The present invention discloses an agricultural implement for applying fertilizer beneath the surface of the soil. The implement has a main frame for connecting the agricultural implement to agricultural equipment. A swing arm is pivotally connected to the main frame. An adjustable actuator interconnects the swing arm to the main frame to control the movement of the swing arm with respect to the main frame. A pair of discs are mounted to the free end of the swing arm for rotation with respect to the swing arm. The discs are offset mounted with respect to one another and are angled outwardly with respect to the direction of travel of the implement. The discs form grooves for receipt of fertilizer. Fertilizer tubes are mounted to the swing arms adjacent the discs. The fertilizer tubes deposit fertilizer in the grooves formed by the discs.

Described herein are implements and applicators for placement of fluid applications with respect to agricultural plants of agricultural fields. In one embodiment, a nozzle includes a fluid inlet, a fluid outlet, and a rotatable member to rotate over the fluid outlet to selectively expose the fluid outlet to at least one opening to provide fluid flow from the fluid outlet through the opening. Upon the rotatable member rotating over the fluid outlet, a different number of openings is in fluid communication with the fluid outlet.

Systems, methods and apparatus for monitoring soil properties and applying fertilizer during a planting operation. Various sensors are disposed in ground engaging components for monitoring soil properties. The ground engaging components may have structure for opening a side trench in the sidewalls of the seed trench and may include liquid application conduits for injecting liquid into the sidewalls of the resulting side trenches.

A ground-engaging component disposed at least partially within a planting trench formed by a planter row unit in a soil surface. The ground engaging component is capable of pivoting laterally side-to-side about a pivot axis as the ground engaging component advances in a forward direction of travel. The ground engaging component may include at least one wing extending laterally outward to form a side trench in a sidewall of the planting trench as the planter row unit advances in the forward direction of travel. The at least one wing may include a fluid outlet in fluid communication with a fluid source to deposit fluid into the side trench.

An attachment assembly for the disc of a mobile agricultural device, including a washer configured to attach to a disc of the mobile agricultural device. The washer may be attached to a center location of the disc. The washer is operatively connected to a deflector bar. The deflector bar substantially prevents debris from accumulating between the disc and a fertilizer assembly attached to the disc, as the disc rotates. The deflector bar in other embodiments, may be directly connected to a fertilizer assembly, rather than to the washer.

A seed firmer and bracket combination for a planter row unit. The bracket includes a forward configured to mount to a frame member of the planter row unit. A rearward portion extends rearward of the seed tube or seed conveyor. The seed firmer includes a body having an upper portion, a tail portion, and a resilient flexible portion between the upper portion and the tail portion. The upper portion is releasably received in a vertical opening in the bracket such that the resilient flexible portion and tail portion extend downwardly and rearwardly from the bracket. The seed firmer is releasably restrained in the bracket preventing the seed firmer from moving upward, forward, rearward and downward until the upper portion of the seed firmer is disengaged from the bracket.

A mobile agricultural machine has a valve controlled to apply liquid material to a field. An application assembly defines a conduit from the valve to a distal application tip. The application assembly includes a distal conduit section that has an inner diameter that is smaller than an inner diameter of a more proximal conduit section, that is closer to the valve, than the distal tip of the application assembly.

A bracket for use with an agriculture planter including a trailing arm frame defining a pivot point thereon may include an arm bracket assembly with first and second arms. Each arm may extend from a middle portion of the bracket. First and second implements may be rotatably mounted on mounting ends of two of the arms. The middle portion of the bracket may be pivotally coupled to the trailing arm frame at the pivot point.

Described herein is an agricultural row unit that has a knife disposed ahead of the gauge wheel for delivering material to soil adjacent to a trench. In one example, an agricultural toolbar includes a frame, a wheel mounted to the frame, and a knife disposed ahead of the wheel and comprising a material delivery conduit disposed on, through, or adjacent the knife.

An implement having a frame and a soil moving implement that is attached to the frame. The soil moving implement is disposed in a row between plants for moving soil from between rows of plants to at least the rhizosphere of the plants to cover fluid that is deposited in the rhizosphere.
