Will you change??

[agchat]

After reading the Western Producer this morning, and thinking probably that most on here do get it, here is my question.
After reading the article on grain aeration, in 7-8 months when it comes time to flip those fans on, will you make the change, or do you really care? Do you agree with the article, or will you argue his facts? If you disagree, then what points do you disagree on?
OR, do you even give a rats ass, and just keep doing what you have been doing for years?

Do you have a link?

Change what?

After hearing Palmer talk last year at IHARF meeting, I tried aeration at night this year. Seemed to work well, but not enough crop to give it a good try. The logic is there, but totally against everything we have ever been told about aeration.
No one has ever done a study like this.

It starts on front page a western producer, then Kevin Hursh also talks about it in his column

presentation will be on iharf.ca eventually. Not there yet.

I have not read the article yet, but someone mentioned airing at night? Maybe I live too far north but my advice if worth anything and from experience is turn the fans off at night. Unless you get a dryer night which is not very common one would be adding moisture to the grain. Kinda defeating the purpose. I have had no ill effects from turning fans off at night, with the occational all nighter.

Hopper I agree we do the same for Airation
Turn off at night on in day. But the Grain
dryer is better.

Thanks for the link charlie.

It makes sense to me. Can anyone say "paradigm shift?"

My brother has a masters of engineering degree in
fluid dynamics,i'll get him to explain why or if its true.

I am not very sure about this at all.
Where did they do this test, Indian
head? Which is not really dry nor wet
area, I suppose... hmmmmm... The idea
that on a warm moist night, that the air
holds little moisture is bizarre. I
would say half the nights here are
foggy. I fail to see how running fans in
fog when the "air can hold less moisture
due to it being cool" could be helpful.

Or maybe I am a throwback.

Most guys aerate to maintain condition
anyway, drying is a bonus.

I think I will stick with warm dry days,
and leave the wet sticky nights to the
owls!

Actually.... if you reverse engineer this bitch we could
start adding moisture to grain to make more money
in the elevator instead of selling them super dry stuff
all the time.

thinkin the same cotton - 10% wht and 6% canola is lost money...

"For example, at 27 C the air can hold 4.3 kilograms of water; at 50 percent relative humidity it is holding 2.15 kg of water."
Very confusing info. What is RH at 27C? What is temp at 50% RH?

"But cold air has less capacity to hold water. So a higher relative humidity, say on a cool night, actually can mean less water in the air than during the hot day."
The issue is the moisture in the grain, hot air holds more moisture therefore removes it from wet grain.

"The moisture carried in that hot air collides with the cold grain and is released into the grain."

Grain usually warm in the fall, almost sounds like the fan is running in May when grain is near zero.

"Even on a hot, humid summer night, the amount of water in the air is actually small, Palmer said."

We have cool humid nights, a hot night is rare. The RH usually 90% plus.
