An agricultural harvesting machine includes crop processing functionality configured to engage crop in a field, perform a crop processing operation on the crop, and move the processed crop to a harvested crop repository, and a control system configured to identify a weed seed area indicating presence of weed seeds, and generate a control signal associated with a pre-emergence weed seed treatment operation based on the identified weed seed area.

A computer-implemented method includes obtaining a weed map of a field including a crop, the weed map representing weed plant locations on the field, identifying, based at least in part on the weed map, weed seed locations that represent presence of weed seeds on the field, and generating a control signal for a pre-emergence weed mitigation operation based on the weed seed locations.

A seeding boot for a seeding apparatus mountable adjacent a soil-opening disc of a tillage implement. The seeding boot including: a boot body mountable at, or adjacent, a lower portion of the soil-opening disc; a seed distributor on the boot body, the seed distributor having at least one seed outlet spaced laterally from the soil-opening disc; a seed inlet, connectable to a source of seeds to be planted, for the seed distributor; and at least one fertiliser distributor, the at least one fertiliser distributor having at least one fertiliser outlet located rearwardly of the soil-opening disc, and downstream of the at least one seed outlet. The seed distributor has a substantially hollow distributor body connected to the seed inlet, and a pair of substantially hollow wings extend substantially laterally from the distributor body and are each provided with a respective one of the at least one seed outlets.

A laterally movable carrier is associated with a row frame. The carrier is connected to a frame member, an opener, a first outlet and a second outlet to allow for dynamically variable adjustment of the lateral separation between a first row of planted seed and a second row of planted seed, where the first row of seed is adjacent to the second row of seed.

An agricultural vehicle comprises a left frame and a right frame. A first leg extends upward from the left frame and a second leg extends upward from the right frame to connect the legs to the beam. One or more satellite navigation receivers are associated with beam to determine a position and an attitude of the beam. In on configuration, at least one row unit suspended from the beam, where each row unit has a respective planting device with an adjustable position in one or more dimensions with respect to the beam for precise application or variable application of seeds within the rows or field.

A row frame is coupled to the rear member. A first opener is configured to open the soil; the first opener is supported by or from a first support extending downward from the frame member. A first outlet is configured to dispense or apply a nutrient strip. A laterally movable carrier is associated with the row frame. The carrier supports the first opener and the first outlet. A second outlet can dispense or plant seed, wherein the first outlet and the second outlet have a lateral separation that is dynamically adjustable during the simultaneous application of seed and the nutrient strip.

A first rear member is spaced apart from the front member and positioned generally parallel to the front member. A first pair of first pivotable arms are generally parallel to each other. The first pair of first pivotable arms are rotatably connected to the front member at two front pivot points. The first pair of first pivotable arms are rotatably connected to the rear member at two rear pivot points. At least one first opener (e.g., nutrient knife or projecting, ground-engaging member) extends downward from or with respect to the first rear member.
