Bests & Worsts Reviews from Amazon

I grew up on a farm and I've been gardening for over 50 years. When I was a child, we took soil samples to our county agent every few years and guessed during the years between samples. That was not often enough for NKP or PH. The County Agent's report covered 6 or 8 more things such as borax, aluminum, and calcium. Those things change very slowly and only need to be tested for only every 5 to 10 years. In the fifties and sixties, we just assumed the soil would need lime each year; it was acid. However, the amount we used was calculated by rule of thumb. Others used the taste test; tasting the soil to tell if it was sweet or sour; better than nothing but very distasteful when the fertilizer of choice is manure. If you do no other tests, do this one! PH controls whether or not a plant can take up nutrients. All the fertilizer in the world will not help, if the PH is wrong. I purchased the full test set as well as this one so that I could do more frequent PH tests and in more places such as around shrubs, bushes, and trees, especially fruiting trees and bushes. I have been using these products for at least 20 years. This purchase was just to renew my supply. I can usually go 2 or3 years with a full Luster Leaf set plus an extra PH test set. Buy and use it!. It will save you money on fertilizer and you can have the best garden in the neighborhood!
