both have same amount of N, the fish has more P. there are no added beneficial's to either. when u say more readily available do u have research to back this up? if so i would like to read. or are you just basing that on your own experience with both? i agree cows are gross. but bone/blood meal are derived from non bovine sources. at least all that i have come across are labeled as such.^^^^right....i also believe FB breaks down and becomes available much faster overall....it also has 3% N and bennies to help it along.....IMHO, i prefer it over BM because it doesn't have any residual hormones and anti-biotics as BM does.....i think cows are gross.
this is the FBM i use...it has added microbesboth have same amount of N, the fish has more P. there are no added beneficial's to either. when u say more readily available do u have research to back this up? if so i would like to read. or are you just basing that on your own experience with both? i agree cows are gross. but bone/blood meal are derived from non bovine sources. at least all that i have come across are labeled as such.
edit: im refering to dte for both the fish bone and bone meal. and i do use the fish bone meal. i bought like 700#'s worth this year.
they say on the packages: non-bovine source. not opinion, factthis is the FBM i use...it has added microbes

in my mind, smaller bones would break down faster.....fish vs. large animals....fish live in an environment (the sea) with little gravity, meaning their bones do not have to structurally support their mass, so their bones don't need to be nearly as dense as land roving animals.......where do you assume huge volumes of blood and bone come from?....it is a by-product material from slaughter houses.....
ahhh....pressure...forgot about that.....nice......so what about small bones vs. large bones?....time to research bone density .......more research needed.....heh. that less gravity argument doesn't really work. i guess for tiny things it might, but bone is bone. osteocytes and all.
Edit: a fish that is around 20 feet deep has more pressure pushing on it than any land animal does. it's going to need a nice bone structure to support that pressure.
Does bone density really matter since the bones are pulverized into a powder?ahhh....pressure...forgot about that.....nice......so what about small bones vs. large bones?....time to research bone density .......more research needed.....
