Biochar Basics

Recorded January 21, 2014. What is biochar? Horticulture Extension Agent Britney Hunter will answer this question during this presentation. Britney will also discuss biochar basics, including how biochar affects plant growth and soil health and biochar's potential benefits for Utah's gardens, farms, and forests. Also joining the conversation is Dr. Jim Ippolito, a Research Soil Scientist with the USDA Agricultural Research Service. Jim will discuss the past 6 years of biochar research from the ARS in Kimberly, ID. The talk will emphasize laboratory, greenhouse, and field observations and the positive, negative, or neutral outcomes. A significant portion of the talk will focus on research pertaining to the use of Pinyon and Juniper biochar applications to Nevada soils.

I can't believe that you are having a problem with copper, or that it is being disposed of in this manner. Maybe I misunderstood how it was being disposed of, but is a dirty/muddy solution being disposed of in the "waste pit", or is it the copper sulfate on the cow's feet that is the problem? If it is the former, then dumping it in the waste pit isn't the answer and it needs to be treated before putting it in the waste pit. You can probably pass it over lime or limestone and it will precipitate out the copper as it passes over the calcium product as either basic copper carbonate and/or copper hydroxide and the calcium will pick up the sulfate and turn to calcium sulfate (gypsum), all of which are virtually insoluble in water.
Another option would be to spray a dusting over the pit (if it has copper sulfate solution in it) of lime (calcium hydroxide) or lime stone dust and as it sinks, it should mix with any sulfate in solution and precipitate out the copper as the carbonate or hydroxide and the calcium as calcium sulfate. This will sink to the bottom where it will be "safe" until the pit is cleaned out or buried. It would be ideal to treat the solution before it enters the pit, it would save a lot of effort in cleanup.
There are other options to remove the sulfate form the "dirty bath" but they aren't as simple as what I explained above.

I really like this video. I would love to find a way to purchase a larger about of bio char in Utah County.

900C or F? for heating wallnut shells

what happens if charcoal absorbs nuclear radiation? anti-radiation or even keep radiation longer?
which if a disaster occurs all farmers must dispose of their charcoal that has been planted for decades at a very high cost.

Biochar basics
An hour long rant.

Once again over thinking and assuming. AMAZON is full of CHAR. No lab. No analysis. CHAR!
