1. In agricultural apparatus the combination of:
- a planter having a frame adapted to be moved up and down and seed depositing means having a discharge outlet carried by said frame,a press wheel rearwardly of said seed depositing means on a support arm pivotally connected at a front end to said frame to enable said press wheel to move up and down relative to said frame in response to surface contour changes over which the press wheel moves,a disc assembly mounted by a mounting bracket to said frame rearwardly of said seed depositing means and forwardly of said press wheel, said disc assembly including a generally vertical disc mounted about a substantially vertical axis with the disc forming an acute angle to the direction of travel and a hollow mounting shaft supporting said disc, and a feed tube rearwardly of the axis of rotation of said disc and affixed to the side of said mounting shaft to deposit material in a groove formed by said disc and with the deposited material mounted in the same relation to the seed deposited and at a substantially uniform depth, there being connected between said mounting bracket and said hollow mounting shaft, a tubular member mounted on said hollow mounting shaft, and a spacer section of a selected width connected between said tubular member and said mounting bracket, said mounting bracket being in the form of a mounting plate affixed to said spacer section and releasably attaching said spacer section and tubular member to said frame.

Abstract
Soil-treating materials are placed in the soil in a desired relation to the seed by placement apparatus that preferably follows the seed-depositing mechanism on a planter and deposits the material a selected distance to one side and below the deposited seed. The apparatus includes a disc assembly including a generally vertical disc and an upright mounting shaft together with a feed tube affixed to the mounting shaft. A mounting bracket that mounts to the planter frame slidably receives the mounting shaft and provide for vertical and angular adjustment of the disc assembly and its ready removal from or attachment to the planter.

2. In subsoil placement apparatus for soil-treating materials adapted to be moved over a ground surface of irregular contour along a crop row, the combination comprising:
-
a frame, a seed depositing means having a discharge outlet and mounted on said frame adapted to be moved up and down to set said discharge outlet of the seed depositing means at a selected depth in the soil and moved through the soil to form a furrow and deposit seed therein, a press wheel rearwardly of said seed depositing means on a support arm pivotally connected at a front end to said frame to enable said press wheel to move up and down relative to said frame in response to surface contour changes over which the press wheel moves, and a disc assembly rearwardly of said seed depositing means including a disc and a feed tube having a discharge opening, said disc assembly being mounted on said frame for forming a groove and delivering a soil-treating material into said groove via said discharge opening as said disc assembly is moved through the soil with said press wheel moving up and down in response to surface contour changes and with the deposited material maintained in the same relation to the seed deposited and at a substantially uniform depth, said mounting for said disc assembly on said frame including a tubular member adapted to be disposed upright in which a mounting shaft is slidably received, a flange section extending laterally of the tubular member to establish the lateral position of said disc in relation to seed in the soil and a mounting plate affixed to said section adapted to mount to a frame for moving said disc assembly relative to seed in the soil. - View Dependent Claims (3)

4. In subsoil placement apparatus for soil-treating materials adapted to be moved over a ground surface of irregular contour along a crop row, the combination comprising:
-
a frame; a seed depositing means having a discharge outlet and mounted on said frame adapted to be moved up and down to set said discharge outlet of the seed depositing means at a selected depth in the soil and moved through the soil to form a furrow and deposit seed therein, a press wheel rearwardly of said seed depositing means on a support arm pivotally connected at a front end to said frame to enable said press wheel to move up and down relative to said frame in response to surface contour changes over which the press wheel moves, and a disc assembly rearwardly of said seed depositing means including a disc and a feed tube having a discharge opening, said disc assembly being mounted on said frame for forming a groove and delivering a soil-treating material into said groove via said discharge opening as said disc assembly is moved through the soil with said press wheel moving up and down in response to surface contour changes and with the deposited material maintained in the same relation to the seed deposited and at a substantially uniform depth, said disc assembly including a support hub, a support shaft supported by said hub and bearing means on said shaft for supporting said disc for free rotation on said shaft, said disc assembly including a mounting shaft affixed at one end to said support hub and extending radially out from a line through the axis of rotation of said disc, said feed tube being affixed along the side of said support hub and extending at an offset position relative to said axis of rotation and generally parallel with said mounting shaft. - View Dependent Claims (5, 6, 7, 8)
