July 25, 2011 Agriculture Column


Well, the rain missed us again on Sunday.  They have sure been getting hammered in the middle to southern and southeastern part of the state.  Crops are looking generally pretty good; however there are some exceptions with some.  Those crops got planted a little later and into some pretty mucky ground.  Soybeans and pinto beans seem to be the most affected however I have seen some fields of wheat that have a ways to go.  Speaking of mucky fields listed below are some tips for cover crop on those acres claimed as Prevent Plant. 

·        Keep in contact with your insurance agent of what your plans are for PP acres and get assurances that your company is good with your plan.  You also need to check with FSA as their requirements could be different than your insurance company.  An example is: FSA only recognizes corn as a cover crop if it is solid seeded.

·        Keep written records of all correspondence with your agent

·        What are your objectives for a cover crop?  Are you concerned about using excess water, producing a forage for your cattle, controlling erosion or weed suppression.  Make sure you check with agent and FSA about grazing restrictions and timetable.

·        Don’t wait too long as cover crops should be planted by August 5-10 to allow time for the cover to protect the soil and use any excess moisture that is present.

·        If you are thinking of using winter wheat be sure to break that green bridge with a chemical burn down.  The green bridge is to help illuminate Wheat Streak Moassic which is caused by the Wheat Curl mite.

·        Know the source of your cover crop.  You need to make sure to adhere to the plant variety protection laws on some crops that producers are thinking of planting.  It is a violation to plant saved seed of any crops with proprietary laws, even just for cover crop. Example would be round-up ready seed.

·        Haying and/or grazing will be allowed after November 1rst. Haying or grazing before that date will result in a loss of 65% of prevent plant payments.

Herbicide timing application tour scheduled

A soybean herbicide timing application tour is scheduled for Friday, July 29, at 9 am.  The tour will take place southeast of Doyon1/4 mile south of highway 2.  Watch for the NDSU flag.  Steve Tronson graciously let us have a plot size of field soybeans to demonstrate the effects of herbicide timing and yield.  There will be four randomized demonstrations with the first treated area was with a pre-emergent.  The second randomized treatment was sprayed with weeds in the 2-5 inch range. The third demonstration weeds were sprayed at the 6-8 inch range and the last application the weeds will be sprayed at t10 inch and bigger.  The purpose of the demonstration is to sow yield differences in waiting for your herbicide application. 

We will also be demonstrating different herbicide applications using water rates of 10-15-20-25 gallons per acre.  You will see the effects of the different water usage.  We will also see if there are difference in a ultra low drift nozzle compared to the flat screen nozzle.  SEE YOU FRIDAY, JULY 29 AT 9 AM SOUTHEAST OF DOYON, SOUTH SIDE OF HIGHWAY 2.
