An irrigation system and method of controlling operations of the irrigation system are provided. The irrigation system comprises a plurality of mobile support towers, a plurality of structural supports, a fluid-carrying conduit, water emitters, a sensor, and a control system. The plurality of mobile support towers are configured to move across a field. The plurality of structural supports extend between the mobile support towers, and the fluid-carrying conduit is supported above the field by the plurality of structural supports. The water emitters are coupled with the fluid-carrying conduit and emit water from the conduit onto the field. The sensor is supported on one of the structural supports or mobile support towers and is configured to capture data associated with a residue cover of a portion of the field. The control system is in communication with the sensor and is configured to receive the data associated with the residue cover of the portion of the field and determine a residue cover percentage for the portion of the field based on the data.
