Hi Van: We aren't too far east of Devils Lake. The lake is approaching the levels of the last wet cycle during the mid 1800's. It is drier this year, but not a lot drier. Less Prevented Plant, but overall the crops are late.
Devils Lake will stay high for a few more decades, then start its slow retreat as the wet cycle comes to an end. The central corridor of the US has an 80 year pattern of wet/dry.

This article may have relevance to Ag questions, and is worth a look: "Plants have unexpected response to climate change" news.sciencemag.org/climate/2014/08/plants-have-unexpected-response-climate-change"Not all species flee rising temperatures. As the mercury has inched upward across western North America over the last 40 years, many plant species have moved downhill, toward—not away from—warmer climates, according to the results of a new study. The finding adds to growing evidence that temperature isn’t the only factor influencing how Earth’s life will respond to climate change." My suggestion - the plants know what is coming, and follow Astromet!

My suggestion - the plants know what is coming, and follow Astromet! But there is also the effect of increasing CO2 levels which reduce the effect of heat stress on plants. Google - Plants Heat stress CO2 OR "carbon dioxide" You will receive multiple papers showing that CO2 reduces the impact of drought and heat stress on plants. This is one of the reasons the 'deserts are greening'. It is a pity these 'scientists' are such one-club-golfers, it really makes you wonder at the state of the universities these days.

Interesting. So plants, where water transpiration is proportionate to CO2 concentration, respond to the higher water loss necessitated by higher CO2 levels by reducing the number of stomata. Resulting in lower water loss. This prejudices their thermoregulation and to cope with a need to dump heat when stomata reduce, plants migrate to lower temperature zones. That would be expected - but is not happening in all cases.
Looks like several boxes restricting sight in the scientists!

Sig,
From the looks of things, Fall in the Western Great Lakes area will continue to be ground zero for much below average weather. I believe crops in your area are behind schedule a bit as for how far into the season we are. If you could generally explain:
1. How much cushion farmers ordinarily have between first frost, and crop ability to handle a frost. ( I know, not well put, but I hope you understand what I'm asking.) 2. How much of that cushion is left? (How far the crops are this year as opposed to average.)
Thanks

dontgetoutmuch: Normally, 10-12 days cushion between maturity and 1st killing freeze. That 10-12 days requires normal planting dates. This year, we did not experience normal planting dates, we were 2-3 weeks behind.
2. The wheat here will be ok. Lateness becomes a harvest issue as putting damp straw through a combine is difficult. Corn....generally in NE North Dakota the corn needs 50+ days from today. That puts it slightly into October. Soybeans...they are daylight sensitive, so much less subjective in regards to freezing. With that said, they are still blooming, so need at least 40 days of frost free weather to achieve an acceptable yield.
What can change some of this? Currently, in a somewhat large area it is dry. Dryness accelerates crop maturity, but in doing so robs yield.
Did that help at all?

Do the wheat farmers use swathers in your area? Most of us don't anymore. However, if a field is varied maturity because of rains, or poor stand resulting in weedy areas, the swather may be pulled out. I have one quarter that I may swath. It was seeded in 3 different time frames(between rains this spring), and the last 8 inches of rains produced some localized down out along with a thinner stand so there are a few weeds. Forecast looks wet tho, so might go with Roundup, but I really don't like using that stuff as all research is now pointing to roundup being a chemical that does do something in digestive tract long term. It isn't the GMO part of the crop, it is the actual chemical.

On the bright side September is still looking warmer on long term forecasts that I have seen. Of course if it turns out to be warmer then average or just warmer July/August remains to be seen.

Kochia, yellow foxtail, pigweed are the main escapes in the lower areas.

I will try and get a photo next week. Round up sterilizes the seed, even tho it may not kill the plant.
We do not have a lot of kochia resistant plants here yet, but we all know it is coming.
I don't like to use Roundup, as I don't want to put a chemical on my wheat that I know is going for human consumption. But in a pinch I will, as it is a cleared option. Still don't have to like doing it tho.

I don't remember the thread where you guys were posting pics of old case or IH tractors, but I thought you might like to see this good old workhorse, a 1956 IH 300 Utility. Used it just today, runs great.

Walnut: Does it have live PTO? We had F-20's, H's, M's, 450D, 706, 966, magnum etc.
I have been looking for a utility tractor with a 3pt hitch. Dang little things are expensive!

It has live PTO and the fast hitch connectors which I kinda like just cause I already have the implements, glad I don't have to buy them after the fact. I also like its slightly lower center of gravity for the generally non-farm stuff I do.
