Title

DIVERSITY AND ABUNDANCE OF MICROBES, PH AND ORGANIC MATTER IN SOILS OF DIFFERENT FOREST TYPES IN TROPICAL HUMID LOWLAND FOREST ECOSYSTEM, NIGERIA

Pages

  333-341

Abstract

 This study examined the diversity and abundance of microbes, pH and organic matter of soils cultivated with three different plantation species and an adjacent natural forest in tropical humid lowland forest ecosystem, Nigeria. The plantations were unthinned stands of Nauclea didderrichi, Gmelina arborea and Tectona grandis established in 1979 in Akure FOREST RESERVE, Ondo State, Nigeria. Soil samples were collected (at a depth of 0 -15 cm) from four randomly located plots of 20 x 20 m in each forest type with soil auger. In general, there were 33 and 23 species of bacteria and fungi respectively in the soil samples.The population of bacteria ranged between 26.14 x 106 and 36 x 106 MPN g-1 dried soil while that of fungi ranged between 2.50 x 106 and 23.34 x 106 MPN g-1 dried soil. Highest species diversity and population of the microbes were isolated in soil samples from the natural forest and the least from Tectona grandis stand. Microbial diversity and abundance were influenced by soil pH and organic matter. There was no significant difference in organic matter and pH of soils from the four forest ecosystems (p<0.05) but significant difference was discovered to exist in the bacteria and fungi population (p>0.05). The number and diversity of bacteria was significantly more than what was obtained for fungi in all the soil samples. However, there was close association in the abundance of the microbes. Microbial abundance and diversity are affected when a natural forest is converted to plantation of fast growing species, so plantation development should be limited to degraded and marginal lands and such places where soil reclamation is required.
