don't know why you'd object to bone meal, it's a readily available and long lasting source of P, and persistance is what is desireable for nutrient supplements

what are these "proteins" bonemeal lacks? or what's the difference between N and proteins? bone meal does have low amounts of N

about the only other thing that has as much P is rock phosphate, but it's not fast acting as it has less "available" P, so like bonemeal must be converted by soil microbes

Here is a link that might be useful: organic P sources

I like bonemeal also, however, if you want another organic source why don't you look into bat guano. Some variations have high phosphorus. (I think it's the "aged" variation?)

Usually people are against adding bone meal and all that stuff, in these forums, I thought, because they always seem to take the approach of "do it as cheap as possible and as simply as possible" which is good. I thought there would be easier, cheaper ways of adding bone meal rather than going out to the store and buying bags of it...No?

Adding compost is great and all but I'm not sure how to amend to provide enough phosphorus for things like my flowers....

I don't mind tilling once and starting off with amendments because that is very helpful..don't get me wrong. But after that first year, I run into the problem of "ok, how can I add things (specifically in this case phosphorus) without tilling into the soil?

Like I said, adding compost..ok..easy...and good..

but I was hoping for a nice and easy and cheap way of "laying down" phosphorus as I do compost. I guess I should just lay down bone meal the same way as I do with compost and not worry about tilling it in? And is there any other alternative to bone meal & guano?

Sorry for all the questions

I suppose I could always buy fish emulsion high in P, as well, and fertilize that way......seems so costly and time consuming though...

Rock phosphate, if you need more phosphorus in your soil. Phosphorus is one of the minerals in your soil, although there is some, 11 percent, in bone meal that is usually a calcium supplment. Most often getting sufficient quantites of organc matter into soil will help release the phosphorus that is there but unavailable to plants.

Looks like shrimp shells are a winner with a P = 9.95

:-)

many food waste items have pretty high P, like bannana skins, and if you use a fair portion of food waste in your compost you'll never have a shortage of P or K or any of the trace elements/ minor nutrients

I use both hard and soft rock phosphate. The soft RP is quick acting and the hard RP is a long term slow release type.

are rock phosphates even considered organic?

Rock phosphates are organic. That would be the the mined mineral run through crushers, bagged, and transported to you. The superphosphates are not organic because they have been treated further than that.
However, before adding any of this type of material to your garden have a soil test done to see of you need to, because adding "stuff" you don't need to your soil is a waste of your money as well as contrary to organic practices.

Well I know where I'm having flowers so I know they'll need P. I figure why not just sprinkle some in to be safe. If I get hard rock phosphate itll take a while to break down anyways, so it can't hurt. I don't feel as though I have the time to send soil for tests and wait for it. I need to do this right now.
