1. A tillage implement, comprising:
a frame;
a plurality of disk gangs supported on the frame, each disk gang including a disk gang shaft and a plurality of disks spaced apart from each other along the disk gang shaft;
a plurality of load sensors configured to generate data indicative of loads being applied to the plurality of disk gangs;
a plurality of depth sensors configured to generate data indicative of depths of the plurality of disk blades of the plurality of disk gangs; and
a computing system communicatively coupled to the plurality of load sensors and the plurality of depth sensors, the computing system configured to:
determine a total load being applied to each disk gang based on the data generated by the plurality of load sensors;
determine an average load per disk being applied to each disk gang based on the determined total loads;
determine a baseline average value of the average loads per disk being applied to the plurality of disk gangs;
determine a moving baseline average value over a predetermined time period;
determine the depths of the plurality of disk blades of the plurality of disk gangs based on the data generated by the plurality of the depth sensors;
determine a threshold offset for each disk gang based on the determined depths; and
determine a plug status value for each disk gang based on the determined average loads per disk, the moving baseline average value, the average loads per disk, and the threshold offsets.
