CORVALLIS - The Oregon State University Extension Service has published a new, 12-page report that focuses on how biosolids can be used to supply nutrients to crops.

Topics covered in the report, "Fertilizing with Biosolids," include: the nutrient content of biosolids, techniques for converting nitrogen availability to application rates, effects of biosolids on pH and soil quality, heavy metals, crop yield and quality, forage quality, site approval for biosolids application and frequently asked questions about biosolids.
