Use of indigenous n2-fixing cyanobacteria for sustainable improvment of soil biogeochemical performance and physical fertility in semiarid tropics

Objective

Two major aspects of the interactions between indigenous cyanobacteria inoculantsand degraded soils in Semiarid Tropics will be analysed: l) the influence of N2 fixing activity on soil biogeochemical performance (nutrients status, OM content and turnover etc.) and 2) the role of secreted exopolysaccharides, for improving soil chemical-chemical properties and reducing adverse physical processes such crusting, clay dispersion, erosion etc. The most suitable protocols will be established for enabling small rural communities to grow a selected strains of indigenous active cyanobacteria. In each Daces a selected team of local farmers will be trained and instructed on how to manage and maintain these simple culture systems and on how to spread the cyanobacteria in the field. Models will be developed to predict the short and long-term effects of such practices on overall soil fertility and productivity.
