Is it true that corn gluten meal attracts more earth worms, thus increases the amount of worm castings?

 

all the better.But probably not in large quantities.

 

Chances are corn gluten meal is going to do very little as a weed preventer. Whether you apply early or now. It's pre emergent properties aren't great.

 

It's going to smell. But other than that it should help the microbe population, I wouldn't even think of it to replace a pre emergent.

 

You're right, options are limited in Ontario. But that doesn't mean there aren't options available in the US.

Dimension 2EW is a preM that I know is labelled for dandelions. Prodiamine will not prevent germination.

to clarify I am only looking at it for dandelion Prevention. nothing else.

Do you mean that invite help but only to a very limited degree? corn gluten meal ismarketed to prevent dandelions and crabgrass. those of the only two weeds that are marketed

given that I'm only looking for dandelion, will still work or also still limited. If it would work by my too late?

yeah hearts. I want to try to avoid the other option,Imports for the moment if at all possible. Is Pro diamine the active ingredients in corn gluten meal? I find it puzzling why corn gluten meal is marketed here if it doesn't work.Even if it's not the best choice and has some degree of success, I would like to try it To my peril.lol.

I wish there were some way that the success rate was quantified by a university/ college extension

 

It's not the greatest preventer I tried one season to be honest it probably did nothing but I will say it's a good organic fertilizer

The efficacy section is a decent read.

 

A few years back when i was trying an organic program, I read and I think i downloaded a study on corn gluten from either Purdue or maybe Iowa. I am on a business trip once home i will try to find it.

Main point: you might get some pre-emergent effect from using a very large amount of corn gluten meal. Way too much cost per 1k for very little effect. But it does make a very good slow release fertilizer just as @M32075 stated above.
