Re: Corn and beans/ RR forage soybeans
The object of some of my long running threads is to provide as much complete info as possible that will always be available and hopefully answer questions on the subject for years to come.
On the subject of herbicide in RR corn and beasns...it is true that in many cases...escpecially beans that two applications of Roundup at 1 to 1/2 quarts per acre will take care of most weed problems.
In a continous corn/bean roatation or combination such as mine...with out residual or other types of herbicides one may eventually run in all types of problems.
Rotating crops certainly helps...no-till planting on sod has far less weed problems (just things to consider)
Looking back thru this thread you can see that with conventional corn, using atrazine based residual herbicide my corn was fairly free of weed problems:
However when I switched to a Roundup only program my field quickly went from this:
to this:
Of course had I watched it more closely it shouldn't have gotten that carried away but the fact is I still sprayed it 3 times and when I finally disced it down it was already 2 feet high!
This year using Dual Magnum which is a residual safe for both corn and soybeans (at a cost of approx. $22.50 and acre) my corn and beans looked like this on Friday may 19th:
My field is clean with not even a hint of foxtail at this point.
What you see in this pic is a few remmenants of the rye I disced down and a little velevtleaf which will be easily dealt with when I spray RUP...hopefully at a point when it's closer to some canopy.
Earlier in this thread I mentioned that soybean planting depth is better on the shallower side at approx 3/4" and corn approx 1 1/2" deep.
I planted all of mine at 1 1/2 and we had several pounding rains that crusted the soil.
The beans are breaking thru but as mentioned in another thread they do indeed break their necks trying to bust thru the crust.
Plant a little shallower if possible.
I'm having some light deer/turkey damage around the exterior of the field but so far it hasn't been to serious:
They have plenty of oats, peas, clover and alflafa surrounding my field...still no assurance that they won't eventually wipe it out.
If we get plenty of moisture along with my high nitrogen rate, hopefully it will out grow thier nightly "raids" /forum/images/%%GRAEMLIN_URL%%/smirk.gif
