Considering Biosolids as a Sulfur Nutrient Source

Understanding the sulfur (S) value of biosolids produced by various processing methods is important for growers who routinely apply biosolids to crop production fields and rely on the S to support optimal plant growth and crop yields. It can be challenging to determine though since S is typically bound in organic and mineral compounds that are either mineralized or dissolved over a period of several months or longer after coming in contact with the soil. The goal of the research described in this article was to determine how processing method and biosolid properties influence S availability and fertilizer value through lab incubation.
