Our friend, John Kohler at Growing Your Greens, produced an excellent video that discusses the pros and cons of building existing soil versus bringing in new soil. He discusses how to use John and Bob's to build the soil (starting about 12 minutes in). Here are a few notable quotes: "When you inoculate your garden space with the beneficial microbes, they do more than just build your soil. They also give your plants disease resistance." "The trace minerals [in Maximize] make your food taste better and make it grow bigger! And your plants will be more resistant to diseases and bugs!" "This product[Nourish] will nourish your plants, encourage microbial growth and it can reduce soil pH. It's also going to help with the bad nematodes with your soil."
