I just talked with our son who grows in our garden too. He likes the idea of using good nematodes, adding organic materials, and growing a winter cover crop - as well as building raised beds as we can afford to. I need to talk to my wife about these ideas a lot more.
I also called the local Johnson county extension office. I'll pick up a soil kit there tomorrow and mail off the sample to Texas A&M. A local master gardener is supposed to call me later today to talk about RKN.
