Could someone recommend a source for a water soluable Potassium nitrate? I've called Lesco, Andeson's and explained that I need Potassium nitrate rather than potash derived from clorine. It's hard to make them understand that all potash is not equal. I've pulled up so many labels that my eyes are blurry.
Thanks,
Roy

Potassium Nite is actually made in Norway and sold to Israel who then has Norway ship it to the USA in their bags. Right now it is in short supply. SOP is also in demand but cheaper than Potassium Nite. It has no Chlorine.

BTW all percentage Numbers on a Fertilizer bag are Guaranteed Minimum except Chlorine which is a Guaranteed Maximum. A bag stating 2% Chlorine may not have any Chlorine.

Miller Chemical has some very high quality potassium nitrate based blends. They are primarily marketed to the greenhouse & agriculture trades but because of the very low salt, there are many uses in the landscape.

I get my greenhouse grade potassium nitrate from UAP. It is a fine powder that does not have any insoluble trash in it. It is intended for hydroponic solutions and use through injection systems. Except for the pesticides, much of what I buy and apply is actually fertilizers intended for greenhouse and hydroponic use. In your area, I would source solubles through the supply houses that work with nurseries. I should be so fortunate that the UAP branches in Hawaii also need to service nurseries. So soluble fertilizers are always available. It is just that I am the only LCO in Hawaii that uses them. Some of my loser aquaintances are always asking me to make solutions for grow room Maui Wowie. Forget it, if enough of that goes on, I can imagine solution grade fertilizers becoming extremely hard to get.

You say Pot Nite BLENDS??? Are you saying they are not 13.75-0-46. I am not familiar with Miller Chemical.

My cost of Pot Nite is now 150% of just December's prices and 250% of just a few years ago. I have an Excel spread sheet set up to calculate cost per thousand and cost per acre of each product. I just enter the current price. Sales Tax is even added to the cost. Little did I know when I wrote that program, How much I would use and need it.

I wouldn't mind having some of that for my tomatoes. Since the hurricane blew away my nursery that is about all I grow anymore. I believe that blend could be a stand alone fert for tomatoes.

Ral,

I have some 0-0-50 from Regal that I believe is stated as maximum 2% chlorine based. I will look when I get home today.

Thanks G:
I can get soluable potassium nitrate at $50/50lb bag--not that bad. And, I have another soluble 23-0-23 thats great. I have a couple of lawns that have thin turf and would like to give them a little boost to thicken.
Let me know.
Thanks again
Roy
