Re: Environmental Chem
I assume you're in division B. I think you'll just get the test equipment for a simple, cheap NPK and pH test. Maybe a lab on moisture content and soil texture as well. I really can't imagine them going much more in depth with any really difficult labs in division B.
My question:
How do you modify testing for ions for soil? Can you just put the soil in water, filter what you get, and then test the soil with w/e to see if there's copper, sulfide, etc.?

Re: Environmental Chem
I would advice against it since then you have to worry about the content of the water

Re: Environmental Chem
Is knowledge of High School chemistry needed 4 this event??

Re: Environmental Chem
It definitely helps. But if you're not in a chem. course, at least look up chemicals in common fertilizers and how they're used, and common formula patterns (oxidation of metals, adding acids to certain substances, etc.) Hunt down a chem. teacher and they should be able to help.

Re: Environmental Chem
I heard that at states for division B you won't have to test stuff. My coach talked to the guy writing the test. It was really easy as long as you write REALLY good notes.

Environmental Chem...?
This is my 1st time doing EC, and I don't understand (and have no idea how to find) some of what is asked. How exactly am I supposed to "Use the results of analyzed soil to make recommendations to obtain maximum yield for different types of plants in different areas of the garden" (part 3-b) ??? ...And in part 3-d, what are the "absolutely necessary, vital, and needed in trace quantities" chemicals in? the soil or the fertilizer?
These directions need to be so much more specific, with waaayy more examples.

It's more of an informational event. That stuff, you need to look up.
I know for a fact that Molybdenum is an absolutely necessary, vital trace element needed in plants. Silicon is not needed, but helps with plant regidity.
