Production and application of an aircraft spreadable, cyanobacterial based biological soil crust inoculant for soil fertilization, soil stablization and atmospheric CO2 drawdown and sequestration
Systems and methods are described for the production and application of a cyanobacteria based biological soil crust inoculant for soil fertilization, soil stabilization and the drawing down and sequestering of atmospheric carbon. Inoculant is generated as a dry granulate that can be stockpiled and spread onto soils using standard agricultural spreading practices employing aircraft, ground equipment and irrigation systems. This inoculant will have particular application in stabilizing agricultural and arid land soils to limit their erosion, increasing soil fertility by fixing atmospheric nitrogen and providing nutrients, and drawing down atmospheric carbon dioxide by stimulating the growth and propagation of these biological soil crusts and their associated microorganisms and vascular plants. The effect of this carbon dioxide draw down will further the broad scale application of the soil crust inoculant by industries and nations interested in offsetting their anthropogenic carbon dioxide emissions while increasing the fertility of their soils.
