Re: Happy Earth Day
I am volunteering with SOLV to plant ash trees in a local wetland today. Ash trees have a root system that contains nodes that house microbes who fix nitrogen. Nitrogen runoff has caused some major problems with eutrohpication in some of Oregon's waterways; I am doing my part to help remedy that.
Happy Earth day!

Eutrophication is a process whereby water bodies, such as lakes, estuaries, or slow-moving streams receive excess nutrients that stimulate excessive plant growth (algae, periphyton attached algae, and nuisance plants weeds). This enhanced plant growth, often called an algal bloom, reduces dissolved oxygen in the water when dead plant material decomposes and can cause other organisms to die. Nutrients can come from many sources, such as fertilizers applied to agricultural fields, golf courses, and suburban lawns; deposition of nitrogen from the atmosphere; erosion of soil containing nutrients; and sewage treatment plant discharges.
Gosh JB, doesn't everyone know that?
