Q: I have 4 disctinct areas around my house where i'd like to test the soil. does this kit have enough to test all those areas?

"40 tests" means that it has enough materials for 10 tests each for pH, N, P, and K.

Q: Where can I get the replacement chemicals and how much do these cost with shipping and handling?

I've looked everywhere and you can't find any replacement chemicals for this set.

Q: If used properly, is there enough reagent (solutions) to conduct the claimed amount of tests? Many complaints about how many tests...

There is not enough solution to do the number of tests claimed. The pH test solution appears to yield a result consistent with my pH probe. The remainder of the tests yielded no results, ie. there were no color changes present to compare against the chart on the nitrogen or phosphorus tests, there was no cloudiness detected on the potassium test. These results were inconsistent with prior soil testing and my crops show no signs of the deficiencies that would be present if the tests had been accurate. I had purchased this test kit in 2014, I think, and it had appeared to work accurately. The kit I purchased in 2017 performed completely differently. I won't be buying this kit again.
