No-till farming is a practice that started to gain traction in the late ’70s, and has slowly picked up steam since then. Roger Claassen, agricultural economist with the USDA, says only 5 percent of U.S farmers were no-till in 1988. In 2008, that figure had jumped to 25 percent (and is likely higher now).

Take a drive through rice country this winter and you'll see that we do, in fact, have flooded unharvested grain on a grand scale. And that they'd have to shut down ag land hunting in SWLA, if it was deemed baited. Counted four different farmers "legally baiting" in the four miles between Lake Arthur and Klondike last year, and as more crawfish farmers learn the value of "green" (live) rice for oxygenation and earlier crawfish harvest, the practice will surely increase.

I know in my area no till farming has had Zero Effect on birds continuing south. As a fact, here it has had quite the opposite effect.SpinnerMan wrote:DComeaux wrote:

However, something that these guys are missing and that is well known up here. It is a major factor as to why the Canada geese don't go to southern Illinois as they used to.

The combination of the explotion of resident geese and no till farm is what caused a huge shift in the Canada geese population.
No till farming took off at the same time that the change in laws took off. So any trend would look exactly the same because they happened at the same time.
Why are the ducks only showing late in northeast Illinois? It ain't flooded corn in Missouri that's for sure. It's an unlimited supply of waste grain to our north because of no till farming.
One other thing in his trends. He includes periods of very low duck populations in the 50's. That of course will drag the trend lines down very much. He did this for sure with the Gadwall. If you start a decade later, the trend lines will look a whole lot flatter.
These are the two most common challenges of this type of analysis.
1. Correlation does not mean causation. Correlation is necessary, but definitely not sufficient.
2. When you are free to pick the bounds of the period, you will always assume the boundary that gives you the expected result - if it tells me what I already believe it must be right.
I think you do the correlation with no till farming and you will see at least as strong of a correlation as with the change in the law. There were 62 million acres of no till farming in the U.S. in 2004 and it is much higher today.
How many acres of flooded corn, etc. are there? Obviously, the cause can be contributions from both and other things.
I'm sure warm water discharges have contributed.
That's why I hunt near a cooling lake in dry mostly no-till snow-covered fields in January and typically see piles of ducks and geese as long as it has been cold and snowy enough to the north to send them down.

With no-till, you are either spraying after harvest, or planting a cover crop. Either way it leaves the waist grain unusable for birds. On top of that, Modern Machinery does not leave enough waste grain behind to effect millions and millions of migrating birds.
You act like there was no corn left before no till farming. From living where this happens, i can guarantee there is way less waste grain per acre now then there was 20 years ago. There are enough fields that they can keep popping back and forth and find enough food, the no-till practice did not change the amount of availableSpinnerMan wrote:jarbo03 wrote:I know in my area no till farming has had Zero Effect on birds continuing south.

So what are all the ducks and geese in January and February eating in the frozen corn fields up here? They aren't eating snow.
I have never seen a single field planted with a cover crop up here. The growing season is not long enough up north. It's just not done. They might chisel plow the field, but that's about it. The pick it and don't touch it until spring.
And I guess they haven't started using the modern machinery up here either because I can see the corn when setting up the decoys.
Average corn yields are around 160 bushel/acre. A bushel of shelled corn ways about 68 lbs. That's 10,880 lbs of corn per acre. Even if they modern machinery gets 99%. That means there are almost 110 lbs of corn per acre. The average field, will literally have tons of corn in it. 500 acres to 100 lbs/acre is 25 tons of waste grain in a typical field if they harvest 99% of the corn. Illinois has about 10 million acres of corn and another 10 million in soybeans. That can feed a hell of a lot of ducks. And I seriously doubt they are harvesting 99%. But even at 99.9% would still leave 2.5 tons of waste grain in a typical field.
And because it is cold and dry, the grain doesn't rot like it does further south. There are whole ears of corn laying around when you set out decoys at the end of January. Flying 20 miles gives the ducks and geese access to almost a million acres.
But, serious question, what are the ducks and geese doing out in the fields in January and February when it is frozen and snow covered? Obviously, there is plenty of waste grain there for them to eat or they would not be there. There is nothing else in these fields at that time of year and yet there they are, assuming the weather has been cold enough to push them down from the north where they obviously weren't starving. If what you believed were true, these birds would starve, but they are not. And this is the case across larger parts of Canada, the Dakotas, Iowa, Nebraska, Missouri, ...

From the 1920s to the 1960s, conservationists bred and released mallards to supplement the wild population. But those birds were of European descent, and Schummer refers to them as domestic ducks. At least 250,000 such birds continue to be released annually along the U.S. Atlantic Coast.
The influx of domestic genes has resulted in a loss of genetic diversity that might hamper the birds' ability to adapt to change. The research team is collecting DNA from mallards throughout the Atlantic Flyway to determine the relative contributions of wild and domestic mallards to the breeding population and to duckling production.

I know around here, there was plenty of grain available all winter long, way before no till. In my younger days, the river woukd be the only open water anywhere, it would load up with mallards and geese, they woukd use the surrounding corn and bean fields til they headed back north. The first downfall of hunting these areas, was when the farmer traded up to a brand new New Holland combine. Birds quit spending time in these fields. Id they were in a field on Tuesday, they would stay there til Saturday, now it's hard to see them in the same field 2 days in a row.SpinnerMan wrote:jarbo03 wrote:You act like there was no corn left before no till farming.

They used to plow it under in the fall making it in accessible. So there is vastly more available than when they deep plowed the fields.
Combined with an increase in warm water discharges. They have all the food and shelter they need. Why migrate?
And those that do get shot up for another month. Darwan would say that the odds are in favor of the ducks that migrate the least.
