outdoor soil nutrients

hey guys looking to see what nutes are good to add to the soil before planting, my plan so far is

horse poop and rich fluffy organic dirt from the barn at my house..

i do not want to add any nutes at all for the whole season "if im able to" i plan on also using those water crystal things so i wont need to water all the time..

i was thinking of grabbing some all purpose fertalizer 10-10-10 there small round balls of nutes.;... but im not sure if its a good idea so any tips would be good...

also looking into blood/bone meal????

ive used mg 10-15-10 last yr with good results but i dont want chemicals this yr


any info would be good because all the nutrient stuff i find is for hydro-ponics not soil
