1. Test soil

2. Analyze test results

3. Recommend treatment for soil

4. Identify common forms of the nutrients in NPK soil

5. I know I'm forgetting something...

For the testing, just follow the directions.

Know about all the crops you can fit on the page/in your head.

just to let you all know, this year env. chem. is all about soil for division B.

But does anyone know if, to practice, we need a soil testing kit? and if so, where can we get one, and what types of insturments should be included? like, how do you test for hazardous chemicals in a soil sample? and what are "digested soil samples"? where can i get som along with normal soil samples to test???

for those of you that hav ecompeted in trail events...
was the soil testing mostly test or book stuff, or did you actually have to test the soil with different insturments? and if so, what insturments were they?

Digested soil samples are soil samples that have been treated to reactants so that they are in solution (or at least suspension). So basically if they give you that they already did the extraction process for you. Or they may have just given you a solution that simulates soil nutrients, etc, without actually being made from soil. I'm hoping this is used more because solutions are generally more homogeneous than soil (and can be controlled easier) so it would make sure the playing field is leveled, and teams aren't screwed just because they got a bad bit of soil.

For division B, a rapidtest soil testing kit would probably be good. I know it was recommended by one of the coaches clinics. Unfortunately, most of the testing kits that would allow you to perform several tests on soil within a 50 minute period are rather inaccurate and not very precise as well. Hopefully, event supervisors will be able to find a way to make it work anyways (I wouldn't be surprised to see good supervisors use digested soil samples for these tests as well).
