I have two still growing at about day58. I experimented this year by using synthetic fertilizer on one and not the other. Now I'm tempted to try a little 00-00-52 on the au natural one. Both are slowing down to8 lbs a day approx. the "natural" is already out taping the others by 100lbs. Am I just wishing to much? Both are personal best by 200lbs. jr

synthetic high potassium fertilizers will stop your pumpkin in its tracks. i know a guy near me that had an 805 pukos heading for 1000 pounds a few years ago and thought he needed to push it with some 0-0-60. slowed to a crawl and was all but done a week later. i only use fish and seaweed this time of year, or plain water.

0-0-50 is sulfate of potash which is now classified by OMRI as a "natural mineral" when reacted or as "organic" when obtained from brine shrimp. No matter. SOP is very low salt so if it is properly used will pose no risk.

0-0-60 Muriate of Potash is also known as Potassium Chloride or KCL. I sell a lot of KCL...as a deicing compound in the winter. In most cases I would NOT recommend using KCL in the patch.

Steve: Is 0-0-50, sulfate of potash, the same as K-sulfate? k-sulfate solution that I have is 6%. I've heard that k-sulfate solution cannot go over 6% since it will crystalize at higher concentrations. ???

I'm not familiar with the trade name "K-sulfate". Potassium sulfate (or sulfate of potash or K2S04) probably would crystalize in water if much more than 6%. Most potassium sources will salt out if they're blended with certain other minerals. That said, potassium thiosulfate is 0-0-25 & Agro-K's KDL (potassium carbonate) both remain fluid.

Agro-K has this nice 0-0-6 which is K2S04 blended with seaweed.

Is this what you have?

WE HAVE BOTH IN STOCK-- KDL> 0 0 24 AND ORGANIC> 0 0 6 Both have seaweed in them thanks Steve--craig

Sorry Steve. I've been off the computer for a day or two. The potassium sulfate I have is 6% potassium sulfate solution. No additives. I guess it's different than Agro-K. I don't use seaweed at this point in the season because.. .well, I can't afford it and, I've been thinking seaweed is mainly good for trace elements and minerals and it's late in the season so why use it now? Isn't it a better soil ammendment anyway? Oh well. Thanks for answering my question. All this work will pay off! Best wishes, Greg

Greg,

Use what you have there. We never want the potash reservoir to dry up at this time of year. Did you soil test give you potash concerns?

Steve. Looking at a soil test? Ha! I skipped that this year. Ok. Before, I hear the brow-beating from everyone, let's reason this one out. I figured my soil ain't really that much different than last year's. I mean, soil changes really slow. I had a soil test done last year and the soil was super-charged according to the soil scientist. The only thing that I found from experience is early season N and late potassium since I had over-loaded the soil with Ca. I guess I would add potassium even though I had a soil test that told me I was ok. I mean, half the potassium is locked by Ca and my pH of 7.1 might lock some more. I can't be too wrong adding potassium? What do you think?
