Jarrod ,it is water soluble you mix it with water as per manufacturer's instuctions.

Hmm ok, I will re read the instructions. Thanks heaps

I'm going to make my own fertilizer blend for my garden, a native garden that containing a lot of plants in the Proteaceae family, that are very sensitive to phosphorus (which takes 50 years to break down in soil). As bonsai, these plants don't care as much, because the proteoid roots (roots that are very effective at picking up elements, particularly phosphorus) can be pruned off when repoting, and sufficient levels of phosphorus prevent their production after that. This is not the case in the ground.

So, im going to fertilize with urea (47% nitrogen, or there abouts), potash (very high in potassium) and trace elements. This will provide EVERYTHING a plant needs except the phosphorus that i don't want. I will not use the urea straight, but dilute it with large amounts of water. Same with the potash, and trace elements.

Whats this got to do with you? Well, you could effectively choose the NPK you want! Get it down to whatever decimal point you would like ( e.g. 6 : 2 : 5.2347854275435672834783247564375128374 etc) and achieve ultimate satisfaction. Or you could just use any of the existing products. If there are available quantities of each macro and micro, i doubt you will have any problems. Just a thought!

Thanks Jayc, makes a lot of sense.
