Many Army land managers find stabilization, rehabilitation, and revegetation of soil to be extremely difficult on fully denuded lands andor those riddled with rills and gullies. Finding a suitable and affordable way to repair these disturbed lands can be a formidable challenge. For arid and semi-arid lands, a well-developed cryptogamic crust may, in many cases, be an appropriate foundational material. The objective of this study was to incorporate cyanobacteria into a pelletized starch matrix for use as a soil inoculant in arid land rehabilitation. Two common terrestrial cyanobacteria, Nostoc punctiforme and Microcoleus vaginatus, were pelletized and monitored over an 8-week period July to August, 1996. Escapability and viability of the pelletized cyanobacteria were tested using both chlorophyll a extraction and epiflourescence microscopy. Direct counts of populations and mean levels of chlorophyll a in both species steadily declined during the 8-week period. Results were poor and indicated this approach would be ineffective in the field. Dessication of the organisms during the pelletizing process may have been a prime reason for lack of success in this study.
