central - east central Minnesota -

Wicket - 11/19/2012 07:15 First year coming up doing COC is there anything I can add to my fall potash applicacation to help the stalk breakdown. Ground has been tilled already. In MN.Thanks

This time of year, soil activity is very reduced, so us northerners are at a disadvantage to residue decompensation -
If I was to consider adding anything, it would be AMS or 28,32% as it is in a form to feed microb's now, if they are moving or active. But, it's very late, and may help, if we continue with above normal temps.
Tillage is still an option. If you ripped or chiseled, hit the field with a disk and rip it agian. It'll be about the same cost as adding something from the co-op.
Thing with COC, you want the seed to get off to a great start. Black soils to have even warm soil and germination is key. The more you break up the residue into little pieces and mix evenly in the soil profile, the better chance for even, quickk soil warm up and germination in the spring.
This past spring was idea for coc conditions - I consider it one of those once in a life time type events. Quick warm up, just the right amount of moisture to work the ground and give the seed what it needed to break out.
