Well there are many controls of Root knot nematodes. The most important control is to never till plow or cultivate. This is because it destroys the soil structure making the predatory nematodes ineffective. (without a lot of soil pore space and structure the predators can't move). Then there are certain plants like marigolds and certain covers like cereal rye. If you use multi-species cover crops for soil health, make sure to include French Marigolds in your summer mixture and cereal rye in your winter mix. Lastly several fungi are effective nematode trappers (nematophagous fungi) and bacteria such as Pasteuria penetrans.

There are many options. I simply don't know your particular situation. BUT let me go through a few for you. One thing you could do is simply skip a season. First make a high quality thermal compost 4 parts brown 4 parts green 1 part herbivore manure turned whenever it reaches 160 degrees at the core. Once it is finished lay it 2-3 inches deep over the whole area and mass plant marigolds. When the marigolds begin to set seed, mow them and mass plant a cover crop mixture of cereal rye and sunn hemp. (and maybe a few others in the mix) Mow the cereal rye if it starts to go to seed, otherwise just let the mix grow. (you might have to inoculate the sunn hemp for best results.)

Thanks again for the help.
3 steps forward 2 steps back. Meaning yes tilling in mulch does add organic matter, but it also destroys almost as much as you gain. That's why people have to do it every year. Meanwhile tilling breaks up all those worm holes and destroys other structure in the soil needed by predator nematodes to hunt root knot and other parasitic nematodes. Remember, predatory nematodes are 10 times bigger than root knot nematodes. They can eat a lot of them, but if you till up their highway system, how are they going to even move?? That's not even counting all the trapping fungi that have all their traps destroyed when you till. Imagine the soil community like a city. Say New Orleans....with a Katrina every year? One Katrina is bad enough, but you can recover and rebuild. But every year? That's what you are doing to the soil community when you till.

Oh don't worry. I don't know anything either. The real expert is Sepp Holzer. And even he, genius that he is, never farmed/gardened in Alabama. Me neither. I farmed in Indiana and Oklahoma and learned a small amount from the family farm in North Carolina, and gardened in Florida, Idaho and Washington. Still tip of the iceberg. When I moved to Oklahoma I had to teach myself everything all over again. It's that different. I honestly don't know what legume would be the best for you. I suspect sun hemp or whatever clover grows native in Alabama. Just don't monocrop it. Use a blend and lots of companion planting. Remember, most plants actually cooperate when you grow with biomimicry instead of chemicals.

Sorry for so many questions the more I ask the more I realize that for all the years I have been gardening I still don't know anything.
