Abstract: Soils are made up of organic and an organic material. The organic soil component contains all  the  living  creatures  in  the  soil  and  the  dead  ones  in  various  stages  of  decomposition.  Biological  activity  in  soil  helps  to  recycle  nutrients,  decompose  organic  matter  making nutrient available for plant uptake, stabilize humus, and form soil particles. The extent of the diversity of microbial in soil is seen to be critical to the maintenance of soil health and quality, as a wide range of microbial is involved in important soil functions.  That ecologically  managed  soils  have  a greater  quantity  and  diversity  of  soil  microbial.  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. The fact that in some situations the soil and in others the plant type is the key factor determining soil microbial diversity is related to their complexity of the microbial interactions in soil, including interactions between microbial and soil and microbial and plants. 
The  basic  premise  of  organic  soil  stewardship  is  that  all  plant  nutrients  are  present  in  the soil  by  maintaining  a  biologically  active  soil  environment.  The  diversity  of  microbial communities  has  on  ecological  function  and  resilience  to  disturbances  in  soil  ecosystems. Relationships  are  often  observed  between  the  extent  of  microbial  diversity  in  soil,  soil  and plant quality and ecosystem sustainability. Agricultural management can be directed toward maximizing the quality of the soil microbial  community in terms of disease suppression, if it is possible to shift soil microbial communities.
