An agricultural implement includes at least one row unit having a plurality of support members, each of which is pivotably coupled to an attachment frame or another of the support members to permit vertical pivoting vertical movement of the support members, and a plurality of soil-engaging tools, each of which is coupled to at least one of the support members. A plurality of hydraulic cylinders are coupled to the support members for urging the support members downwardly toward the soil. A plurality of controllable pressure control valves are coupled to the hydraulic cylinders for controlling the pressure of hydraulic fluid supplied to the cylinders. A plurality of sensors produce electrical signals corresponding to predetermined conditions, and a controller is coupled to the sensor and the controllable pressure control valves. The controller receives the electrical signals from the sensors and produces control signals for controlling the pressure control valves.

The monitor system of claim 1, wherein the measured parameter is a force or a pressure or a position related to a distance traveled by the first soil-engaging tool. 3. The monitor system of claim 1, wherein the row monitor graphical representation includes a plurality of colors, each representing a different range of deviations between the measured parameter and the target parameter. 4. The monitor system of claim 3, wherein the plurality of colors include green, which indicates that the first measured parameter is within an acceptable range that includes the first target parameter, yellow, which indicates that the first measured parameter exceeds but does not maximally exceed the acceptable range, and orange, which indicates that the first measured parameter maximally exceeds the acceptable range. 5. The monitor system of claim 3, wherein the plurality of colors include red, which indicates a malfunction relating to the first soil-engaging tool. 6. The monitor system of claim 1, wherein the controller is coupled to one or more non-transitory computer-readable media storing thereon a plurality of machine-readable instructions executed by the controller. 7. The monitor system of claim 1, wherein the controller is further configured to: define one or more sections, each of the one or more sections including one or more row units of the plurality of row units such that no one row unit of the plurality of row units is defined to be in more than one of the one or more sections, andcause the video display to display an indication of each of the one or more sections and their corresponding row units. 8. The monitor system of claim 1, wherein the soil-engaging tool is a planter, a fertilizer coulter, a row cleaner, or a closing wheel. 9. The monitor system of claim 1, wherein at least some of the plurality of row units includes: a second soil-engaging tool,a second actuator that causes the second soil-engaging tool to be urged toward the earth according to a second actuator signal received from the controller, anda second sensor that measures a second parameter related to or indicative of the second actuator's force or pressure on the second soil-engaging tool and that provides a second sensor signal indicative of the second measured parameter to the controller, andwherein the row monitor graphical representation indicates a deviation by the second measured parameter from a second target parameter for the second soil-engaging tool for each respective one of the at least some of the plurality of row units. 10. The monitor system of claim 9, wherein at least some of the plurality of row units includes: a third soil-engaging tool,a third actuator that causes the third soil-engaging tool to be urged toward the earth according to a third actuator signal received from the controller, anda third sensor that measures a third parameter related to or indicative of the third actuator's force or pressure on the third soil-engaging tool and that provides a third sensor signal indicative of the third measured parameter to the controller, andwherein the row monitor graphical representation indicates a deviation by the third measured parameter from a third target parameter for the third soil-engaging tool for each respective one of the at least some of the plurality of row units. 11. The monitor system of claim 1, wherein the first, second, and third soil-engaging tools are selected from the group consisting of a planter, a fertilizer coulter, a row cleaner, and a closing wheel. 12. The monitor system of claim 1, further comprising a touch-sensitive interface coupled to or integral with the video display, the controller being configured to: receive, via the touch-sensitive interface in real-time as the plurality of row units are moved along the earth, a selection of a graphical representation of a first selected row unit of the plurality of row units; andresponsive to receiving the selection of the graphical representation of the first selected row unit, the controller causing the video display to display a representation of the measured parameter such that the representation of the measured parameter and the row monitor graphical representation are displayed on the same screen. 13. The monitor system of claim 12, wherein the controller is further configured to cause to be displayed on the video display a graphical portrayal of the soil-engaging tool for the first selected row unit in a color that corresponds to the same color used to indicate the deviation by the measured parameter from the target parameter for the soil-engaging tool for the first selected row unit. 14. The monitor system of claim 13, wherein the color of the graphical portrayal of the soil-engaging tool for the first selected row unit changes as the color used to indicate the deviation by the measured parameter from the target parameter for the soil-engaging tool for the first selected row unit changes. 15. The monitor system of claim 12, wherein the controller is further configured to: cause to be displayed on the video display a button indicating a row number corresponding to the first selected row unit and a graphical portrayal of the soil-engaging tool for the first selected row unit;receive, via the touch-sensitive interface in real-time as the plurality of row units are moved along the earth, a selection of the button;responsive to receiving the selection of the button, cause to be displayed on the video display a number keypad;receive, via the touch-sensitive interface, a row unit number input entered on the number keypad corresponding to a second selected row unit of the plurality of row units; andcause a graphical portrayal of the soil-engaging tool for the second selected row unit to be displayed on the video display. 16.
