Sulfur Supplementation

Just wondering if anyone has tried experimenting with adding a small percentage of sulfur in their gardens? I was doing some reading and apparently in the past some fertilizer companies were marketing sulfur as the 4th macronutrient with an n-p-k-s ratio. Although it didnt take off much in the open market, and eventually died out, there have been recent studies working with other angiosperms claiming that sulfur is close to or more abundant than phosphorus in some plants and is necessary for proper yield. If anyone has played around with this or has some light to shed on this please contact me as i'm very interested in this. Here's one of the articles I found that gives a decent synopsis. Peace and love guys

Dilly,
I've used it mostly as a means of keeping soil acidic. Micro-organisms gradually convert it to sulphuric acid and so it's especially useful for acid loving plants like blueberries and ganja...and should be especially useful for Blueberry ganja! lol

Epsons cleared up any sulfur deficiency I've had...just throwin that out there

Gypsum is also good without messing with the pH.

There is also So-Po-Mag, but no experience with it, I add gypsum to my soil mix.

What a lot of people don't realize is that epsom salts actually provides more mass in sulfur than it does in magnesium.

I've wondered before if the level of sulfur during flowering can affect the smell of the final product. I know there's a certain type of onion grown in sulfur deficient soil which doesn't make people cry when they cut it. (i never cry)

S is definitely no 4th. Calcium is easily the 4th abundant and necessary element after N P and K.

This can be easily misinterpreted. The level of P is often stated in ppm or uM on analysis, but NPK is actually a measure of phosphate P[SUB]2[/SUB]O[SUB]5 [/SUB]content, which includes a lot of weight in oxygen.

Plants want between 30-60ppm of P (not phospahte, but P), sulfur by contrast is usually between 30-60ppm as well.
