Subject: RE: No till crop rotation... Too much?


Chart86 - 11/11/2011 18:11 We are in the 1st year of actual no till and are still trying to get a rotation schedule. Can there be too much? Do l have to have a fallow period? Here is my idea. 2 years wheat. 2nd year of wheat followed by either double crop hay,Milo or a cover crop. Wheat would be harvested in June, the hay or Milo would be harvested around october. Cotton would be planted the following June, harvested in nov or dec followed by either double crop wheat or a cover crop to go back to cotton for a second year. Is this to intense? I've always heard you will wear out your soil if you over do it without a fallow period. Keep in mind, the 1st year of wheat will be a double crop behind cotton.

Your ideas are good as a starting point.  However, you cannot afford to remove residue as hay in your climate.  You need every bit of residue you can grow.  Use every means possible to preserve that residue -- use Shelbourne stripper heads on the wheat, don't run any extra openers in the soil (or anything else that tramples residue), etc.  Some of the Aussies go so far as to set up their seeder and RTK to ensure that they always plant between the previous rows -- even on wheat or barley! 

I think the only way you'd ever get by with 2 years of cotton grown consecutively would be with a cover crop between them -- a cereal such as oats.

You might want to look thru some of the threads on the no-till discussion a few pages back, along with links.
