Abstract:
A process for preparing an elemental sulphur-containing composition for use as a fertilizer and/or soil improver comprises wet milling elemental sulphur in a liquid to produce a micronized sulphur slurry for application to soil, and further comprises adding a preventive scavenging additive for fixating sulphur dioxide and hydrogen sulphide gases that are released downstream of the mill.
