A soil apparatus (e.g., seed firmer) having a locking system is described herein. In one embodiment, the soil apparatus includes a lower base portion for engaging in soil of an agricultural field, an upper base portion, and a neck portion having protrusions to insert into the lower base portion of a base and then lock when a region of the upper base portion is inserted into the lower base portion and this region of the upper base portion presses the protrusions to lock the neck portion to the upper base portion.

An agricultural row cleaner having: a frame; a first row cleaner wheel disposed on a first side of the frame; a second row cleaner wheel disposed on a second side of the frame; and a third wheel attached to the frame and having a leading edge disposed forward of the first row cleaner wheel and the second row cleaner wheel along a direction of travel.

One or more techniques and/or systems for application of a supplemental downward force to a ground working implement. A mechanical advantage from a lever arm can be utilized to apply supplemental downforce to a ground working implement. A biasing force can be applied to the lever arm by a spring assembly at various locations. Moving the spring assembly along the lever arm can vary the amount of downward force applied by the lever arm to ground working implement. In some implementations, moving the spring assembly to a different end of the lever arm applies an upward force to a coupled ground working implement.

A seed trench depth sensor is adapted to mount to an agricultural implement. The trench depth sensor determining the difference between a distance measured to a bottom of the seed trench by a first sensor and a distance measured to a surface of the soil by a second sensor disposed rearward of the first sensor.

An agricultural implement system having: a row unit coupled to a tool bar of an agricultural implement; an opener system coupled to a chassis of the row unit and configured to engage soil to form a trench; a downforce system configured to apply a downforce to the row unit to adjust a contact force between the row unit and the soil; a soil condition sensor configured to detect a condition of the soil and/or an operational sensor configured to detect operation of the agricultural implement system; a closing system, configured to close the trench created by the opener system; and a controller coupled to the soil condition sensor and/or the operational sensor, wherein the controller is configured to control the downforce system and the closing system in response to feedback from the soil condition sensor and/or the operational sensor.

A processing system having: a central processing unit (“CPU”) to execute instructions for processing agricultural data; and a communication unit to transmit and receive agricultural data, the CPU is configured to execute instructions to obtain soil temperature from a soil apparatus having at least one sensor to sense soil temperature, to obtain air temperature, to determine a temperature offset based on the soil temperature and the air temperature, to obtain a predicted air temperature, and to determine predicted soil temperature for a future time period based on the temperature offset and the predicted air temperature.

In one aspect, an agricultural row unit is provided an includes a frame, an opener disc rotatably coupled to the frame and configured to open a seed trench, and an applicator assembly coupled to the frame and configured to apply a liquid. The applicator assembly including a housing and a valve coupled to the housing and configured to be in fluid communication with a fluid source. The valve is electronically powered to move to an open condition, in which fluid is configured to pass through and emit from the valve, and electronically powered to move to a closed condition, in which fluid is inhibited from passing through and emitting from the valve. The agricultural row unit also includes a closing wheel coupled to the frame and configured to close the seed trench.

A row unit for a high-speed agricultural seeder includes a leading system including an opener and a dispenser, a trailing system including a leveler and a packer, a primary force generator generating a primary force, and a packer force adjustment system generating a packer adjustment force. The primary force includes opener and trailing force portions that are transferred to the opener and trailing system, respectively. The trailing force portion includes a leveler force portion that is transferred to the leveler and a packer force portion that is transferred to the packer. The packer adjustment force is adjustable independently of the leveler force portion, such that a combined packer force equal to a sum of the packer force portion and the packer adjustment force is adjustable independent of the leveler force portion.

A processing system having: a processing unit to execute instructions for processing agricultural data; and a memory to store agricultural data, the processing unit is configured to execute instructions to obtain soil data from at least one sensor of an implement, and to determine, based on the soil data, seed germination data including at least one of time to germination, time to emergence, and seed germination risk for display on a display device.

A processing system having: a processing unit to execute instructions for processing agricultural data; and a memory to store agricultural data, the processing unit is configured to execute instructions to obtain properties for seed environment data including at least two of soil color, residue, topography, soil texture and type, organic matter, soil temperature, soil moisture, seed shape and size, seed cold germ, furrow depth, predicted temperature, predicted precipitation, predicted wind speed, and predicted cloud cover, and to determine seed environment data based on the properties.
