I should know the answer to this but I don't so I'm looking for some help. This is my first year in this garden plot. It's an old garden site which I reclaimed this year. I noticed a lot of crown vetch ( a legume) which led me to believe the soil was decent. Soil life is also good but the soil is a bit sandy. Now that the plants are up, I'm noticing alot of leaf growth but less of a production of pea flowers then I'm used to. I not going to get a normal yield. It looks like I have way too much nitrogen. I know if you pile on lots of fresh grass clippings it will remove nitrogen as it decomposes but so I've done that but it's not going to help me with this crop. Creepy guy next door #1 (yes, there is also a #2) fancies himself to be an organic chemist but all his suggestions are geared to fixing in more nitrogen, not removing it short term. I'm upping the P and K but it's still out of whack. Any suggesting on how to flush nitrogen out of my soil?
