Source for "K"? ANSWERED!

[Roguejim]

I've just purchased alfalfa meal, and rock phosphate to add to my raised bed.  What is a good, preferably organic, source for potassium, that I can work into the top 4"?

Shipping for that is more than product, shop around on Amazon or local.

Ashes from the woodstove work great for K if you or a friend has one.

Thanks for the advice.  Sometimes it's still a better deal to pay the high shipping for bulk rather than paying retail for a puny box.  I'll check amazon.

A feed store will have it.

I have no idea if it works as a source, but there's an aphid spray I use that's made out of potassium soap...I would think the plants use it too as a foliar spray.

Kelp meal is probably the most important thing you can add to soil and it has more than enough K.

Blackstrap molasses. Also great for many other reasons if you grow organic. Easiest way to use is to brew a tea.

No one ships FREE.  Shipping charges are simply added to the product price.  They have everything, and it's all top notch.  But, their higher prices reflect the supposed FREE shipping.

Comfrey is another source of potash.
