Correct me if I'm wrong. Worm casting are high N and it contains ALL the trace elements that are added to supersoil. Right? If worm castings do not burn you plant and contain all the trace elements, why use amendments? Can a person use only casting and do well? Why amend the soil if the casting have everything?
I dont mean to keep asking lame noobie questions!
nah, worm castings are relatively low in most NPK, you use them for the beneficial microbes.
using ONLY worm castings as the sole amendment and you'd be growing some unhappy plants.
low in everything, but VERY important to use, as it adds a LOT of life to your soil, but for amendments you'll need more
fish bone meal, manures, alfalfa meal, some like blood meal, bat guanos, seabird guano, etc.
