Re: Re[2]: Organic Fertilizers

Shawn:

It has always been my understanding that bonemeal is available to the
plants the first year it is used. It is not as quickly available as
chemical fertilizers. It is also my understanding that the use of organic
fertilizers in general require a good organic soil. (compost and such)
The microorganisms that are active in breaking down the organic
components of your soil also break down the organic fertilizers to the
point where they are available to the plants. As far as phosphorus
sources are concerned the only one I know of that takes years to
completely break down is rock phosphate. It also serves the purpose of a
soil ammendment to improve the tilth of your garden.
