Too much phosphorus, mainly, which apparently keeps the plants from absorbing any other nutrients. (5x too much phosphorous) I think that was from too much goat poop. ( I thought it was going to be good for the plants) I was unable to find any kind of quality garden soil that wasn't mostly sand, or compost, both of which I have plenty of. ( I live on a sand hill and don't need to buy more sand) so I've been purchasing bagged garden soil, and mixing it with my soil 5 parts to 1. This year, it seems like what I've planted out there is growing fine. Even the strawberries, which previously just sat there and slowly died.
Strawberries
Summer squash
Tomato
Onions
