Abstract: The disclosed apparatus, systems and methods relate to devices, systems and methods for on-the-go monitoring and controlled feedback in a supplemental downforce application. Certain implementations provide real-time monitoring of furrow depth via contact and non-contact approaches, some of which are combined with gauge wheel feedback to calibrate and otherwise control the application of supplemental downforce to the row unit. A combination of sensor types are employed in collecting furrow depth measurements, which can be used to adjust the supplemental downforce through a control system module. A gauge wheel load sensor may be used to modify the application of supplemental downforce.
