Summary : Soil functions which refers to diversity and activity of living organisms are often modified by modern high-intensity agriculture. Global nitrogen economy has been changed by synthetic nitrogen fertilisers use and biological nitrogen fixation is less and less valorised. The soil biological potential and its implication in global soil fertility are minimised by massive utilisation of chemical fertilisers and pesticides. In a next future soil quality couldn’t be evaluated without an appreciation of biological properties. Conceptual and methodological approaches involved in soil biology will be useful tools in complement of traditional soil analysis. Management of the interactions in the rhizosphere which is a unique environment where plant root and soil microorganisms meet together is a way to better use of the soil biological potential. |
Keywords : nitrogen, nitrogen fixation, soil, biological soil quality, organic matter, rhizosphere. |
