A plow debris deflector for attachment to plows is disclosed. The plow debris deflector improves trash flow, buries stalks, stems, leaves and other debris without discing and requires low maintenance while providing excellent soil rotation and burying cover crops, trash, litter and other debris eight to ten inches beneath the surface of the soil. The plow debris deflector may include a first vertical portion having a mounting mechanism for mounting the plow debris deflector to a moldboard plow. The mounting mechanism may include a plow connecting slot so the debris deflector may be interchangeably mounted to a variety of plows. A lower portion of the plow debris deflector may be custom designed to complement the shape of the plow to which it is attached. The plow debris deflector includes a second horizontal portion, which may include a curved and twisted plate member for deflecting stalks and stems of various heights. The plate member guides the debris into the previous channel that the plow itself leaves behind while, at the same time, the remaining end of the plow is rotating the second layer of soil on top of the deflected debris, leaving from 90% to 100% of the plow debris eight to ten inches underground. The plate member may be adjustably connected to the vertical portion to permit adjustment in the forward and rearward directions.
