Struvite as a Phosphorus Fertilizer Source for Greenhouse Crop Production – webinar

This webinar highlights recent research by Rita Hummel of WSU on struvite as a phosphorus source for greenhouse production of bedding plants and vegetable starts. Her research includes struvite derived from municipal wastewater and dairy manure. Craig Cogger opened the webinar with a brief overview of the phosphorus challenge. After Rita’s presentation of greenhouse research results, Keith Bowers discussed struvite production as one phosphorus removal technology for wastewater at livestock, food processing, and public sewage treatment sites. The webinar closed with a brief summary by Craig and an open question period.

Creating High Value Potting Media from Composts Made with Biosolids and Carbon-Rich Organic Wastes

Organic Waste to Resources Research and Pilot Project Report. Hummel, R., C. Cogger, A. Bary, and B. Riley, May 2010. Ecology Publication Number 09-07-069. Composted organic waste including biosolids may substitute for potting soil for nursery uses. This study found that composted organic materials can perform as well as typical peat-perlite potting mixtures.
