Well the last round of snow melted off of my beds to I took the opportunity to take soil samples. I was raised in a wonderful gardening environment down South (deep, rich soil, 10-month growing season, plenty of rain....ah I realize now I spoilt I was), but this is my second year working on a bed in Montana and, well, things are a bit different. It's still 5 weeks till the last reliable frost, and my early tomato seedlings are about ready to be potted up. Anyway, toward the end of last season I started so see some yellowing on the older leaves of some plants. I suspected a nutrient deficiency but didn't act on it as I was travelling a lot that summer. I took my soil samples yesterday and ran a pH/NPK test, and sure enough I have excess phosphorus and potassium, but absolutely no nitrogen. Armed with that knowledge I'll be adding some dried blood to my usual compost & manure ammendment, and at the end of the season I'll let the chickens clean up the beds for me without worrying about nitrogen surplus.
I also found out that my pH is even higher than I suspected at about 8, even though I added a good bit of sphagnum moss last year. I blame the well. So, I'm thinking a dose of ammonium sulfate to bring it down quickly, plus regular coffee ground sprinklings to act more slowly and counteract the water. Hopefully this will all happen in the next week or two, so then I can set out my broccoli, bok choi, onions, and a round of radishes under cold frames.
