Microbial Diversity and Abundance in Soil: Related to Plant and Soil Type

A. Meliani, A. Bensoltane and K. Mederbel
An increasing interest has emerged with respect to the importance of microbial diversity in soil habitats. The extent of the diversity of microorganisms in soil is seen to be critical to the maintenance of soil health and quality, as a wide range of microorganisms is involved in important soil functions. Since, the first estimate of prokaryotic abundance in soil was published, researchers have attempted to assess the abundance and distribution of species and relate this information on community structure to ecosystem function. Present study has investigated the linkage of specific organisms to ecosystem function and an increasing interest has emerged with respect to the importance of microbial diversity in soil habitats. The two main drivers of soil microbial community structure, i.e., plant type and soil type, are thought to exert their function in a complex manner. This review focuses on recent data relating how plant type, soil type, affects the microbial diversity and abundance of soil. Statistical analyses of the microbial counts indicated a significant correlation for bacteria (p<0.01) and no significant correlation, for fungi and actinomycetes, however, microbial enumeration indicated that bacteria were most numerous followed by actinomycetes and fungi, respectively.
