively. The most prevalent bacterium across the sample was Bacillus sp with 33.33 % while the most prevalent fungus across the sample was Penicillium sp with 41.67 %.

“…Germination studies of the maize seeds were carried out at day 4 to determine the number of seeds that have germinated using the, method of Jinadasa et al [17] and Ibuot et al [18]. Plant height was determined at 4 days interval.…”
