Abstract
The nutrient device of the present invention includes a ground having a ground surface. The coulter is mounted for rotation about a coulter axis and the coulter penetrates the ground and makes the ground penetration below the ground surface. A cleaning wheel is mounted for rotation about a cleaning wheel axis, and the cleaning wheel extends upwardly from engaging the coulter to a cleaning wheel point spaced away from the coulter. A conduit is positioned to deliver a nutrient onto the coulter for dispensing the nutrient into the ground penetration. A closing wheel is positioned adjacent the rear of the coulter and the cleaning wheel for closing the ground penetration.
