Abstract
Soluble, non-crosslinked polysaccharides are used to stabilize microorganisms for use as inoculants in agriculture. Preferably, the polysaccharide is alginate and plant seeds are inoculated. A solution of the polysaccharide and a suspension of the microorganism are mixed to form a composition containing about 0.005% to about 10% of the polysaccharide. The composition can be stored for one week or more before use and the composition may be dried.
