[GreenYes] RE: The FTBOA-Global Green project horse manure [horse manure incineration]


Besides the nitrogen issue, we have a problem in my county with excess levels of phosphorus in the soil from the manure of some 125,000 head of dairy cattle. The plants can't use it all, but benefit from the nitrogen and organic material from the manure. The excess phosphorus washes off the land into our streams and lakes and causes excessive growth of algae and lake weeds. We are known as the Four Lakes region due to four large lakes around our main city, and are trying to improve their water quality. For the last 2+ years, my main task has been to try to come up with a better solution to this problem and it is a challenging issue.
 
It's a bit off the main focus of this list, but if you or someone else you know wants to see what we are looking at, our web page is at http://www.danewaters.com/management/ManureTaskForce.aspx
 
We also invite any comments on our work or other potential solutions. So far, we have not come up with things that look particularly promising.

Subject: [GreenYes] Re: [horse shit incineration][GreenYes] The special beauty of the FTBOA-Global Green project horse manure [horse shit incineration]

Manure has become a sticky subject.  Regulators and environmental groups have taken considerable interest in protecting surface and groundwater quality from the runoff impacts of manure from dairies.

 

In California’s central valley, the Water Board has new requirements for dairies that will be phased in over the next five years.  There will be a manifest system for any manure sent offsite.  If manure is reused onsite (applied to agricultural fields), an elaborate calculation has to be made to determine if it is being applied in agronomic proportions (more nitrogen/nutrients not applied to lands than will be taken up by the specific crop).
