A biomass stack covering system for applying a tarpaulin sheet on a stack of biomass bales includes a motorized vehicle having at least one steerable and driven axle and an articulated arm affixed to and movable with respect to the motorized vehicle. The articulated arm is operably configured to extend horizontally and vertically and to pivot at a proximal end thereof with respect to the motorized vehicle. A tarpaulin dispensing apparatus is operably connected to a distal end of the articulated arm and is articulable thereabout. The dispensing apparatus is configured to rotationally retain a tarpaulin roll thereon and dispense a tarpaulin sheet from the tarpaulin roll onto the Bale stack by unrolling the tarpaulin sheet from the tarpaulin roll.
