Is there any reason I cant make my own 0-0-25 foliar by cutting the strength of 0-0-50 soluble in 1/2. I have a bag of 0-0-50 soluble and if it would work I would love to use it...Tom chime in if possible...Mark

Mixing fertilizers isn't as straight forward as you would think.
I was given the long and very confusing explanation from our supplier, in a nutshell it is this:
1 lb of Soluble 0-0-50 diluted in 1 gallon of water will make a 6% solution.

I didn't ask if you could continue to double and triple the solution.
At this point, I would probably stick with the 0-0-25.

Thanks guys..I wouldn't take a risk on a mid to late season fertilizer..a few dollars saved could ruin the season..no need...Thanks..Mark

a solution is a solution....1 lb in 1 gallon is 6% of 0-0-50, add or subtract water quantities only changes the % of the solution...adding inert materials only changes the potency of the applied material...Like Tom sez change the solution and rates of application is your best bet...work with the Known quantity and go from there. a pound of 10-10-10 mixed with a pound of 0-0-50 gives you 2 pounds of 5-5-30....I'm not so sure...

Mark, this is a very interesting question. Mixing fertilizers isn't as simple as that, I got a long and very indept/confusing explanation from our supplier, but the short version is this:
1 lb per gallon of water will make a 6% solution.

Mix approx. one pound of potash in one gallon of warm to hot water. The higher the water temperature the greater the solubility.
Mix, agitate, or shake the liquid for 3 to 5 minutes. This procedure will produce 1 gallon of 6% potash liquid fertilizer.

1 lb of 0-0-50 contains 1/2 lb of potassium. 1 gallon of water weighs approximately 7.5 lbs. 1/2 lb of the resulting 8.5 lbs of mix is potassium so the mixture is 5.85% potassium or about 6%. if you mixed the 1 lb of 0-0-50 with 7.5 lbs of sand you end up with the same strength fertilizer.

A 6% solution would be equivalent to a 0-0-6 analysis.

one correction, water weighs ~8.345lb per gal.
I don't know where Amelio was going with the 800g/Kg, it's very rare that a kg of a substance weighs anything but one kg ;).

I don't know how sulfate of potash would be as a floral. I generally keep to organics (fish or compost tea) for floral feeding as I'm scared of causing nutrient burns (as the water evaporates off the leaves it will concentrate whatever you spray to some degree).

You are correct I mistook the gallons per cubic ft conversion with the weight conversion. the fertilizer analysis is baseds on weight.
