Implementations are described herein for predicting soil organic carbon (“SOC”) content for agricultural fields detected in digital imagery. In various implementations, one or more digital images depicting portion(s) of one or more agricultural fields may be processed. The one or more digital images may have been acquired by a vision sensor carried through the field(s) by a ground-based vehicle. Based on the processing, one or more agricultural inferences indicating agricultural practices or conditions predicted to affect SOC content may be determined. Based on the agricultural inferences, one or more predicted SOC measurements for the field(s) may be determined.

A system for detecting material accumulation relative to rotating ground-penetrating tools of an agricultural implement includes an agricultural implement having a frame and at least one rotating ground-penetrating tool supported relative to the frame. The rotating ground-penetrating tool(s) is configured to penetrate into the ground to a given penetration depth. The system also includes a tool speed sensor configured to provide data indicative of a rotational speed of the ground-penetrating tool(s) and a computing system communicatively coupled to the tool speed sensor. The computing system is configured to monitor the rotational speed of the ground-penetrating tool(s) based on the data provided by the tool speed sensor, determine a threshold rotational speed based at least in part on the penetration depth of the ground-penetrating tool(s), and determine when the rotational speed of the ground-penetrating tool(s) falls below the threshold rotational speed.

A system for detecting material accumulation relative to rotating ground-engaging tools includes an agricultural implement having a frame and first and second ground-engaging tools supported relative to the frame, with the first ground-engaging tool corresponding to a different tool type than the second ground-engaging tool. The system also includes first and second speed sensor configured to provide data indicative of the rotational speeds of the first and second ground-engaging tools, respectively. In addition, the system includes a computing system communicatively coupled to the first and second speed sensors. The computing system is configured to monitor the rotational speeds of the ground-engaging tools based on the data provided by the speed sensors, determine a speed correlation between the rotational speed of the first ground-engaging tool and the rotational speed of the second ground-engaging tool, and determine when the speed correlation differs from a speed correlation threshold associated with the ground-engaging tools.

Described herein are methods and systems for generating shared collaborative maps for planting or harvesting operations. A method of generating a collaborative shared map between machines includes generating a first map for a first machine based on a first set of data and generating a second map for a second machine based on a second set of data. The method further includes generating at least one shared collaborative map for at least one of the first and second machines based on the first and second maps.

A display section displays information related to a plurality of fields. The operating section accepts a selection operation for one of the plurality of fields displayed on the display section. If the operating section accepts a selection operation for the one field, and if the position information acquired by the positioning unit corresponds to a position within the one field, the control section controls the display section to display a start button for starting the operation of the fertilizing apparatus. If an operation to the start button is accepted by the operating section, the control section starts the operation of the fertilizing apparatus, based on the work information for the one field stored in the storage section.

Control zones are dynamically identified on a thematic map and work machine actuator settings are dynamically identified for each control zone. A position of the work machine is sensed and actuators on the work machine are controlled based on the control zones that the work machine is in, and based upon the settings corresponding to the control zone. When modification criteria are met, an actuator setting in a control zone can be modified, during operation. The control zone is then divided on a near real-time display into a harvested portion of the control zone, and a new control zone that has yet to be harvested, and that has the modified actuator setting value. A record is then generated and stored, for the harvested control zone, and for the new control zone.

An agricultural zone management system and methods where a variable rate prescription (VRP) includes a plurality of equipment zones of the agricultural field that are generated based on at least one treatment dimension of a farm implement to be used in the agricultural field, and each one of the equipment zones is further defined based on one or more of an intended direction of travel of the farm implement in the agricultural field, and an intended travel path of the farm implement in the agricultural field. In addition, a treatment plan, such as a treatment rate, can be generated based on the needs of plants, soil or the like in each equipment zone.

A plough comprising: a plough body; an actuator mechanism that is configured to adjust a pitch angle of the plough body; and a controller. The controller is configured to: determine an actuator-control-signal for setting the pitch angle of the plough body based on control-data; and provide the actuator-control-signal to the actuator mechanism.

A system (1000) and method of marking soil or crops within afield with a visual strip (1001) to identify an occurrence of a detected event as an agricultural implement (10) traverses a field. The system includes an assembly (100, 200, 300, 500, 700, 800, 900) supported by the agricultural implement. The assembly includes a supply of a colored composition and an actuator (130, 330, 1030) configured to receive the actuation signals sent by the controller (80, 81). The actuator is responsive to the actuation signals to release the colored composition at the location on the field while the agricultural implement advances through the field in the forward direction of travel.

A control system for a working machine includes a ground engaging structure which performs a compaction operation by passing over a body of a harvested crop. The control system includes a controller and at least one sensor providing an input to the controller. The controller is configured to determine a state of compaction of a section of the body of the harvested crop based on at least the input from the sensor, and provides at least one output to control the movement of the working machine over the body of the harvested crop and also provides an indication to an operator of the working machine as to the state of compaction of the body of the harvested crop at a particular section thereof.
