Multiple-function biological compositions for the biological control of phytopathogens, phytonematodes and agricultural pests are provided for use as an inoculant, for phosphorus solubilization, for soil conditioning, for use as a biostimulant, for hydric stress reduction in cultivated plants and for bioremediation in agricultural or non-agricultural areas. The compositions contain mixtures of additives and excipients having at least two genera and/or species of Actinomycetes or other bacterial species, so as to provide nematicidal effects, fungicidal effects. insecticidal action in the reduction of damage and control of insects, and other properties such as growth-promotion and soil conditioning. The compositions may also be used, for use as a biostimulant, for hydric stress mitigation in cultivated plants, and for bioremediation in agricultural or non-agricultural areas.
