The present invention relates to methods for producing microbial preparations for crop production and microbial preparations produced through such methods. The formulations contain microbial inoculants like Azospirillum spp. which are grown in a complex medium, lyophilized with powdered milk and further supplemented with minerals and vitamins, starch and inert substances such as talc, chalk and diatomaceous earth. The products manufactured by such methods have shelf-lives of more than 3 years. They are used to inoculate seeds, seedlings and planting materials among different agriculture and forestry species for enhancing root, root hair an shoot formation, enabling plants to efficiently use soil nutrients, supplying plants with nitrogen from the air, tolerating drought and protecting plants from root pathogenes. |
