Summary

Results of experiments during three consecutive seasons on the rôle of blue-green algae in combination with partial soil sterilization and chemical nutrients indicate high responses to algae inoculation and a fertility build-up of the soil. It is also seen that blue-green algae tend to produce better response in soils which are poor.
