soil sampling questions
Hi:
My university extension center doesn't do soil samples, but instead provides a list of commercial groups that perform soil analysis for a fee (and it's kind of pricey).
These vendors provide instructions for gathering a sample which includes collection from a few different sections of the garden.
The specific 8x20 garden bed I'd like to test seems to have differing compositions - one area is quite dry, more clumpy hard clay with almost no visible organic matter, another area is a wett-ish clay with improving texture, and a third area seems to have much more organic matter in it. Part of this is because the bed is on a hill.
Do I need to do separate tests for the garden sections that have differing soil, or just take samples from each section and use the results as an "average" ?
