| Cattailking - 8/6/2023 21:00 Absolutely it’s pulling from deep down, just as anyone who is complaining about “only” getting a half inch over the weekend. Unless it’s dead and brown from top to bottom it’s getting moisture somewhere, could be 8 feet deep, but it’s getting it from somewhere. I guess my point is unless your crop is totally dead a half inch is still beneficial. I have seen those charts 1000 times and don’t believe them for a second. While corn “could” use that much rain it doesn’t have to have that much. By that charts map we’ve used 17-20 inches of water. It has rained 5 inches. Does that mean our soil had 12-15 inches worth of rain sitting in it? The answer is no, we were on the dry side going in. So why isn’t the corn dead yet?
If you have roots 8' deep I wouldn't doubt that you could have had 10-12" of water in your profile. With a name of "Cattailking" I doubt you're farming sand/gravel hydroponically.
Most extension soil moisture testing only goes down to 5' and many soils are capable of holding 10-12" in the top 5'. When you're dry, getting roots down to the moisture fast enough is often the problem.
For many that are saying 1/2" isn't gonna do much, their corn is turning brown up to or above the ear leaf. 1/2" just prevents the inevitable that the plant is gonna shut down entirely, real soon.
Also, those charts are for growing a good corn crop. Yes, you can grow sub 100 bpa corn with a lot less water. If you want to grow 200+ it needs water from somewhere.
