central - east central Minnesota - | ioway - 11/21/2012 21:54What do you think is more detrimental to a seedling and young corn plant? I know there are regional differences in decomposition and I'm not asking about decomposition. Burying the residue accelerates decomposition but puts the residue in the seed zone and root zone while sweeping the residue aside avoids those issues. However, there is the issue of toxicity of the residue if it show blow back into the row and come into contact with a young plant. What's more important a clean seed/root zone or a clean above ground zone for the young plants? The two record corn yield growing guys used a altered plow bottom to evenly mix residue in the soil profile . . .. Right or wrong, that's what they did. |
