An agricultural implement for distributing fertilizer to a plurality of rows includes a fertilizer container, a plurality of fertilizer metering units, and a plurality of motors. The fertilizer containers are used for storing the fertilizer prior to the fertilizer being distributed to the soil. The plurality of fertilizer metering units each include a housing and a metering device positioned in the housing. The housing has an inlet configured to receive fertilizer from the fertilizer container and an outlet. The plurality of motors are each drivingly coupled to and configured to rotate at least one metering device to distribute fertilizer to a row of the plurality of rows.

Work machines, fertilizer opener assemblies for work machines, and methods of operating work machines are disclosed herein. A work machine includes a chassis, a frame, and a fertilizer opener assembly. The frame is coupled to the chassis for movement relative thereto. The fertilizer opener assembly is coupled to the frame to selectively form trenches in the soil for the deposition of fertilizer. The fertilizer opener assembly includes an actuator that is extendable and retractable to vary a length of the actuator and a cutting implement coupled to the actuator. Operation of the actuator drives movement of the cutting implement between a cutting position, in which the cutting implement makes contact with the soil to form trenches therein, and a transport position, in which the cutting implement is raised above the soil.

A ball valve assembly having a valve body with a single inline fluid passage therethrough along a central longitudinal axis. A ball valve is sealingly seated in a valve seat within the valve body. The ball valve includes at least two through-bores, each of the at least two through-bores having a central axis intersecting one another, whereby the ball valve is rotatable between a fully open position and a fully closed position. In one application, the ball valve has two bores intersecting one another such that an angle α between adjacent bore openings of the ball valve are less than 90 degrees and an angle β between other adjacent ends of the ball valve are greater than 90 degrees for applying liquid product in a seed furrow before and after each seed in the furrow but not onto the seed.

Speed control of machines and associated implements during transitions of agricultural parameters is described herein. In one embodiment, a processing system comprises processing logic to execute instructions for processing agricultural data and performing speed control of a machine and associated implement during a transition period for adjusting a setting of an agricultural parameter. A communication unit is coupled to the processing logic. The communication unit to transmit and receive data from the implement. The processing logic is configured to execute instructions to adjust the setting of the agricultural parameter and to determine a desired speed control during the transition period based on at least one of a desired transition distance and productivity during the transition period.

Described herein are implements and applicators for placement of fluid applications with respect to agricultural plants of agricultural fields. In one embodiment, a fluid applicator for applying fluids to plants in rows in a field includes a frame, a coulter connected to the frame and disposed to open a trench between the rows of plants, and at least one application member connected to the frame or to the coulter and disposed to apply fluid to a rhizosphere of the plants.

An agricultural row unit includes 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.
