Composting Poultry Offal. The objective of this project was to develop a successful composting process of poultry offal to produce finished compost that is environmentally sound, economically feasible, and returns nutrients to the farm. Compost was made with materials produced on Lopez Island and was compared to compost made from traditional composting materials that were imported to the island. Efficacy of composting as well as costs were compared.

Cover Crop Research

Organic Fertigation. A study was conducted at WSU Mount Vernon NWREC to provide a cost analysis of organic fertilizers that can be used for fertigation. In addition we conducted a field study to compare three fertigation application rates for three crops, lettuce, broccoli and pie pumpkins. This is a report of our findings for this study that was conducted in 2009.
