Hey Ryan, I prefer to use Logan Labs for my soil testing needs. I find their soil analysis to be more complete than others that I've paid for in the past. For example, I have gotten some soil tests done by the Ut ag extension, and their test and soil extraction method did not provide Cation Exchange Capacity, which is important to know as it tells the holding capacity of certain nutrients in a soil, and their test also did not provide copper information. I find that Logan Labs test to be easy to interpret and I think the price is fair for the amount of data they provide. While I have never used the home
soil test kits, I question the accuracy of some of them, and for me I just would rather send twenty five dollars off in the mail and have my soil analyzed by a lab with million dollar testing equipment that will provide very accurate results.
