Been doing some research on the effects of residue cover. I came across this web page.

 What i found interesting and some of what i have been noticing is summed up in the last section.

 

Summary

By adopting continuous no-till and using residue management, more water is available for crop production. If producers don’t change their cropping practices to make use of that water, they may complain that no-till soils are too cold and wet. Or if their soils cannot store all the water is when it is available, deep percolation may occur, potentially leaching nutrients out of the root zone. Examples of changes to use the "extra" water include: increasing seeding and fertilizer rates for higher yields; implementing more intense and diverse crop rotations; using cover crops, relay cropping, or double cropping; and, for irrigators, applying less irrigation water.
