A thick horizontal layer of crop residue such as corn stalks, plowed under can behave much like a coarser textural layer. This why we often observe that fields with a heavy crop or cover crop that has been plowed down, can be soggy and slow to dry in the spring. Ploughs that completely flip or invert the soil can leave a single continuous layer of residue beneath the surface. This mat of residue, traps water near the soil surface and can delay field work and affect crop growth. Molboard ploughs that place the soil on edge leave residue in strips, which avoid the problem.
Residue forms a wick which helps water evaporate and traps snow.
The concern with soil textural layers all relates back to water movement into and through the soil. Both fine textured and coarser textured layers will restrict water flow. Usually finer textured layers are more of a concern when trying to remove excess water because water flow is slower and limited by the small pore size. Coarser textured layers also restrict water flow but only until the soil approaches saturation at which point the water will drain. Take a closer look, it may help you to ensure that the tile is in the right layer to get good drainage.
