Pardon my ignorance. I'm not sure what you mean by "screening a soil sample?" Can you please explain this to me?

I run the soil through a screen to remove roots grass ect. leaving a very fine textured soil. will this affect the sample in any way?

I am only familiar with the soil tests done thru CSU, so my answer is based upon the test they complete. http://www.soiltestinglab.colostate.edu/

The only part that will be affected is the reading for "organic matter." And you might want to know how much organic matter is in your soil. Plants prefer about 5% organic matter in their soil. More than that can be a problem. If there is less than that, you can add organic matter easily.

Let me know if you have any other questions.
