Copper and boron

[brs]

Did 32 soil samples on a quarter section to see variability throughout the field and on soil tests average copper was .4 and boron .3. Which products is there to use that are good bang for the buck and easy to apply would like to correct this deficiency

Once put 500lbs of copper sulphate into the canola tank while doing wheat. Was shooting for a few pounds an acre. Stuff ran right through the rollers was all gone in 5 acres. Never showed up on the combines yield monitor that year or ever since.

How do you know if your deficient?

According to the soil samples very low on all of them has to be some sort of limiting factor. Kernels on wheat seem to be not as plump as I would like protien was 13.5 to 14.5 so not like it should look like.by looking at copper deficiency images online would say there Is some symptoms there. Do not want to go crazy would like to do some trials though

Should say so not like it would look like if was in higher teens for protien.

Neighbors had a field they could never get bushel weight on cereals to make standards but otherwise seemed to grow good crops. They put 20lbs/ac of copper sulfate on and cured the problem, that was likely 25 yrs ago. Lots of guys figure the aborted pods on canola is as much of a boron deficiency as it is heat blast.

I put half a pound of granular copper with my wheat fert blend, more because wheat is a big user than because I've noticed symptoms. Could see the cu levels dropping on soil tests over time.

that is the reason for going to a liquid starter add cu and boron easily . boron can get added to glyphosate in first pass pre emerge

New to this so floated on 20 lbs acre of copper sulfate or blended with a fertilizer blend?

They floated on and incorporated. Copper sulfate is expensive and it's quite corrosive. The product I use is nexus copper and zinc granular and goes with fert. Not sure how price would compare by actual numbers.

For copper sulphate you could check feed mills for pricing too as they use it.

The soil tests are ppm for copper not pounds per acre. Would have to do some math or get some help to figure what you need to balance your needs. My last numbers are from .6 to .8 which is medium levels so trying to keep them there.

I've never tried it but for an immediate short term fix or where its rental land and you aren't interested in building levels there are tank mix able products you can spray on too.

Not what you were asking, but I was just doing some reading, and came across this:

In many instances, copper
fertilizer applied to copper-deficient wheat or barley
resulted in crops maturing seven to fourteen days sooner.

From Alberta Agriculture: https://www1.agric.gov.ab.ca/$department/deptdocs.nsf/all/agdex3476/$file/532-3.pdf?OpenElement https://www1.agric.gov.ab.ca/$department/deptdocs.nsf/all/agdex3476/$file/532-3.pdf?OpenElement

I don't see the typical symptoms of Cu deficiency in wheat, even though I farm some peat/organic soils, and wheat should be the most sensitive. But those areas are always very slow to mature, and sometimes have low bushel weight( which I attribute to frost, but perhaps Cu is the reason why, or a combination of the two). I was not aware of the maturity connection, so I will be trying some experiments next year to see if this is the solution.

I previously grew a variety of barley that was very succeptible to leaf disease, even in early tillering stage. And it would be much worse on organic,or high OM soils, and fungicide couldn't hardly help, so I tried applying Cu at herbicide time, and extra on those areas, and it responded very well.


This grainews article about a study that looked at all previous studies didn't find significant increase in protein when applying Cu:

“Claims that application of copper (either foliar or soil applied) increase nutrient content and in particular protein content are unfounded,” Goh and Karamanos concluded in their report.

Try impregnating on your fert blend in seed row. If u have a dealer that has a blender u can dump liquid in and will coat all the prills giving u more feeding sites for the roots
