Abstract

Embodiments of a calcium cyanamide composition and method for their use are disclosed. The composition and method stabilize active ionic compositions comprising calcium cyanamide and enhance the effectiveness of calcium cyanamide alone or synergistically in combination with nitrogen-containing materials such as urea and organics, for example, manures. The composition and method also facilitate controllable site-directed delivery of the contents of the stabilized compositions. The composition and method are effective for fertilizing, soil amending, metal stabilizing and odor and organism inhibition. The compositions are stable, easily calibrated, and non-clogging for spray delivery to target sites.
