Provided herein are methods, systems, and devices for flexible and accurate seed spacing control in a seed planting system. The various embodiments receive singulated seed from a metering device and control movement of the seed toward a seed spacing device that receives the seed. The seed spacing device, which is disposed near the soil surface, independently controls the ejection of the seed from the device and thus the spacing of the seed in the furrow.

The disclosed apparatus, systems and methods relate to devices, systems and methods for the selective application of down pressure or downforce to a row unit. Each row unit has a dual-action actuator which is in fluidic communication with the hydraulic system for independent control of the supplemental downforce. The pressure line can be directly routed to the lift chamber for a constant supply of up pressure, with down pressure selectively applied to the down chamber for accurate control of the supplemental downforce system.
