Soil problems HELP!
I'll start by saying that I am fairly new to gardening. About a month ago I tilled my new plot (incorporating 8-8-8 fertilizer) then planted onions, potatoes, lettuce kelp, and several other things. The only thing that has started to come up is the onions. I dug up one of my potatoes and it looked just like it did when I planted it. I called my local county extension office and asked them what type of fertilizer I should be using. The gentleman that I spoke with recommended that I do a soil sample, which I did. He guessed that I would be low on nitrogen, phosphorous and have a high ph. He was exactly right! My nitrogen and phosphorus didn't even register on the test kit and the PH registered as high as it could measure. I live in the Blackland Prairie region which is known for being an alkaline clay but the lack of nutrients such as nitrogen and phosphorus surprised me. There is a ton of agriculture in this area. Cotton and soy fields surround my neighborhood. I sprayed Miracle Gro Garden on my rows and also put out a little more 8-8-8 fertilizer and watered like crazy today. What else can I do that is a quick fix for my problem. I don't have any compost and I really don't relish the idea of re-tilling and starting over. I know I will certainly incorporate compost before next season, but am I out of luck for this year?
