Abstract: Soil biota  plays an important role in  soil formation, soil development, organic matter decomposition and in soil structure formation.On decomposition of organic matter they free up nitrogen, potassium and phosphorus which are primarily nutrients for plants in crops field. Biochemical activities of soil organisms help in cycling of various nutrients in soil, improve physicochemical properties of soil, water regime and hummus availability. They are acting as a driving agent within food webs for releasing, transformation, relocation and storage of elements throughout the ecosystem by several biological activities.

    Qualitative research approach has applied in study on the effect of soil biota on physicochemical properties of soil.In this research paper primary and secondary data has collected by different sources vizsubjective opinions, real-time field observations, already existing written materials such research articles, literature review , textual data etc. has been  collected, analysed and reviewed.

    This paper, briefly highlighted some of the biological functions of soil biota, there interaction, effect and importance to improve soil physicochemical properties under sustainable soil management activities in agricultural production. This study would play an important role to establish natural farming, sustainable agriculture practice, food  quality and soil environmental health, at global aspects.

Keywords: Soil biota,Soil physicochemical properties, Soil organic matter , Nitrogen fixation, Soil biodiversity.
