Abstract:
A minimum tillage disk opener assembly for depositing two materials in furrows in the soil in a single pass operation as the opener moves in a forward direction over the ground, the disk opener assembly including a drawbar, a first angled disk having a leading surface and a trailing surface and defining a shadow area rearwardly of the trailing surface, the first angled disk forming a first furrow in the soil, and tube structure for depositing a first material in the first furrow; a second disk supported from the drawbar and having a forward extremity overlapping the first angled disk, the second disk having a substantial furrow opening portion lying in the shadow area of the first disk and forming a second furrow in the soil for receiving a second material and covering the first furrow as the second furrow is formed, the furrow opening portion extending laterally into one of the sides of the first furrow so the first and second furrows have substantial overlapping portions when viewed in the forward direction, and boot structure depositing the second material in the second furrow at a location offset from the deposited first material, wherein the covering of the first furrow prevents contact between the first and the second materials.
