Some thoughts and notes on using herbicdes and mowing clover here in Late June....
I no-tilled soybeans into a field of cereal rye and red clover this spring with plans to kill the clover with roundup after the beans emerged. Several weeks ago I applied 1 - 1/2 quarts of glyphosate per acre which totally nuked everything except....
the clover
You can see the dead rye and other weeds but the clover is thriving despite the roundup application...
That clover was planted last fall and it is a well known fact that clover is somewhat resistant to glyphosate so at lower rates it can be an economical means of cleaning up a weedy plot.
Backpack sprayers are difficult to accurately calibrate so I suggest spraying a test area first, using care to evenly apply the gly. I have often killed young annual broadleaves and grasses with only a pint or two of roundup per acre, so consider starting light and see if you can get a kill of the undesirables with the least amount of product first.
The best way to actually kill clover is with a combinaton of glyphosate and 2-4D or tilling the clover under will do the trick.
This is a plot of Alice, KopuII and Jumbo Ladino white clovers planted at roughly 2#'s each a year ago in the spring at a cost of roughly $30 an acre via Welter Seed. High quality, high protien, drought resistant clovers at a very reasonable cost...
White clovers make an awesome insect attractant for turky and pheasant broods to safely feed in
This is heavily grazed red clover
and just as heavily grazed white clover
The white clover is blooming heavily here in Late June
So before hot dry summer weather discourages growth I clipped a test plot that has Alice white clover on one side and Imperial White clover on the other side. Deer had been feeding on both but a few weeds and grasses were coming up as shown in this pic.
I try not to "mow" the clover but rather clip it 4-6" high if possible, difficult to show in pics but these are "after mowing pics"
I made a second pass thru both clovers dropping the mower close to the ground and I'll mow that strip close each time to see if there is any long term effects.
I also had red clover seeded last fall with cereal rye
and clipped that 6-8" high to keep it flowering and fixing nitrogen so that I can till it under later this summer and achieve maximum nitrogen fixation.
When clover stops flowering and goes to seed, the plants stop fixing nitrogen...not a big deal in long term plots but for a plowdown we want them to keep "working" for us...
My berseem and oats is pretty much just berseem now as deer have lapped up the oats at a rapid rate!
I was very late getting them in due to wet weather but they'll still accomplish my goal of adding nitrogen and oragnic matter to the soil when I till them in in late summer.
In the meantime deer are foraging on the tender young berseem and becoming adapted to this new feeding area....
