A no-till apparatus for application of herbicide and fertilizer, soil preparation, and seeding of a cover crop in a standing crop has inter-row assemblies configured to pass along inter-row areas between adjacent row lines of standing crop plants. Each assembly includes a fertilizer applicator, a no-till soil preparation element, a cover crop seed applicator, and a post-seeding element. The apparatus may include movable auxiliary seeding units such that the apparatus may operate as a grain drill. |

1. An apparatus for simultaneous application of herbicide and fertilizer, soil preparation, and seeding of a cover crop in a standing crop in a no-till field, the plants of the standing crop defining a plurality of generally parallel row lines, a standing crop row area being defined around each row line so as to contain the row line of plants and extending between generally parallel edges to each side of the row line, an inter-row area being defined between each pair of adjacent standing crop row areas and extending between the closest edges of the adjacent standing crop row areas, the apparatus comprising:
a plurality of spaced apart inter-row assemblies each configured to pass along one of the inter-row areas between adjacent row lines of standing crop plants, each assembly including;
a fertilizer applicator operable to apply fertilizer to one of the standing crop row areas adjacent the inter-row area without substantial application of fertilizer to the inter-row area;a no-till soil preparation element operable to prepare soil in the inter-row area for cover crop seeding without forming a furrow, the soil having an upper surface with no-till crop residue disposed thereon, the no-till soil preparation element being operable to generally cut through the crop residue so as to at least break up an upper surface of soil under the residue for cover crop seeding;a cover crop seed applicator operable to apply cover crop seed across the inter-row area after the soil preparation element;a post-seeding element operable to at least partially firm the soil and provide seed to soil contact in the inter-row area after the seed applicator applies seed; andan herbicide applicator operable to apply herbicide to the inter-row area and at least part of the adjacent standing crop row areas; at least one auxiliary seeding unit, each of the at least one auxiliary seeding units being disposed in a space between two inter-row assemblies, each of the at least one auxiliary seeding units including a no-till soil preparation element, a seed applicator, and a post-seeding element, each of the at least one auxiliary seeding units being moveable between a lowered use position and a raised storage position; wherein when the at least one auxiliary seeding unit is in the raised storage position, the apparatus is operable as an inter-row apparatus that prepares the soil, applies seed and firms the soil in the inter-row areas, applies fertilizer to the standing crop row areas and applies herbicide to the inter-row and standing crop row areas; and wherein when the at least one auxiliary seeding unit is in the lowered use position, the apparatus is operable as a grain drill. |
